Hop Talk with Hopmeister Al Haunold, Part VII

Buy Local, Go Green and Save Green: The Case for Mt. Hood, Liberty, Ultra and Crystal

By now you’ve noticed a theme that goes something like this.
  • Industrial brewers back in The Day (pre-1980) grew tired of paying higher prices for unreliable supplies of European noble aroma hop imports.

  • The Industrials tasked Dr. Haunold, the People’s Hopmeister, to breed noble hop surrogates with a similar oil profile but with higher alpha acid, higher yields, and superior disease resistance.

  • Dr. Haunold delivered, and then some. He delivered, but it turned out the Industrials, after driving the research and breeding, wound up seldom utilizing the new and improved noble “mimics,” as in the late 1970s they began trending away from aromatic lagers and pilseners and towards super alpha varieties for bittering only.

  • The craft breweries came along in the mid 1980s and began taking a greater interest in the noble aroma mimic “cast offs’ for uniquely American style pale ales.

  • Many crafties, however, continued to be seduced by the mystique and aura of European, Old World hops (Saazer, Tettnanger, Hallertau Mittelfrueh). They were willing to pay more, as securing ginormous supplies from afar was not a major concern for smaller, start-up brewers.

  • In recent years, the dollar has weakened against the Euro, which has resulted in higher prices for European hop imports. Meanwhile, overall annual hop acreage in Oregon has dropped significantly in the past decade.

  • Yours Truly then ends up ranting that it doesn’t make sense to pay more for low yielding and arguably inferior (well, different) hops just because of a perceived marketing boost. Form over substance! Status. Hype. Yours Truly’s head then threatens to explode when you fold in the fact that buying Euro puts Oregon farmers out of work and puts more greenhouse gasses into the atmosphere. (Quick, you’re a brewer in San Diego. What’s greener: buying hops from Hubbard, Oregon or Mainburg, Germany?)
Here we go again.

We’ve already shown that Sterling and Santiam are darn good substitutes for Czech Saazer and German Tettnanger, respectively. For many of the same reasons, the same holds true for Mt. Hood, Liberty, Ultra and Liberty, all excellent replacements for Hallertau Mittlefrueh, another august noble aroma from Old Bavaria. How old? The literature says Hallertau hops began gracing Bavarian gardens in 736 AD and sanctifying brews in about 1100.

Bigger, Better, Stronger

Dr. Haunold released all four of the U.S. mimics of Hallertauer mf between 1990 and 1993 (the “mf” refers to the “medium early’ maturation date, circa late August in Germany). For each of the above named varieties, the yields in the US are much higher. The US varieties have higher alpha acid percentages (except for Crystal). The oil profiles are comparable. The comparative risk of crop-devastating diseases, pests or climactic “acts of god” for US varieties is far lower – summer hailstorms in the German Hallertau region are not freak occurrences.

Each, with the exception of Crystal, found favor with the Industrials (viz, Anheuser Busch, Strohs, Coors, Labbats, Modelo), largely because Al boosted the alpha juice. Crystal’s alpha, however, stayed even with it’s land race progenitor at around 3-5%, and the Industrials rejected it. Al was ready to toss Crystal and would have but for the lobbying of a single hop merchant who thought the burgeoning crafties would like its aroma and he convinced Al to release it.

Al is particularly fond of Mt. Hood, which is a ½ sister of Ultra, Liberty and Crystal. It’s parentage is as follows: 2/3 Hallertauer mf, 1/6 Early Green (a UK hop that came to the US in the early 1930s and faded away with little fanfare), and 1/6 unknown German aroma male. Mt. Hood, as well as its half-sisters, are triploid cultivars, which, Al explains, means that it tends to be vigorous, higher yielding, and nearly seedless, which is a bonus for hop happy craft brewers.

The Valley is Hotter

Mt. Hood is not an early maturing hop like its Bavarian blood mother, probably on account of the differences in terroir. Summers in the Willamette Valley, with its South-North mountain ranges, tend to be much hotter and drier than the Hallertau region in Germany, which is nestled at the base of an East-West mountain chain. Mt. Hoods mature around August 27th, while the German noble mother is primed for harvest around August 25th in the Fatherland.

Take a peak at the analytics. German grown Hallertau mf is poor yielding, low alpha (3-5%), low cohumulone (20), low total oil (0.8 ml/100g), low myrcene (40), high H/C ratio (3.4), has a trace of farnesene and stores fairly to poorly. Oregon-grown Mt. Hood, by contrast, has excellent yield, higher alpha (5-7%), slightly higher cohumulone (23), twice the total oils (1.6), a lower H/C ratio (23) and stores much better.

Flavor and aroma? They are nearly super-imposable. Mount Hood: “refined, spicy aroma and clean bittering.” Hallertau mf: “mild spicy and pleasant.” Liberty: “spicy, mild, resiny, flowery.” Of course, neither Al, nor this budding hopster, would presume to be the ultimate arbiter on taste.

How about overall US consumption? Here’s where I scratch my head. It appears a few crafties continue to be willing to pay more for the mystique. In 2009, German grown Hallertau mf imported to the US ranked 17th (34,123 lbs). The US grown cultivars ranked as follows: 9th, Crystal (65,631 lbs); 20th, Mt. Hood (32,148 lbs); and 83rd out of 88, almost dead last, Ultra (250 lbs).

Missing the Boat

“They’re missing the boat,” concluded Al, when I read to him the rankings. “Mt. Hood is a superb aroma hop. I don’t understand why it doesn’t rank higher among craft brewers. Of the four Hallertau hops we bred for US production, Mt. Hood was my favorite. The flavor and aroma are excellent. High yields. Good oils. Locally grown.”

