Benefits of Buying Milled Homebrewing Grains
Whether whole or milled, grains are one of the essential ingredients in making beer. They provide starch or sugar that is used by yeasts and converted into alcohol. When purchasing your grains, you do have options, intact whole grains or milled grains.
Milled grains are required for the mashing and lautering process. Crushing the grains breaks them apart, resulting in a ground meal called grist. Milling the brewing grains (leaving their husks intact) allows for separation during the lautering process. (more info below)
