Mainstem Malt is a craft malt producer based in Walla Walla, Washington, serving Western U.S. craft brewers, distillers, and their devoted fans. The company aims to support family farms, promote the relocalization of grain economies, and advance on-farm conservation and agricultural sustainability. It emphasizes supply chain transparency, encouraging customers to trace the grain origins upstream from malted products. Among its collaborations is a 2021 partnership with Copperworks Distilling Co. to release an American Single Malt Whiskey featuring barley from a Salmon-Safe certified family farm on the Oregon side of the Walla Walla valley. This collaboration illustrates Mainstem Malt's engagement with regional producers and environmental certification programs within the craft beverage ecosystem.
