LOUIS – During a recent weekday afternoon, dozens of people filled a cozy taproom at Blue Jay Brewing Company. Scattered among the tables and bar were glasses filled with the lagers that are a specialty of the St. Louis brewery.Also on tap that day was a fresh creation called New Roots. The American Lager was a hit, with many of the patrons going back to the bar for another glass.“I love it – nice earthiness,” said Bryan Schubert, who owns a brewery in Illinois. “Still nice and crushable though. That is, in reality, a good measure of beer. You want somebody to be in your taproom and be able to enjoy a few of them within reason.”It was good enough that regulars like Greg Campbell were giving it a try in addition to what they usually order.“It’s hard for me to leave my favorite German beer,’” he said. “(But) I did try some (New Roots) and said, ‘Man, that’s spot on.’ It’s full bodied, very balanced and (has a) good flavor.”Blue Jay’s owner and brewer, Jason Thompson, was also pleased with the result of the experimental beer, which he described as earthy and almost nutty, with a lingering honey-like sweetness to it.Those flavors came from his choice to use a novel grain called Kernza for 25 percent of the 600 pounds of grain needed for the whole brew, he said.“Any grain I haven’t used before, I find interesting and challenging,” he said.The Kernza kernel is much smaller than a barley or wheat kernel, he said – kind of elongated and skinny, almost flat.Those differences did pose a few challenges. Thompson said the Kernza slipped right through his mill when he tried to crush the kernels to expose the starch that’s necessary for brewing. In the end he adjusted to a different brewing technique that used a mix of milled and unmilled Kernza – and the experiment worked. That was good news for Thompson but also for Kernza advocates – who want the grain to succeed. They see in its small seeds potentially huge changes to modern agriculture.Kernza offers 'new' qualitiesMany current agricultural staples like corn, soy, wheat, barley and others are planted into the ground each growing season. After harvest the soil is left bare or farmers plant cover crops in those fields for the winter. Kernza, by contrast, stays in the ground for several years and can produce multiple harvests in that time.“It has a very deep, persistent root system that stays in the ground for multiple years – the life of the plant,” said Allison Miller, an evolutionary biologist who studies Kernza at the Donald Danforth Plant Science Center in Olivette, Missouri. “It holds soil in place, helps build new soil, absorbs water, takes up nutrients, hosts a hugely diverse microbiome and it also sequesters carbon.”That kind of plant becomes particularly appealing when searching for potential crops that can both feed people and mitigate the negative effects of farming on the planet, she said.There are thousands of perennial plant species that could be developed for agriculture. Plant researchers recently found a perennial rice that maintained better soil quality, required less labor and delivered comparable yield compared to an annual rice variety. The hope is Kernza could perform similarly. But it and other potential perennial crops face an evolutionary challenge, Miller said.Kernza comes from intermediate wheatgrass, a perennial grass native to Central Asia that was first introduced in the 1930s into the United States. It was primarily used as a forage grass; crop researchers only began breeding it as a food source for people in the 1980s.“Kernza is essentially at a 10,000-year disadvantage relative to other major crops,” Miller said. “We don’t really think we have 10,000 years to develop the future of agriculture. We really want that happening within the next century. And hopefully earlier than that.”Miller’s research seeks to bridge that gap by studying the ways perennial plants grow and allocate resources to different parts of the plant body. Understanding that could help scientists more-quickly breed a plant that could produce larger seed yields and still develop the root system that’s essential for the environmental benefits, she said. But she acknowledged her research is a long-term project.“This is not something that we could go this fall and say, ‘You know next year I’d really like to shift this soybean field to Kernza,’” she said. “That’s going to be a challenge at the scale of contemporary agriculture.”But the kind of experimentation happening at Blue Jay Brewing Company is an important step in the development of alternative grains to wheat, barley and other annual crops, she said.New markets neededKernza, which first hit the market in 2018, occupied 2,405 acres of U.S. farmland in 2023 – out of the hundreds of millions acres planted across the country. Some farmers want to access the environmental benefits from growing Kernza but the consumer market for it isn’t quite there, said Tessa Peters, director of crop stewardship at The Land Institute, which develops perennial crops including Kernza.There also aren’t many entities in the middle of the supply chain prepared to mill or process the grain, making it all the more difficult for individuals or food and beverage companies of any size to use Kernza, she said.“The market is soft and unpredictable because it’s so early,” she said. “And it’s worth saying the price has been a barrier. The yields are lower than wheat; we’re working on that.”Environmental arguments likely aren’t going to push many people to buy or consume the product, she said.“Consumers don’t really purchase based on environmental messaging,” she said. “That’s where I think Kernza really has an edge because it actually tastes great and makes delicious products.”If a large food conglomerate like General Mills or Nestle committed to using a tiny amount of Kernza in a few of their most popular products, the grain’s fortunes could quickly change, she said.“A few big companies who put 1 percent to 5 percent of Kernza in their best selling products could translate to tens or hundreds of thousands of acres,” she said. “Those big players have a lot of sway with the supply chain.”But small brewers like Blue Jay and others that are experimenting with using Kernza still have a critical role to play, she said. They are entities that have a close connection with their consumers and can help introduce the story behind Kernza.“These companies have the opportunity to be the shepherds that bring bigger companies in and say, ‘(Using Kernza) can be done effectively and at a price point that makes sense,’” she said.Nick Colombo is an owner at Switchgrass Spirits in St. Louis, which makes bourbons, whiskeys and other spirits. He agreed. Like Blue Jay Brewing, his small distillery is just beginning to experiment with Kernza.“We can do something fun and exciting,” he said. “Big-corporate whiskey is never going to do that because they have to maximize profits for their shareholders.”So while Switchgrass won’t sway the market through its purchasing power, he said, “I could see (Kernza use) growing if the name gets out there, if the demand is there, if we create a customer base.”But that’s still years away.“We’re working with these other craft-beverage manufacturers to figure out how to convert Kernza to alcohol and what it tastes like,” he said. “We’ve honestly just never had access to Kernza; it’s hard to buy.”It’s a dilemma Thompson also faced. He tapped into special connections to get the hundreds of pounds of Kernza he needed for the recent batch of New Roots. But Thompson was clear that he’d brew with the grain again.“I would like to; it depends on the availability of Kernza,” he said.Eric Schmid is with St. Louis Public Radio.
