The production of malt beverages (as beer or ale) from malt and hops by grinding and boiling them and fermenting the result with yeast.
Making of beer, ale, or other alcoholic beverage from malt and barley by steeping (mashing), boiling, and fermenting.
Mashing the barley releases its sugars. Yeast is then added, which contains the enzymes needed to convert the sugars into ethanol (alcohol) and carbon dioxide. Hops are added to give a bitter taste.
