Barley has always played second fiddle to hops and yeast when it comes to flavoring beer. Now the grain is ready for its solo.
In two studies published this week in the “Journal of the American Society of Brewing Chemists,” a research team led by Oregon State University found notable differences in the taste of beers malted from barley varieties reputed to have flavor qualities.
Consumers aren’t going to see a barley-flavored brew anytime soon in their local pub or grocery store, but the findings are an important first step toward a potential new market for beer connoisseurs, said OSU barley breeder Pat Hayes.
We started this project with a question: Are there novel flavors in barley that carry through malting and brewing and into beer? This is a revolutionary idea in the brewing world. We found that the answer is yes, Hayes said. These positive beer flavor attributes provide new opportunities for brewers and expand horizons for consumers.
In its malted form, barley is the principal source of fermentable sugars for most beers. But barley’s flavor contributions to beer are usually ascribed to the malting process rather than the grain itself.
Barley World, Hayes’ research group at OSU, with financial support from the beer industry, began with two barley varieties thought to have positive flavor attributes in beer: Golden Promise, developed and released in Great Britain, and OSU’s own barley variety, Full Pint. They then crossbred the two. That resulted in several hundred breeding lines of genetic seed stock. Researchers grew the offspring in test plots in Corvallis, Lebanon and Madras.
But there was a logistical challenge in preparing that barley for brewing and sensory testing. OSU’s progeny of Golden Promise and Full Pint each yielded only about 200 grams of malt — not enough for a reasonable sample to produce large quantities of beer for a standard sensory panel.
That’s when OSU teamed with Minnesota-based Rahr Malting Company and New Glarus Brewing in Wisconsin. The companies had developed a brewing system that could produce a single bottle of beer from each unique malt. Dustin Herb, a graduate student in OSU’s College of Agricultural Sciences, spent almost a year at Rahr participating in the micro-malting, nano-brewing and sensory processes.
Out of that initial partnership, about 150 beers were prepared for sensory testing. Each panelist tasted the beers once and then rated them on a scale in their amount of difference compared to an industry standard control beer.
The panelists found that beer brewed with Golden Promise scored significantly higher in fruity, floral and grassy flavors. Beer with Full Pint was significantly higher in malty, toffee and toasted flavors.
The progeny are showing all possible combinations of those traits. And, since researchers had been conducting DNA fingerprinting on these progeny, they can now assign certain regions of the barley genome as being responsible for these flavors. The study also found that there were some differences based on where the barley was grown, but the genetic effect was larger than the environment.
Based on the results of more Golden Promise-Full Pint progeny, finer structure genetic mapping of barley flavor genes is underway with Rahr. Researchers are also working with Deschutes Brewery in Bend to produce more representative beers from three of the selected progeny. OSU is producing 100 pounds of malt of each variety as well as a control sample called Copeland.
All three have unique flavor attributes and are relatively easy to grow. They have outstanding malt profiles. Deschutes is prepared to brew the same beer twice for each of those three and compare that to the control. Those beers are then destined to be sent to other brewers who will conduct their own sensory panels.
In addition to Herb, OSU Barley Project members Tanya Filichkin, Scott Fisk and Laura Helgerson contributed to the research. Collaborators included scientists in England, Canada, Scotland, Spain and the U.S.
The project received funding from the following breweries: Bell’s Brewery, Deschutes Brewery, Firestone Walker Brewing Company, New Glarus Brewing Company, Russian River Brewing Company, Sierra Nevada Brewing Company and Summit Brewing Company. The Brewers Association, an organization of small and independent craft brewers, also contributed financially. Mecca Grade Estate Malt and OreGro Seeds hosted the field trials.

Brewing isn't particularly technical, right? If one can make soup, one can make beer; just acquire the needed ingredients, follow the instructions and in a matter of weeks, tada … beer! But if one takes a closer look at the process, from the viewpoint of a researcher focusing on a single ingredient, there's more than meets the eye. Pat Hayes, a barley researcher at Oregon State University (OSU), is one of the people who is diving well below the surface of currently available barley and influencing the future of barley, thanks in large part to technology that did not exist even a decade ago.