Hmmm. Why would some crafties want to spend more for German grown hops? Even if it means a bigger carbon footprint, a less reliable supply, and putting Oregon hop farmers out of work? Perhaps it’s all about the grand experience of boarding a plane to Munich in the late summer ostensibly to inspect the hop harvest. Hey, we got beerfests in the Northwest, too!

Finally, consider this. Aroma hops grow and mature differently than super alphas. They need more care, and thus their price is higher. The plots are smaller. An investment in Oregon hop farmers will help secure a diverse, reliable, sustainable, and quality pipeline in the future.

Hop History with Dr. Al Haunold, Part VI

Saazer vs Sterling: Do You Want Sizzle or Steak?

Saazer is a land race, noble aroma hop whose “Old Europe” mystique may overshadow a few telling flaws. It’s a low total oil, low alpha acid, low co-humulone classic hop renowned for its spicy and herbal flavors. Over the last 700 years, Saazer hops have survived wars, famine, invasions, Nazis and Communist collective farming in the tiny town of Zatec (formerly Saaz), in what’s today the Czech Republic, about 50 miles south of Dresden, Germany.

In 2009, Saazer (Cz) ranked as the 7th most used hop in the Brewers Association 2009 hop usage poll, just behind it’s more robust US offshoot, Sterling. Sterling, as we’ll see, may not carry the mystique of a land race Euro hop (think castles, coats-of-arms, Oompah bands), but US farmers and craft brewers love it.

The Wages of Communism

Saazer hops have been beset by unsteady availability and small yields. The acreage has not expanded in decades (centuries?) and the yields by US standards have been dramatically low, which of course has helped push up its price. It was the uncertain supply and wild price fluctuations that prompted US brewers back in the early 1980s to grow Czech Saaz in the U.S. At the time, the walls of Communism were beginning to crack and the Czech people were poised to embrace the promise of capitalism.

A prominent US brewer began growing Czech Saaz in Northern Idaho in the 1980s on a farm near the Canadian border (aka, “the Boundary Farm”), which was owned by Anheuser Busch. The latitude of the Boundary Farm was similar to the Saazer region but the former’s growing season was a tad shorter. Dr. Cal Skotland, a plant pathologist stationed at Prosser, WA found and destroyed the Prunus Necrotic Ringspot Virus in the original planting stock he got from Czechoslovakia This virus, commonly found in many older hop cultivars around the world, was probably retarding the yield of the hop back in its homeland as well as reducing its alpha acids potential, but went unheeded under a see-no-evil Communist regime.

So, in the late 1980s, the stage was set. Noble aroma? Check. Low yield in it’s Bohemian homeland? Check. Low alpha acid? Check. Low oil? Check. Throw in the Ringspot Necrotic Ringspot virus with a gathering threat of the Apple Mosaic Virus and you have all the elements of the kind of perfect hop storm that our very own Dr. Al Haunold was put on this Earth to clean up, amp up, oil up, and let her rip.

Purging the Rootstock

Al obtained virus free clones in 1990 from the Washington Experiment Station at Prosser, and immediately set to work cooking up a new cultivar. His mission: higher yield, more alpha, similar storage potential, disease resistance and a compatible oil profile.

All very good, kind sir, but wait a second. The rootstock was infected? This budding hopster was still hung up on the virus thing.

RGW: “Do you mean to tell me the noble Saazer directly from it’s idyllic birthplace was chronically infected? And that’s probably why the yields – then and now – have been so puny? Why didn’t your colleagues back East get mad as hell and knock those viral bastards out? Good lord! Didn’t the virus skunk up the beer?”

Al, being Al, of steady hand and disciplined demeanor, first calmed me down. “Viruses are not uncommon,” he assured. “Usually in about 10 to 15 years the rootstock will get infected with mechanically transmitted viruses, such as the Prunus Necrotic Ringspot virus. Roots can get contaminated when machinery moves from one hop yard to another without first being cleaned. Workers can also act as hosts if they labor in multiple yards without cleaning up first. That’s why it pays for farmers to take every precaution – steamcleaning machinery, vigorous hand washing, targeting pathogens by hand, etc -- all of which are par for the course in the Valley.”

He continued. “This is also why scientists need to constantly monitor and why growers should check their rootstock before planting. Why did my colleagues in Czechoslavakia send us virus-infected Saazer during the good glasnost times of the 1980s? I don’t know, maybe that’s all they had. The virus detection kit was certainly available in the 1970s. Detection wasn’t the problem – it was the solution. Massive acreage of infected hops would have to have been sacrificed. It takes 2 to 3 years to bring in a healthy crop, so all of that investment would’ve been lost.”

“At the same time,” Al mused, “it was a centrally planned government that didn’t readily admit to flaws or imperfections. Maybe nobody wanted to be the one to admit that the fruit of their almighty Communist labor was infected.”

Building a Bigger & Bolder Saaz Offspring

Al decided to cross the virus-free Czech Saaz female with a vigorous male plant that had Cascade and German aroma parentage with a smattering of higher alpha potential from Brewer’s Gold. His vision was to design a lush growing hop plant that would fill in the spaces between plants in each row, so it would look like a solid green wall with plenty of side-arms and lots of cones, in contrast to the sparse cone set normally obtained with Saaz plants.

“Czech Saaz have puny sidearms with short secondary and tertiary branching,” he noted grimly. “The cone volume is weak, about 20 per sidearm. We wanted longer sidearms with 30 to 50 or more cones on average. Also, Saaz cones tend to be light, brittle and smallish. We wanted something more substantial.”Done. Al bred a robust cultivar whose parentage was ½ Saazer, ¼ Cascade, 1/8th German aroma, plus a smidgen of Brewers Gold, Early Green and more mystery hop. The yields shot up about 80% (4 bales, or about 800 lbs per acre on average in Czech hop yards vs. 8 - 10 bales, or 1600 to 2000 lbs per acre, in the Valley). Alpha acid edged up from 3-4% to 6-8%, while co-humulone, one of the major alpha acids fractions stayed in the expected Saazer range. Total oil pumped up from .6 to 1.3 ml/100g, while farnesene, the characteristic Saazer hop oil component, stayed within the expected 11 – 15% range.

