Wet Distillers Grain

During the production of ethanol, yeast fermentation converts the starch component of the grain to ethanol and carbon dioxide.

As a result the remaining nutritional components, protein, fat, fibre, vitamins and minerals are concentrated three-fold and are a valuable feed for livestock.

The residue is centrifuged to separate the grain solids (wetcake) from the liquid solubles. The liquid solubles are further concentrated to produce "syrup" which can be mixed with the wetcake or sold "as is". The wetcake or Wet Distiller Grain (WDG), typically has a moisture level of 65% and may be dried further to produce Dried Distillers Grain (DDG).

Distillers grains is an excellent source of protein and still has the same energy content as dry-rolled sorghum.
