Brewing ingredient derived from grain is malt, which is a four-letter word. Malt is a key ingredient in beer and other alcoholic beverages, and is made by germinating and then drying cereal grains such as barley, wheat, rye, and oats. The germination process releases enzymes that convert the grain's starches into fermentable sugars, which are then used to produce alcohol. Malt is also used to add flavor and color to beer, and can be used to make malt vinegar, malt extract, and malt syrup.