Meanwhile, Al’s creation retained the ostensibly ignominious title as a “poor keeper.” Al explains. “Then, as now, alpha acid retention tends to dominate the conversation particularly with super-alpha hops destined for extract production. A ‘poor keeper’ is not desirable for making hop extracts but is not a particularly bad thing with aroma hops, of course with certain limitations. For aroma hops, it’s probably desirable to be a ‘relatively poor keeper.’ Oils, as well as the acids, oxidize relatively quickly. During the beer making process, the oils break down into dozens of new compounds which,” our master of precision noted with a twinge of frustration, “by some mysterious process impart the flavor and aroma that we like.”

The Crown Sterling

“I decided to name it Sterling to keep with the currency theme. Word play with Gold had been exhausted but I wanted to suggest a solid, reliable standard, like the pound sterling. Thankfully the Brits didn’t convert their currency over to the Euro.”

Al established a four acre plot in the Valley in 1991. At around that time, Coors took an interest. The details are sketchy, but after it’s initial romance with Sterling, Coors broke it off in a few short years. Another source, not Al, who retired from the USDA in 1995, advised me that a farmer in Washington hijacked a few experimental Sterling-related rhizomes, planted them before they were ready, and harvested the cones too early before its oils fully flourished.

The net result was Coors soured on the imposter, which wasn’t a bad thing, since the crafties thereafter discovered Sterling when it was finally released in 1999 by Al’s successor, Dr. John Henning. The crafties, we know, have been hopping up their brews ever since, including Deschutes, which showcases Sterling in my favorite brew, Green Lakes Organic Ale, the brainchild of Ueber Brewer Larry Sidor.

Now you might think that an eight year lag between a promising cross and it’s public release speaks of pokiness. You’d be wrong, according to Al, a hard charging man who by no means suffers dilly-dallying gladly. It takes time to get it right. For example, he teaches, a farmer cannot rush into harvesting Sterling. It cannot be plucked before it’s time. If he does, the brewer is not likely to get the desirable oil profile or its characteristic citrusy flavor and most likely not the full alpha acids potential.

The Hop Whisperer

How does a farmer know when it’s time to pick Sterling (or other US aromas, for that matter)? Is it simply a matter of analytic testing? Or, like those warthogs who can sniff out a truffle under two feet of mud, does one instead need a sensitive snout, a delicate touch and an acute ear? For Al Haunold, it’s all about the personal touch.

“Aromas are not super alphas,” says Al, emphatically. “If you have 400 acres of Magnum, but only 4 acres of Sterling, you can’t let the economics of harvesting the alpha crop drive the harvest of the aromas. Aromas need more time. The oil has to develop.”

How does one know if the Sterling aroma hop is ready? This is the kind of question the answer to which separates the book smart from the hopyard-hardened. “You break out your magnifying glass and you pick apart a cone. Is the lupulin gland an inverted cup and pale in color? Then it’s not ready. The cup [i.e. resin gland] must runneth over— plump, full, rich and yellow. The sprig [the central axis of the cone] – if it splits easily, she’s not ready. When you rub the cone, does it squeak or rustle? It’s not ready if it doesn’t rustle.”

“Agronomics are important. It costs money to clean the picking equipment between varieties. It’s more efficient to pick everything at once, even if grown at different locations. But aromas don’t respect labor and time charts. Factory farming high alpha and artisan aroma hops just don’t mix.”

Well said, Al. And thanks for the reminder to take the time now and then to stop and listen to aroma hop wunderkinds like Sterling.

Hop History With Dr. Haunold, Part V.
Perle: Is it an Alpha Hop? An Aroma hop? Or Something In Between?

The Germans, to this day, insist Perle (pronounced Purr-lay) is an aroma hop. When grown in Germany, the alpha acid content is a reliable 7 - 8% -- not exactly the subtle levels of an esteemed Hallertauer mf, which hover below 5%. That disparity, however, as a matter of historical record never stopped German hop merchants on the hunt for premium prices from suggesting a mild Hallertau “infusion.”

Not until, that is, they were busted in the late 1970s by a scientist who, at an international meeting, stood up and said, “Wait a minute you bearded Bavarian boys in lederhosen, this hop you call Perle quacks, waddles and paddles like a Northern Brewer. Pray tell, what’s in it?” For years the Germans resisted disclosing the pedigree, vainly trying to keep the lid on the truth as long as possible, during which time they could happily exploit the alleged Hallertau lineage.

Finally, in 1978, the Germans gave up the goose and admitted their beloved Perle was actually the progeny of a Northern Brewer crossed with a male of unknown pedigree (I guess it could have Hallertau bloodlines). As hopworld “dust-ups” go, this was big – big enough to draw out the young Dr. Haunold, our very own People’s Hopmeister and delightful stickler for the truth.

Trust, but Verify

Al recalls that during the 1960s and 1970s the Germans jealously guarded their rhizomes like the proverbial rich ugly old maid with her silver spoons. But, he noted, the Germans wanted something he had just cooked up: Galena and Nugget. “So we made a trade. But I forced them to confirm that their Perle rhizomes were indeed the offspring of Northern Brewer and an undisclosed male parent. I was skeptical about their boast that Perle belonged in the vaunted noble family, so I did some testing.”

