Beer brewing is the process of producing beer by combining four main ingredients: water, malt, hops, and yeast. The process begins with mashing, where the malt is mixed with hot water to extract sugars. This mixture, called wort, is then boiled with hops for flavor and aroma before being cooled and fermented with yeast. During fermentation, the yeast consumes the sugars in the wort, producing alcohol and carbon dioxide. After fermentation, the beer is conditioned, filtered, and packaged for consumption. Different styles of beer can be created by varying the ingredients and brewing techniques, resulting in a wide range of flavors and aromas.
