Distiller's Grains

The principal co-product of the ethanol production process is Distiller’s Grains that is the product remaining after the ethanol is removed from the fermented corn mash. Distiller’s grains are the non-fermentable components of the corn.  They are rich in cereal proteins, fat, minerals, and vitamins making for a high protein, high-energy animal feed supplement marketed to the dairy, beef, swine, and poultry industries. By-pass proteins are more digestible to the animal.

Dry mill ethanol processing creates two forms of distiller's grains:

  • Distillers Wet Grains with Solubles is processed corn mash that contains approximately 70% moisture. It has a shelf life of approximately three days and can be sold only to livestock producers within the immediate vicinity of an ethanol plant.
  • Distiller's Dried Grains with Solubles has been dried to approximately 10% moisture and is a granular product that has a yellow/tan color. It has a six month shelf life and may be sold and shipped to any market regardless of its vicinity to an ethanol plant.
