In the past, the brewing industry supplied the cattle feed industry with “waste” brewers grains. This was a good deal for them and the cattle industry, and helped close the resource loop. That symbiotic relationship is soon to be over, thanks to the feds:
A fight is brewing between American beer makers and the federal government over happy hour … for cows.
For centuries, brewers have given or sold the leftover grain from the brewing process to local ranchers and dairy farmers for cattle feed. But new regulations proposed by the Food and Drug Administration threaten to end that relationship.