Pat heads up the OSU barley project, which focuses, in part, on exploring the creation of a strain that’s specifically designed to appeal to craft brewers. The theory is that by selectively breeding specific barley strains, researchers can produce one that will not only influence the flavor of beer, but also gain unique characteristics due to the terroir, or the environment in which it’s been grown. Terroir is a term more commonly used by winemakers and understandably so, since most barley grown to be malted comes from multiple states. Oregon "is an epicenter of craft brewing and distilling," according to Hayes, but even as these industries have grown, less and less Oregon-grown barley is being utilized. Pat hopes to change that by creating a variety that will not only grow well in Oregon, but will also perhaps contribute unique flavors to beer BECAUSE it’s grown here.
Considerable work in breeding and selecting has already been done by Pat and his team at OSU to the point where an experimental variety called Oregon Promise is being grown on test plots. The name was developed because the strain came from a cross of Full Pint, which is bred in Oregon, and Golden Promise, which grows in Scotland and is a favorite of craft brewers. These test plots provide far less than the minimum 30,000 pounds of grain for the smallest batch at Great Western Malting based in Vancouver, Wash. or even the relatively diminutive 1,000 pound batches malted at Mecca Grade Estate Malt in Madras. To solve that problem in the first phase of breeding, Pat and other barley breeders around the world use "micro malters," machines that can malt just a few hundred grams of barley. The machines aren’t cheap — they can run as high as $100,000. But these malters can steep, germinate and kiln around 50 samples of this size at one time, an essential first step in breeding to produce flavor in beer. New Glarus Brewing in Wisconsin, one of the partners in OSU’s program, have pioneered a technique to brew a single bottle of beer from less than 200 grams (a little more than 7 ounces) of malt and are using it to test samples of Oregon Promise. The next step up is a mini-malting machine, one of which OSU recently purchased, that’s housed in a room about the size of a two-car garage. It will be able to produce 200 pounds of malt per run and should be ready to begin operating in October.
Once the barley has been malted, it's ready to be used to brew beer. But outside of the technique New Glarus Brewery has developed, researchers still need to make very small batches. A consumer product that recently hit the market, PicoBrew Zymatic, is a potential gold mine to barley researchers. Not only does the product make just 2.5 gallons of beer per batch, it allows for people across the country to brew on the exact same equipment.
At this point one might be wondering why brewing with the exact same equipment in multiple locations should matter to researchers exploring an Oregon-grown variety of barley. The answer is that in order to determine if this particular variety of barley does indeed contribute unique flavor profiles to beer, it needs to be grown in different places.
If this process seems like an awful lot of work, it is, but it’s one that without those technological advances would make small-batch malting and brewing prohibitively expensive for most. In the long run, the potential economic impact of this work for Oregon-grown barley could be substantial. Just think — in the future, craft brewers may be clamoring for Oregon Promise malt, made from barley that is only grown in Oregon because of the unique flavor profile it adds to their beer.
Barley may be the most overlooked ingredient in beer, but it plays a critical background role that Oregon State University professor Pat Hayes likens to the bass solo in a song. Additionally, researchers are working on creating new varieties of barley and farm trials are underway. Pictured here is a combine harvesting Rogue’s barley fields last summer.

Of the four ingredients in beer, barley is perhaps the most underrated. It doesn't have the flashiness of hops, with new varieties seemingly coming out every day. It doesn't have the environmental gravitas of water, the most abundant ingredient in beer by volume. It doesn't have the lingering mystique of yeast that harkens back to the time before yeast was a recognized beer ingredient. That leaves barley, the most predominantly used grain for malt, as the often-overlooked ingredient. But just like "no one puts Baby in the corner," barley is deserving of its own time in the spotlight.
While barley tends to get taken for granted, Oregon State University barley breeding and products professor Pat Hayes puts it in perspective saying that, "Without malt there wouldn't be the opportunity to showcase hops and yeast. It plays a critical background role but rarely gets to move to the front." He likens being able to pick the flavor of barley out in a beer to picking out the bass solo out in a song. The comparison is apt because base malts, which are lightly kilned and have low color, don’t provide much flavor. That isn't to say there is no contribution to beer's flavor from malt; in fact, there are a wide variety of specialty malts that do contribute more distinct characteristics. Craft brewers by far use more specialty malts than mainstream, adjunct brewers and have been the primary drivers in the growth and evolution of the specialty malt market.