In 1980, Al propagated a plot near Corvallis, harvested same and tested it. The alpha of the German grown Perle hovered around 8%, but the alpha in the Oregon grown cones shot up to 11%, with some tests ringing the bell at 12% or slightly higher. Al and his chemists had spent years evaluating “noble aroma hops” in order to figure out their mystique so he knew a little about the major quality components that traditional brewers expected from these esteemed, boutique hops for which they had unflinchingly paid premium prices.

But what made the Oregon- grown Perle richer in alpha acids? It’s all terroir, baby. The answer, to this day, remains something of a mystery, but if Al were to speculate --speculation being a rank and vulgar practice of histrionic lawyers and pseudo-scientists, -- the good hopmeister would offer the following.

Size Does Matter

Oregon’s hop yards line up with the 45th Northern Parallel, while the German yards are further north on the 48th Latitude. As a rule of thumb, the closer a hop vine is to the equator, all other things being equal (ceterus paribus!), the higher the acid in the cone (as a % of weight). Added to which, size does matter: the smaller the cone, the bigger the alpha juice jolt (your basic inverse relationship). Oregon Perle cones were generally smaller than their German grown sisters, but probably due to a confluence of agronomic, water supply, soil quality and climactic factors, the Oregon yields tended to be higher. So there – rank, raw, crude, unwholesome speculation.

The question you have to be asking by now is, OK, how does any of this affect the price of hops in Hubbard, Oregon? Here’s the deal. Let’s say you’re a brewer. Your recipe calls for Northern Brewer. We suggest you consider Perle. Why? Oregon - grown Perle has higher yields than Northern Brewer. Indeed, the main driver of N. Brewer in the States for years was Anchor Steam Brewery, but few growers wanted to hassle with it since the yields were so low, in part because the hop was infected with several viruses.

Yields of US grown Perle (mostly virus-free) are reliably between 1,400 and 1,600 pounds. Both are touted for their “minty” or “evergreen” flavor, but Perle has higher alpha, and stores quite well – as Al puts it, “Perle is a good keeper.

Think Globally, Buy Hops Locally

If you’re vacillating between US Perle and Germany Perle, consider these factors. The US - grown Perle has much higher yields and probably more reliable (Verticillium wilt is not the scourge here that it is there).You will get 20% more alpha. You will be keeping US growers alive. Buying locally will also save you money, especially today in view of the strong Euro and weak dollar. And besides, why reward the Germans for perpetuating the myth that their Perle has Hallertau bloodlines, a ruse designed to jack up both the mystique and the price?

Finally, let’s say you want to examine those lovely cones on the vine dangling in the summer breeze. Are you going to book a flight to Munich? With Oregon - grown Perle, which matures earlier than most sister hop varieties in the Valley, you can walk the Salmon - Safe certified hop yards at the Coleman farms like a kid in the candy store. “I’ll take a bale of this, two bales of that…”

Unlike the cultivars we’ve discussed to date, Al did not breed a new Perle derivative. He was simply the first to pry a few rhizomes from the Germans and plant them in Oregon, where in fits and starts they’ve flourished ever since. In the 2009 BA Hop Usage survey, brewers surprisingly continued to buy more German Perle than US Perle (29,550 lbs vs. 21,965 lbs, respectively).

Indie Hops will plant Perle on the Coleman Farms near St. Paul, Oregon, in 2010 with our baby harvest in 2011. We’re excited to get brewer feedback as, over time, who knows exactly what exciting flavors and aromas await. Al’s expertise stops when the hops hit the boil. For that, we defer to the nose and tongue of the brewer.

Hop History with Dr. Haunold, Part IV

Santiam, US Tettnanger, Fuggles: Will the Real Tettnanger Please Stand Up?

Many of you may be buying “US Tettnanger” with the belief that you’re getting a hop that carries the same oil, aroma and flavor profile as its noble namesake from Germany.

But you’d be wrong. The so-called “US Tettnanger,” according to Dr. Al Haunold, is actually Britain-born Fuggles. Al tried to correct the misnomer back in the late 1980s, but his call for truth in advertising and science fell on deaf and dumb ears, and the myth persists today.

Lets go back to the 1980s. Anheuser-Busch (AB) was importing German-grown Tettnanger hops, a landrace noble aroma hop which thrived in a small terroir in the Southwest region of Germany near the Lake Konstanz on the Switzerland and Austrian borders. AB wanted to free itself of dependence on Germany for Tettnanger, whose oil and alpha acids profile was similar to Saazer hops from the Czech Republic.

The German Tettnanger was an early maturing hop with lower yields and thus a relatively higher price. AB began to grow a hop in Northeast Idaho which they fobbed off as “US Tettnanger.”

Dr. Haunold propagated a small plot in Oregon and noticed a few oddities. First, Tettnang was supposed to be an early maturing hop with classic bronze and reddish coloration on the main stem near the side-arm branches. AB’s version matured slightly later and the relevant regions on the main stem were dark green.

Second, Tettnang was supposed to be high in farnesene (11%), but AB’s version was much lower (4%). Our Public Hopmeister ran the usual battery of tests and discovered that ratio of alpha to beta also did not fit the expected Tettnanger profile. Hmmm. Something’s fishy. This isn’t Tettnanger, Dr. Haunold concluded – it’s actually Fuggles.

At a conference in the mid 1980s, Al raised the discrepancy with an AB apparatchik, who promptly shut him down. Al recalls the exchange: “I pointed out from the agronomics and chemistry that a mistake had been made – it would be like calling a Chardonnay grape a Pinot noir. They told me they were going to continue to use the Tettnanger appellation anyway and I shouldn’t worry about it.”

Al wasn’t going to “worry” about it. Instead, he’d gotten busy making the real deal. In the early 1980s he crossed a female Tettnanger with a male that consisted of ½ Cascade and fractions of Brewers Gold and Early Green (an early and little known English aroma variety). His goal was to closely mimic Tettnanger, which he noted had a similar profile of Saazer – “Saazer and Tettnanger are nearly the same.”

