Distillers dried grains

From Wikipedia, the free encyclopedia

Distillers dried grains is a cereal byproduct of the distillation process. There are two main sources of these grains. The traditional sources were from brewers. More recently, ethanol plants are a growing source. It is created in distilleries by drying mash, and is subsequently sold for a variety of purposes, usually as fodder for livestock (especially ruminants).

In beer or whiskey production, or in an ethanol plant, grains such as corn are ground to a coarse consistency and added to hot water. After cooling, yeast is added and the mixture ferments for several days to a week. The solids remaining after fermentation are the distillers grains.
