In one aspect there is provided a method for producing ethanol and distiller's dried grains and solubles (DDGS). This method comprises the steps of: providing a plurality of feedstocks； milling said feedstocks； mixing the milled feedstocks into a feedstock blend； producing ethanol from the feedstock blend using a dry milling process； and collecting the DDGS by-product, after the ethanol is produced. In another aspect, the method further comprises providing barley as one of the feedstocks and peas as a second feedstock, wherein the barley feedstock and pea feedstock is mixed in a ratio of between 2:1 and 3.5:1 to make the feedstock blend. In yet another embodiment, antifoaming enzymes are added during the dry milling process to reduce foaming during the fermentation stage of the dry mill process.
