Barley

A cereal grain that is malted and used in the mash for making beer.  Malted barley (malt) is a cereal grain (barley) that has been allowed to germinate by soaking the grain in water then halting the germination process by drying.  This prepares the starches to be used at a later date by brewers who crush the malt exposing the internal endosperm, mix with heated water, and enzymes already present on the grain assist in the conversion of the grains starches to fermentable sugars.
