The dry-milling process typically yields ethanol, CO 2, and dried distillers grains and solubles (DDGS). In the wetmilling process, corn is steeped for 30-50 h at 120-130°F in dilute sulfur dioxide solution followed by germ, bran, and gluten separations. The resulting starch stream is fermented to ethanol.
