Corn distillers dried grains (DDG) and corn DDG with solubles (DDGS) are co-products of fuel and beverage ethanol distilleries. They are obtained after the removal of ethanol by distillation from the yeast fermentation of a grain or a grain mixture by either separating the resultant coarse grain fraction of the whole stillage and drying, in the case of DDG, or by condensing and drying at least 3/4 of the solids, in the case of DDGS.
