Corn Distilled Dried Grains with Solubles

Corn distillers grain is the main by-product of the distillation of alcohol from maize grain. Distilleries produce alcoholic beverages, industrial ethanol and ethanol biofuel with the following by-products (definitions are given in Processes):

Spent grains, wet grains, wet distillers grain (WDG), wet distillers grain with solubles (WDGS)
Dried distillers grain (DDG), dried distillers grain with solubles (DDGS)
Condensed distillers solubles (CDS), dried distillers solubles (DDS)
There are two main distillery processes: dry-milling distillery and wet-milling distillery. The dry-milling (or dry-grind) process is the main process for producing ethanol. This process starts with removing the bran by grinding before steeping the grain in water and results in ethanol and various “distillers” by-products. The wet-milling process starts with steeping the grains and then separates the kernel into various fractions, which allows for the production of multiple food and industrial products, including starch, fructose, oil and ethanol. This process yields numerous by-products including maize gluten meal, maize gluten feed and maize germ meal (USGC, 2012)