Before malt is created, barley must be grown, most of which is called spring barley that is planted in the spring and harvested in the fall. As an agricultural crop, barley provides some potential challenges for farmers. The revenue per acre for can be lower than what could be made growing other crops, setting up a situation in which it may be replaced with more lucrative crops. In addition, there is a secondary market for barley that doesn’t meet the specifications of malting companies. But that market — animal feed — is priced in favor of other crops, corn in particular, whose price is lamentably low due to national policies. Sadly, it may be cheaper for an Oregon farmer to buy Midwest-grown corn for feed than it is to purchase a neighboring farmer's barley.
Finally, barley grown for malting requires it to be a still-living thing, 99 percent viable, when it arrives to be processed into malt. That viability is influenced by handling during harvest and transport (an extra logistical consideration) as well as the moisture content at the time of harvest. Fall rains can be detrimental to the quality of the barley, a risk that’s minimized when malting companies contract with farmers in diverse geographical areas and supplement their spring barley crop with winter barley, which is typically harvested about a month earlier. Great Western Malting, a historical West Coast supplier to craft brewers, buys barley from northern California up through Washington and east to Idaho and Montana.
The variety of barley each farmer grows is based on the suitability of the climate it's grown in and provides only minor differences that are negated by malting. The process of turning barley into malt can be compared to turning bread into toast, one in which it is the process that is more influential on the finished product than what the starting product was. Great Western Malting produces 30 different types of malts to provide craft brewers with the variety and selection that they seek.
With that said, the starting product — the barley itself — is an area that continues to evolve as well. Researchers like Pat Hayes at Oregon State University are exploring the creation of new varieties of barley, which beyond having the ability of being malted into different types, may actually contribute their own unique flavors to beer. One such exploration is the crossing of Golden Promise, a barley strain that produces a malt craft brewers favor, with Full Pint, a variety that some hope will yield unique flavors. The hybrid creation, called Oregon Promise, is currently being grown in Madras. Oregon State University is in the process of conducting farm trials, moving beyond small plot production and working with industry partners who are starting to make the tiniest batches of beers with the grain.
Digressing slightly, standard batches of barley to be malted range from 30,000-350,000 pounds where as 5-by-20 test plots can be expected to yield only around 11 pounds. There’s no simple way to malt that small of an amount, currently. But that’s not stopping some from figuring out a way to do so, providing researchers with a way to determine whether they’ve gotten the results they were hoping for in the preliminary stages. One such venture is related to Pat Hayes' work in which Wisconsin's New Glarus Brewing Company has been able to develop a process utilizing less than a half a pound of malt to make a batch of beer that is equivalent to a single bottle. There’s a big gap between that highly specialized process and the smallest batch size of 30,000 pounds from Great Western Malting.
Just as craft brewers respond to the demand of consumers, so too is there at least one malting company working to fill the gap in malt batch sizes. A student from Pat Hayes' program is heading to Rahr Malting Company in Minnesota to work on a small scale malting/brewing/analyzing pipeline. The outcome of that work should expedite the exploration of barley’s contribution to beer flavor, starting with the Oregon Promise variety.
Developments like creating new barley strains, malting previously unheard of small batches and making a single-bottle batch of beer are exciting. And it’s things like this that may result in barley becoming the next frontier in craft beer.

With the explosion of craft beer, so too has come an explosion in beer writers who are celebrating the industry through the publishing of books, articles and blogs. One of those beer writers is Fred Eckhardt, who started tackling the subject when the founders of the craft beer industry were still homebrewing. His "A Treatise on Lager Beers" was published in the early 1970s, followed by books on beer styles and sake. His extensive career also includes writing for The Seattle Times and The Oregonian as well as magazines like All About Beer.
Before he began his writing career, he was in the Marines and one of the impacts the Bay of Pigs invasion had on him was to make him ponder life after a nuclear holocaust. According to an interview with John Foyston, Fred said, "I realized that if you could brew alcohol you would be welcome in whatever shreds of civilization might remain after a nuclear war, so I took a good homebrew recipe and made my first batch of beer." Whether he was being entirely serious or not, his early forays in homebrewing were the beginnings of a career that would impact the craft beer world for decades.
