Malt beer is a beverage produced by brewing grains that have been malted, most commonly barley. Malting involves soaking the grains in water, allowing them to germinate, and then drying them. This process activates enzymes within the grain that convert stored starches into fermentable sugars.

The brewing process begins by grinding the malted grains and mixing them with hot water in a step called mashing. During mashing, enzymes break down starches into sugars, producing a sweet liquid known as wort. The wort is then boiled, often with hops, which add bitterness and aroma.

After boiling, the liquid is cooled and yeast is added to initiate fermentation. During fermentation, yeast consumes the sugars in the wort and produces alcohol and carbon dioxide. The beverage is then conditioned, filtered, and packaged.

Different styles of malt beer exist depending on the ingredients, fermentation method, and brewing techniques used. Some varieties are light and…
