Stillage (Spent Grain)
Stillage is the residue left in the still after distillation, the spent grain and liquid. Part of the liquid (backset) is often reused, and the solids become animal feed or other byproducts.
Every run leaves stillage behind. The liquid backset is commonly recycled into the next mash in the sour mash process, while the wet grain is frequently sold or given to local farms as cattle feed, turning a waste stream into a sustainability and cost story worth tracking.
