Step 1: Milling

A handful of grains

Grains are the first ingredient processed in every beer

The brewing process starts with grains, usually barley (although sometimes wheat, rye or other such things.) The grain is harvested and processed. This is done by heating, drying out and cracking the grain husks using large diameter smooth rollers running at different speeds. The main goal of milling the grains is to expose the starches and isolate the enzymes so that the barley is ready for mashing. It is important that the grain husk remain intact, as the husks are used to form a filter bed during lautering, the third step in the brewing process.
