New resource for farms using distillers grain
Distilleries in Kentucky make 95 percent of the world’s bourbon, as well as a variety of other spirits. Distilling spirits requires the use of many different grains, including corn, wheat, rye, and barley.
After the grain is used in the distillation process, it is left over as a by-product. Distilleries often work with farmers to use the leftover grain as a livestock feed. Since the distillery industry has grown quickly over the past few years, there is much more distillers grains available than in the recent past.
Distillers grains turn rancid very quickly, sometimes lasting only a few days. This short shelf life, combined with more of the grains being available, means that it is possible a farm could have grain that it is unable to feed to livestock. If this happens, there are options on how to properly manage the leftover grain.
The Kentucky Division of Compliance Assistance (DCA) has made a factsheet that covers proper management of leftover distillers grains. The “Distilling By-Products on the Farm” factsheet [PDF] is available online.
