Malt Miller

A malt miller is a device used to crush malted grains, such as barley, for use in the brewing process. The malted grains are fed into the miller, which typically consists of two or three rollers that rotate at different speeds. As the grains pass through the rollers, they are cracked and crushed, creating a coarse flour-like substance called grist.

The grist is then mixed with hot water in a process called mashing, which converts the starch in the grains into fermentable sugars. The resulting liquid, known as wort, is then boiled and combined with hops before being cooled and fermented into beer.

Malt millers come in various sizes and styles, from hand-cranked models for homebrewers to large automated systems for commercial breweries. The quality of the crush is an important factor in the brewing process, as it affects the efficiency of the mashing process and the flavor and clarity of the finished beer.
