Dry Mill Ethanol Process. In dry milling, the entire grain kernel is first ground into “meal,” then slurried with water to form a “mash”. Enzymes are added to the mash to convert starch to sugar. The mash is cooked, then cooled and transferred to fermenters. Yeast is added and the conversion of sugar to alcohol begins.
