Grains that have been used for distilling are typically low or devoid of carbohydrates but rich in proteins; this "stillage" is a waste product to a distillery, but it still has value to farm critters. Cully and Kari House raise cows, chickens, and hogs at their family farm in Nowthen, MN. A couple times a week, Cully comes to the distilley to collect the stillage in 1000 liter tanks. Cully feeds the Du Nord stillage to livestock at his farm and occasionally drops off some eggs or meat in return. Cully's farm completes the lifecycle of Du Nord's grain: from the farm, to the distillery, back to the farm.
