Home brewing enthusiasts and major manufacturers alike experience the same result of the beer-making process: mounds of leftover grain. Once all the flavor has been extracted from barley and other grains, what’s left is a protein- and fiber-rich powder that is typically used in cattle feed or put in landfills.
