Where does our spent grain go? Spent grain is the left over malted barley and other grains we use to produce the wort for our beers. It is a very high quality source of residual starches, sugars, fiber and protein. Heller Farms has been picking up our spent grain and feeding it to their livestock. And that's a whole lot better than seeing it end up in the landfill! Thanks Heller Farms for helping us to recycle.
