Each time we brew, we extract sugar from malt to create wort (aka, sugar water). When doing so, we produce a ton of left over spent grain. Caboose decided to donate our spent grain to a local farmer as food for her animals (kind of like how humans eat barley oats for breakfast). Two to three times per week, our lovely farmer friends come by our brewery to pick up our spent grain. Why do their chickens love it so much? Since the sugar has been extracted from this grain, there is lots of protein and fiber. Which is exactly what animals need! How much spent grain? About 2,000 lbs. But we do save a little bit for ourselves to make our famous spent grain crackers.
