홉 (Beer) is a popular alcoholic beverage made from four primary ingredients: water, malted grains, yeast, and hops. Hops are the flowers of the hop plant and are essential for adding bitterness, flavor, and aroma to the beer. They also act as a natural preservative, helping to extend the beer's shelf life. The brewing process involves fermenting the mixture of these ingredients, which transforms sugars into alcohol and carbon dioxide. There are many styles of beer, including lager, ale, and stout, each with unique flavors and characteristics. Beer is enjoyed worldwide and often served in social settings.