Since those early days, beer writing has gathered steam with technical books like Fred's to ones telling the stories of the folks living their brewing dreams. The stories behind how each person came to be a beer writer are as varied the number of beer styles. Brian Yaeger, who wrote "Red, White, and Brew: An American Beer Odyssey," didn't know he was going to write a book until he announced it to a classroom during the pursuit of his master’s in professional writing. Once it was out of his mouth, he couldn't take it back. And before he knew it he'd secured a media pass to the Great American Beer Festival. From there he embarked on a six week road trip across the country. He describes the book as being "about the people, less so the beer."
Brian knew he'd write a second book but it wasn't until his publisher proposed "Oregon Breweries" that he knew what it would be. As luck would have it, he had already created the outline for it during the road trip that brought him and his wife from California to their new home in Portland. After retrieving the handwritten journal, he began two years of work during which the number of breweries in Oregon was growing exponentially. In the end, he had gathered the details on 190 breweries and brewpubs and was even more qualified to show visitors around, one of the things he loves most about being a beer writer.
Pete Dunlop, author of the 2013 book "Portland Beer: Crafting the Road to Beervana" started writing for the daily paper at Washington State University during graduate school. He went on to teach high school journalism and then had a career in marketing communications before going freelance. As opposed to Brian's books that are more contemporary, Pete's book is primarily historical in nature, no doubt influenced by his master’s in history.
When asked about his favorite part of being a beer writer, he replied that, "Beer people are easy to talk to," noting as well that he enjoys being able to write about the good in the industry (and sometimes bashing AB InBev). On the flip side, he noted that making money as a beer writer can be challenging. For him, publishing articles and authoring a beer blog were steps that led up to the realization that getting a book published was an important next move to make progress in this career. He's found magazine work easier to come by after publishing his book and is looking forward to writing a second historically based book.
Newer to the craft beer world is Steven Shomler, author of the just-released "Portland Beer Stories." Before 2007 he was not a beer drinker, having tasted the "crap beer" his dad drank and hating it. It wasn't until he was filming a hop harvest that he experienced what he described as "a life-changing experience." Smelling the hops in the field, during processing and in the drying room, opened his eyes and "stupid palate" to a world he didn't know existed. Later that day, he tried his first triple IPA and a whole new world opened to him, a world that he was able to write with a newcomer's perspective. However, he was new only to craft beer, as this would be his second book, following one about Portland's food cart scene. The realization that he was not going to be able to do a comprehensive piece was his biggest challenge so instead he focused on a mix of the old (McMenamins and Widmer) and the new (PINTS and Culmination). Finding stories to write about was easy as the brewers made themselves accessible, a sharp contrast to his experience with the wine industry.
The forthcoming "The Beer Bible" by Jeff Alworth is a product of his travels during two years visiting an array of amazing breweries overseas. It wasn't something that he had planned on writing; instead it was at the request of Workman Publishing, who had turned down his pitch for another book. They were looking for a follow up to "The Wine Bible" and sent him a copy, requesting he submit a table of contents as his "pitch." It was perhaps an unconventional way of finding the right author, but Jeff "didn't have anything to lose." After all, they were approaching him instead of the other way around and so he didn't stress about it.
Workman was happy with the table of contents Jeff submitted and after more than a year in contract negotiations, Jeff began the task of researching and writing his book that is broadly divided by beer styles. Since beginning work on the book in 2011 he has accumulated countless hours of stories about brewers all over the world, facilitated largely by making contacts with importers. Some countries he could have navigated on his own, the ones where English is commonly spoken, but it was destinations like Italy where he would have struggled without help arranging visits and translating.
Unlike Steven, Jeff had been a huge beer fan for years, having downed plenty of Henry Weinhard’s back when it was big, attending graduate school in Wisconsin when New Glarus Brewing opened and producing his own beers. That background, and having written ever since he was a kid, was the perfect combination that helped him begin his writing career, which started when he took over the beer column at Willamette Week following William Abernathy's departure. He went from there to write countless pieces for other publications.
Whether you prefer shorter pieces or books, historical or contemporary topics, there's something for everyone when it comes to beer writing. The best part is that they celebrate the day in and day out work that brewers do to fill our glasses. Cheers to the pioneering writers who first took it up and those who have followed in their steps!