Al had just put the finishing touches on his four Hallertauer Mittelfrueh progeny: Liberty, Mt. Hood, Crystal and Ultra. “I wanted to focus on the farnesene levels and develop a Tettnanger/Saaz mimic that would produce much higher yields,” noting that in Germany typical yields in the Tettnang region were around 5 - 6 bales (about 1200 lbs) per acre, well below the desired output of about 8 - 10 bales, a threshold level above which growers could actually earn a profit. .

Dr. Haunold met his markers in 1997 with the public release of “Santiam,” an aroma hop which he named after the nearby river which flowed from the Cascades mountains into the Willamette River. Santiam’s chemistry was close to Tettnanger, explained Dr. Haunold, “with an added bonus. Santiam had a slightly higher alpha content than Tettnanger [5 to 7% vs 4 to 5%], a similar cohumulone content [21 to 24], and much higher yields. From an aroma standpoint, it’s a very good substitute for Saazer and Tettnang. The big difference is price – Santiam can be grown economically in the US and sold for far less than imports, especially today when the dollar is so weak against the Euro.”

Unfortunately, today, very few hop merchants are contracting with US growers to plant Santiam. According to the BA survey of hop usage in 2009, brewers used only 249 pounds of Santiam, compared to 77,500 pounds for Saaz (CZ) and 3,230 pounds for Tettnanger (GR). It looks like the bigger crafties (think Boston Brewing) are content paying more for European imports on the image-driven premise, oddly enough, that Euro hops carry more panache than American varieties.

Meanwhile, the great bait ‘n switch continues. According to the BA survey, in 2009 crafties used 17,921 pounds of hops that were erroneously labeled as “US Tettnang,” which we’ve known since the mid 1980s are actually Fuggles. Note to Self: At Indie Hops, we need to remember to advertise “US Tettnanger” as really “Fuggles.”

Is Dr. Haunold upset about the perpetuation of this… er… fraud? Not exactly. He chalks up the misnomer to “benign neglect” but notes that were he a German grower from the Tettnang region he’d have a bone to pick. “That appellation is worth a lot of money – Tettnang. Fuggles is a great hop, but it doesn’t carry the same weight as Tettnang. Why they don’t pursue legal action to protect the Tettnang name is beyond me.”

So there you are. Why spend more for European Saaz and Tettnang hops when you can buy Santiam, which is nearly indistinguishable, has slightly more alpha and it can be grown locally? Indie Hops will put substantial acreage of Salmon-Safe Santiam in production this year with our Oregon farmers (the original test plots for Santiam were located in the former John I. Haas “Alluvial” hop yards which are now part of the Coleman farms).

We are pleased to help revive this unsung aroma hop hero --let the Santiam run free!

Part III: Dr. Al Haunold Hop History

Alpha Obsession: Origins of the Race for More Bittering “Juice”

Today it’s well known that alpha, or “juice,” is a form of hop currency. In an industry run more and more by bean counters who are eager to sacrifice a bit of quality to make a few more pennies, when it comes to choosing hops, the juice content of a hop is more often than not the deciding factor. Put simply, the more a processor can extract from a single cone , the fewer cones he has to buy.

Where did this obsession with alpha acids begin? To answer that, I spoke to Dr. Haunold, who it turns out was on the front lines in the race for more alpha. The race began in the early 1960s with a challenge that resulted in a hunch that yielded a breakthrough that the growers hated so much they threatened to suppress it with legal action. Oh my! Read on.

Early 1960s: Pride of Ringwood Rules

In the early 1960’s, when it came to high alpha acid, a hop from Australia called “Pride of Ringwood”(PoR) ruled. It sported a hefty 11% juice content, the high-water mark for commercially available bittering hops worldwide. PoR, however, did not thrive in the US. Instead, we (especially in Oregon) relied on the UK-born Bullion and Brewer’s Gold, which weighed in around 10% alpha. One problem with the UK B&B is they didn’t store well, losing as much as 50% of their juice in 4-5 months of unrefrigerated storage.

In the mid 1960’s, hop processors began to experiment with extracting the acids from hops. They saw the future, and the future was bitter syrup served up in air tight steel canisters. A Canadian chemist, Dr. Lloyd Rigby, had years earlier discovered that alpha acid resin actually had three major components: humulone, cohumulone and adhumulone, which made up about 10 or 11 of the total weight of a dried hop cone (e.g, the B&B sisters).

Dr. Rigby seized on the juice craze. He forecasted that each percent of additional juice was worth millions, so it was well worth trying to engineer new hops with a higher alpha content. John I. Haas hired Dr. Rigby to develop a hop extraction plant in Yakima. Dr. Al Haunold met Dr. Rigby in the late 1960s, and the former challenged the “new kid on the block” to breed a new hop that pushed the alpha envelope.

“I accepted the challenge,” recalled Al, who had just joined the USDA as hop geneticist in 1965. At the time, the predominant all-purpose hop in the Pacific Northwest was Cluster, which stored well (refrigeration was uncommon in those days), carried a low price, and depending on the year and the test often rang the juice bell at close to 8 %, but was reputed to have an undesirable “black currant” aroma. The growers generally were content with Cluster.

At the time, the hop cognoscenti ordained that no hop could exceed 11-12%. They also prophesied that no high alpha could be stored more than a few months since juiced up hops were branded as “poor keepers.” Juiced up hops were also expected to have high co-humulone content (above 35 %).

