[[Grain]] consists mainly of [[starch]] granules (endosperm) inside a husk. Before the [[mashing|mash]], grain must be mechanically crushed using a mill. The crushing process breaks open the husks, exposing the starch, and also cracks the starch into smaller bits, increasing the surface area exposed to water and [[enzymes]] during mashing.<ref name=mostra>Mosher M, Trantham K.
