Distilling grain is a cereal by-product of the distillation process. The term "used grain" in a brewery usually refers to barley produced as a by-product of the brewery, whereas distillery grain is a mixture of maize, rice and other grains.

There are two common types of distillation grains:

• Wet distillery grain (WDG) contains mainly unfermented grain residues (protein, fibre, fat and up to 70% moisture content). The shelf-life of WDG is four to five days. Due to its water content, it is usually economically viable to transport WDG within 200 km of an ethanol plant.
• Dried distillery grain with solvents (DDGS) is wet distillery grain (WDG) that has been dried to 10-12% moisture content. DDGS has an indefinite shelf life and can be transported over long distances independently of the ethanol plant location. Drying is expensive because it requires additional energy. In the USA, such grain is packed and sold as a commodity.

A good way to guarantee high quality distillery grain is to use a distillery grain moisture sensor.