Gold Fever

Undaunted, Dr. Haunold, driven by the new orthodoxy that each 1% percent alpha was a “gold mine,” began tinkering appropriately enough with hops related to Brewers Gold (BG). He started with a female BG-derived seedling that he crossed with a male (which had a sprig of BG and a sprinkle of German aroma hops in its genetic blood). “You never know for certain in science what will work, but I had a hunch that we’d strike gold with this parentage,” said Dr. Haunold.

He started in the early 1970s with 400 seedlings of the above mentioned cross and by 1976 had narrowed the lot down to 36 thriving seedlings selections. Dr. Haunold began growing the “super alpha” selections in a few replicated plots near Corvallis. Most selections showed promise for mildew resistance and above average alpha. The cones were compact, easy to pick, clean, and they dried and stored well – in a word, they were “gorgeous.”

Al knew he had the tiger by the tail when his chemist tested a few cones, read the results and suspected that somebody had “doctored the numbers,” as the alpha acid content weighed in at a scorching 13-14.5%! About 50% more juice per cone! A new world record!

Noting the parentage and the shape of the big bold cone, Al decided to name his brainchild “Nugget.” Now emboldened, our young over-achiever was ready to start growing Nugget in test plots in Idaho, California and Washington.

But a funny thing happened on the way to more juice. The Washington hop farmers grabbed their pitchforks and torches and fought back, sort of like blacksmiths shouting down the new gas-powered Iron Horses. The Washington growers were satisfied with Cluster (up to 8% alpha). A survey at the time showed that of 10 “priorities” , developing higher alpha acid hops ranked 9th, just above the bottom.

Too Good to be True

One can understand the grower’s protest. In the quest for higher juice, brewers and hop processors, who by then had figured out how to hop flowers to alpha juice, both demanded super alpha varieties. The more juice they could suck out, the fewer cones they needed, which meant that fewer acres needed to be planted. They of course did not pay extra for each percent of alpha, since they bought the cones by the pound. The Washington growers retaliated by closing their the borders to the Cluster-bustin’ Nugget, even for testing.

However, Dr. Rigby – recall, he’s the hop chemist who John I Haas hired as their Master Extractor – said “wait a minute, Nugget sounds like the Holy Grail, I want some!” So he arranged to have a few acres of the lupulinona non grata Nugget grown on J.I. Hass’ property. To be sure, our budding hopmeister certainly wasn’t a troublemaker – far from it. He was surprised by the protest. At the time, USDA hop scientists like Al under a “tristate agreement,” which included Washington, Oregon and Idaho, had a perfect right if not duty to test and evaluate hop selections in these key hop states. To prevent any one state from gaining an undue growing advantage, all 36 of the most promising selections were provided to each state under strict guidelines.

Nonetheless, the Washington Hop Commission and some of its grower members were outraged. They threatened legal action. That didn’t work. Then they threatened to order the local police to trample onto Haas’ private property and physically uproot the blacklisted Nugget rhizomes.

Dr. Rigby responded to the threats by promptly erecting a 10 foot high Cyclone fence around his precious crop and installing motion sensors and flood lights – everything short of pit bulls, claymore mines and armed Pinkerton agents. Over my dead hop! Across this line, you will not cross!

The Patience of a Public Servant

In the end, the bluff was called and Dr. Rigby nursed his Nuggets. However, because of political pressure, Dr. Haunold did not release Nugget to the public until late 1981 , even though it had been ready to roll since about 1978. Why? “I was a public servant,” said Dr. Haunold modestly. “Since a very loud fraction of public clearly did not want the fruits of my labor, I just waited until the time was right.”

But wouldn’t Nugget serve the public? I mean, this was your major opus, your brainchild, your baby? Didn’t you want to unleash your masterpiece? “No,” he replied with typical matter-of-factness. “The Hop Research Council and the Hop Commissions of several states asked me to delay release for a few years because the growers felt threatened. End of story.”

During those three years between 1978 and 1981, while Al was waiting, his
coworker in Idaho (Dr. Bob Romanko), was putting the finishing touches on his own Super Alpha pet hop. Dr. Romanko had been experimenting with a new cultivar that came to be known as “Galena.”

Suddenly, in 1980, a world-wide hop shortage struck, and the need for US grown bittering hops just ratcheted upward, as the price for alpha extract instantly quadrupled. Unlike Al, who answered to all three states, Romanko answered only Idaho’s hop commission, which basically said “bring it on!” In early 1981, the Idaho Agricultural Experiment Station at Parma released Galena to the public. Galena’s juice came in just under Nugget’s, at 12% by weight.

1980 Hop Shortage: Brewers Scramble as Alpha Spikes

The world-wide shortage of alpha acids following the 1980 harvest had brewers scrambling to obtain additional alpha, at any price. This affected especially those brewers who had not entered into forward contracts and thus had to pay as much as 11 dollars for a single pound of hops, an unheard of price at the time. Farmers did not get rich since they had long-term contracts and had to deliver at the lower contracted prices. The few farmers who had excess production (above the contracted prices) could, however, sell their non-contracted “spot hops” to the highest bidder. And bid high the brewers most certainly did.

Hop dealers now offered ever increasing prices for forward contracts of high-alpha hops, with premiums of up to 25 cents for each quarter percent alpha above 9%. Growers could make more in premiums than they could get just for a pound of hops with Galena and Nugget. Dr. Haunold responded by launching a massive Nugget propagation program and established multi-acre test plots in Oregon, Washington and Idaho, this time, without having to duck pitchforks or rotten tomatoes.

Galena rootstock was freely available at that time and Washington growers stampeded to get their hands on available root stock despite a quarantine of importing non-inspected rootstock into the state. Alpha was suddenly all the rage and its emergent value changed the way hops were priced.

Al recalls that one Oregon grower told him that he had forward contracted at the alpha premiums for 4 years starting in 1982. By early 1984, however, high alpha hops had flooded the market and the price began to slide. The dealer went back to the grower and offered to buy back their high priced contracts for 50 cents on the dollar, provided the grower would pull out his alpha plots that were contracted out for a few more years.

