As someone who is pretty much lager-focused in my brewing, I don’t usually spend much time thinking about American Lagers. That changed after a trip to San Diego. I tried the Kernza Lager from Pure Project and walked away wanting to brew my own take on a sustainable lager built around organic ingredients. Kernza is tough and pricey to source as a homebrewer, and Montana Craft Malt doesn’t offer an organic option, so I turned to Admiral Maltings in California since they grow and sell some organic varieties. The yeast was trickier. White Labs strains in the States aren’t certified organic, only the ones coming out of Copenhagen, so I had to work around that. I also used clarity ferm to help drop the gluten levels in the finished beer. I don’t usually rely on clarity finings. When I lager my beers I stick to a slow cold crash, cold temps, and time.
This approach ended up paying off because this recipe went on to score a 45 out of 50 in the 2025 Badger Brew off competition, which was a pretty awesome surprise for something that started as a simple experiment in sustainability.

From Field to Fermentor: Believing in American Malt
For a long time, homebrewers have been told that imported malt is the gold standard. If it’s not from Germany or the U.K., it’s not the “real thing.” You hear people say they only use Weyermann for lagers or Crisp for English ales. Those are great malts, no doubt, but it’s time we start giving…
Brewing a New Zealand Style Cold IPA with Billy’s Tavern
Cold Koura is my version of a Cold IPA. It’s clean, crisp, and super hop-forward without being heavy. I layered a bunch of hops to make it interesting.
