The FDA's New Spent Grain Rules and What They Mean for Small Breweries

Spent grain — the barley and wheat left over after mashing — has always been one of brewing’s more elegant waste solutions. Most breweries give it away to local farms as animal feed, and everyone wins: the brewery gets rid of tons of wet biomass weekly, and the farmer gets nutritious, free livestock fodder.New guidance from the FDA, finalized this spring, is complicating that arrangement for some operations. Under updated rules tied to the Food Safety Modernization Act, breweries that distribute spent grain to farms may now be required to meet certain handling and documentation standards previously reserved for commercial animal feed producers.The practical impact depends heavily on scale. Large regional breweries with established grain programs have already been navigating versions of these requirements for years. The concern is smaller operations — the 1,000 to 3,000 barrel taprooms that have been casually leaving grain for a local dairy farmer every Tuesday morning for the past decade.Industry groups including the Brewers Association are pushing back on the scope of the rules, arguing that informal farm arrangements should be exempt from commercial feed standards. Several Congressional representatives from agricultural states have signaled support for a carve-out.In the meantime, the practical advice for small breweries is to document everything: who takes the grain, how often, and in what quantities. Whether the rules change or not, that paper trail protects you.