According to Al, the grower accommodated, even though it meant he’d be eating major labor costs. The grower had just finished stringing on the Friday before the deal was cut on a Monday; on that same day the grower ordered his foreman to go back and take the strings down as they were no longer going to be growing what they had contracted for.

What have I wrought?

Dr. Haunold looks back on those days with a mixture of pride, surprise, and perhaps even a tinge of regret. “I guess I opened the flood gates. The race for higher alpha acid hasn’t abated. We were told back in the early 1980’s after my Nugget that ‘no way’ can you breed a hop with more than 14 or perhaps 15% alpha. Now, there’s new hops juiced to the gills at over 18%, both in the US as well as in some other hop growing areas around the world. ”

“I didn’t want to make a fuss about not being able to release Nugget earlier. The farmers, it turns out, were absolutely right to be worried. The big brewers today can get the same amounts of alpha at very reasonable prices from one-third less acreage. Farmers back then and still for the most part today get paid by the bale, not alpha points. I can see why they’d resist, especially today when it seems like the alpha craze is retarding the growth and variety of aroma hops.”

Hop History with Hopmeister Dr. Al Haunold, Part II

Cascade: How Adolph Coors helped launch the most popular US Aroma Hop and the craft beer revolution

Let’s go way back to the end of Prohibition in 1933. At that time, the US government saw fit to re-energize the beer industry by re-establishing the hop research facility at Oregon State University (then Oregon State College) in Corvallis, Oregon. More beer, more jobs, less crabbiness, and more tax revenue. In 1935, Oregon ranked as the top hops producer, cultivating 26 million pounds from 30,000 acres, about 90% of which was the Cluster variety.

The USDA facility’s main objective was to save cluster hops by controlling Downy Mildew (DM), which had attacked hop-yards in the Willamette Valley with deadly force. Dr. Stan Brooks, the USDA/OSU hop breeder, had grown an open-pollinated (wind pollinated – we’ll never know the parentage) female hop having a strong Fuggle pedigree. Dr. Brooks collected and studied open-pollinated seeds from the latter hop flower, which demonstrated good resistance to DM, among other attractive qualities.

One selection from these, USDA 56013, advanced to multi-hill plots for testing and, eventually, in 1967, it was produced on a one acre plot near Salem, Oregon. USDA 56013 turned out to be a diamond in the rough, but it took a while for brewers to take a shine to its sparkle. USDA 56013 had an alpha : beta ratio similar to the imported German aroma hop Hallertauer mittelfrueh and was thought to be a potential replacement for German and Czech noble imports.

For the next three years, USDA 56013 was dutifully harvested, baled, and stored in a warehouse in Yakima. Brewers wouldn’t bite. The big boys, like Pabst, Annheuser Busch, Strohs, Reingold, Schlitz and Coors, accepted the status quo. American hops (mostly pulled from UK hops) were good enough for bittering. The US dollars was strong. It was cheaper to import moderately priced Europena aroma hops than invest in breeding and growing untested noble aroma offshoots.

Then a confluence of events in the late 1960’s gave “industrial” brewers cause for pause. A disease (Verticillium wilt) devastated the Hallertauer mittelfrueh hopyards in Germany and the price of nobles (Hallertau MF, Saaz and Tettnang) went through the roof. Coors, a large importer of German aroma hops, was faced with diminished supplies and higher prices.

The government breeders in Corvallis, to be sure, had seen this storm coming. Since the 1950s they had been evaluating new breeding lines with an eye towards winning hop independence. Dr. Haunold, who joined USDA in 1965, recalls that brewers “would rub and sniff 56013 and like it, as it reminded them of Hallertauer Mittelfreuh with slightly higher alpha. But at the end of the day they’d just throw some more money at us to continue our research and then invite us down to the bar.” No brewer up until then had even ventured to pilot-brew with 56013.

Dr. Haunold and his colleagues remained convinced that 56013, which they named “Cascade” after Oregon’s majestic mountain range, was a winner. A major brewer even chided Dr. Haunold for the name they chose for 56013, snickering that “Cascade” was the name of dishwashing powder that was popular at the time. Needless to say, for the past three decades, US mega-brewers were not seriously interested in any new hops from the USDA program, let alone Cascade.

For over 12 years, the lab-coats in Corvallis had been growing test plots of Cascade with no takers, including three years of the one-acre commercial test plot with about 2000 lbs of annual harvest (over 6000 lbs total). The bales just sat balefully in a warehouse inYakima, collecting dust and growing old.

Finally, the ice broke. In 1972, USDA scientists released Cascade to the public – the first and only new hop cultivar released by the USDA hop research program since the end of Prohibition. Adolph Coors decided to take a chance on the new and untested aroma hop and Coors would pay $1 per pound for Cascade hops. At the time, US growers were fetching about 50 to 65 cents a pound (mainly for Cluster hops). As expected, hop farmers went bonkers and began planting Cascades. In a few years, Cascade jumped to over 13% of the US hop acreage grown.

Oddly, at that time Oregonians could not even purchase Coors beer , thanks to its ignorant legislature which had deemed unpasteurized beer a menace to the public health. Al recalls with a good laugh – “they called it poison!” Note: said ban was not repealed in Oregon until the 1980s. Second note, I remember as a lad my Dad buying contraband Coors in California and secreting a case across the border. He’d share it with his college buddies and I’m not sure whether it was the flavor or the joy of sticking it to the man but boy did they carry on like kings of the world.

