Beers are alcoholic beverages made from four primary ingredients: water, malted grains (usually barley), hops, and yeast. The brewing process involves fermenting the sugars from the malted grains, which produces alcohol and carbonation. There are many styles of beer, including lager, ale, and stout, each with unique flavors and characteristics. The alcohol content in beers typically ranges from 3% to 12% by volume, although some craft beers can be stronger. Beer is often enjoyed socially and is commonly served in various settings, from bars to home gatherings. It is also a popular choice for pairing with food, enhancing the overall dining experience.