Coors bought millions of pounds but discovered that the Cascade hops did not mimic Hallertauer MF hops closely enough and gradually scaled back on its usage. “Cascade was unique,” said Dr. Haunold. “Moderate bitterness, more alpha bang for the buck, with a pleasant citrus-floral character. The alpha-beta ratio was similar to Hallertauer mittelfrueh , but the total oil content was higher, and cone yields were dramatically higher.”

“It’s a good thing Coors took the lead on Cascades when they did,” Dr. Haunold said. “We were at the end of our rope. We had tried everything to get brewers to experiment with Cascade. We were just going to toss out those 30 bales and send 56013 over to the germplasm library, where who knows whether anyone would’ve ever picked it up.”

“Obviously, I was very thankful that Coors liked 56013,” said Dr. Haunold, who still prefers to refer to the hops he released by their pedigree number. “Coors broke the logjam. US brewers began to assert their independence from German, Czechoslavakian and French-grown hops. It gave me a lot of work to do over the next three decades. And it helped launch the craft beer movement.”

Today, Cascade hops are as ubiquitous and American as apple pie. The recent 2009 BA Hops Survey showed that Cascade again topped the chart as the most used hop – two and half times more volume than 2nd place Centennial six times greater than third place Willamette (another Dr. Haunold creation).

So, when you’re tempted to disparage the big industrial brewers, remember this: if Adolph Coors hadn’t taken a chance and bet big on Cascades, this workhorse hop may never have found its way into your kettle and who knows how long its absence might have delayed the US craft beer revolution.

First of a series:

US Hopmeister in Chief, Dr. Al Haunold, On the Origins of Willamette.

Dr. Al Haunold served as our country’s unofficial hopmeister from 1965 to 1995 as the leading hop scientist for the USDA’s hop breeding program. During his tenure, Dr. Haunold released 15 U.S. hop varieties to the public and collaborated on at least another 8 varieties. Chances are, every time you drink a craft beer today, you’re tasting a piece of his handiwork.

Although he “retired” in 1995, Dr. Haunold has continued to advise the USDA on hop breeding and production in an unpaid capacity. His days in Corvallis, Oregon are busier than ever, shuttling between the tennis courts, the swimming pool, his office at Oregon State University, and his volunteer work for the AARP helping low income earners fill out their taxes. Time has not taken the edge off – if anything, he’s sharper than ever.

Indie Hops is pleased to consult with Dr. Haunold, who is a veritable rare book on the history of hop breeding in the US. I recently spoke with Dr. Haunold about the history of Willamette, an aroma hop which he released in the mid 1970’s and today ranks as the third highest hop used by U.S. craft brewers. Willamette has also historically been one of Oregon’s mothership hops.

Back in the 1960s, Oregon’s primary hop was UK Fuggles, named after Richard Fuggles who founded the flower in his Golding Yard in the UK. Fuggles tended to grow better in the WV than elsewhere but did not produce a very high yield. Dr. Haunold was approached by Annheuser Busch (AB), which was seeking independence from imports, about replicating a Fuggles offshoot that would thrive in Oregon, have a higher yield, earlier maturation, and slightly higher alpha content.

In the mid-1970’s, Dr. Haunold came up with 6 selections from two different crosses which he subjected to sensory testing by a panel of AB brewers (at the time, AB was the 2nd biggest industrial brewer). The eight man panel evaluated the crosses with the usual rub & sniff as well as a hop tea (called a “decoction test” back then) and pilot brews.

The panel agreed on a variety which came to be known as Columbia. However, the panel was overruled by Frank Schwaiger, AB’s Vice President in charge of brewing since the 1930s. Mr. Schwaiger pinned the blue ribbon on the selection that he thought most closely resembled an Oregon grown Fuggle (which he liked very much), which turned out to be the hop we know and love today as “Wilamette,” named after the river that flows from Eugene through Corvallis down to Portland where it empties into the mighty Columbia River.

The Coleman farms began growing Willamette in the mid 1970s. AB contracted with Goschie farms to grow a few acres of Columbia, but brewers decided against brewing with it. This was in the mid to late 1970s, before the craft revolution at a time when the market was dominated by Schlitz, Pabst Blue Ribbon, Stroh’s, Miller and AB.

Dr. Haunold’s hope was that Willamette, which not surprisingly thrived in Oregon’s lush Willamette river valley, would flourish. However, test plots in Northern California and Idaho were disappointing (low yields). The new Fuggle variant (Willamette is 11/12th Fuggle) met with resistance of a political-economic sort in Washington.

This is an interesting story. From the 1960s to early 1970’s, the overwhelmingly dominant hop variety in Washington was Clusters (about 90% of the acreage), a lower alpha bittering hop that had great storageability at a time when good refrigeration was not universal. Clusters was well suited to Washington’s terroir but had not performed well in the WV because of downy mildew.

Washington growers were so protective of their investment in Clusters they did not want to even test Willamette, except for one grower named John Segal. This was before the craft beer revolution when English varieties like Brewers Gold and Bullion dominated the Pacific Northwest hopyards. Dr. Haunold had not yet begun to breed US aroma varieties of Saaz, Hallertauer Mittelfrueh and Tettnanger (we’ll get to those in future posts).

Today, according to the 2009 BA Hops Usage Survey, Willamette ranks as the third most used hop, whereas Yakima Cluster ranks…. last, bottoming out in 2009 with 0 pounds used.

Willamette has kept Oregon growers above water for the past few decades, but production between the 2008 and 2009 crop was down about 25% and we’ve all heard about AB asking growers with whom it contracted to leave perfectly healthy Willamette cones to die on the vine in 2009. In the 1970’s, Willamette did not grow well in Idaho, so time will tell whether AB under new ownership (InBev) will shift its production to Idaho and if so whether it will do as well as in the WV.

Next installment: the history of Cascades, the Craft Beer Workhorse Aroma Hop.
