The brewing process involves the fermentation of sugars, which are extracted from the grains, by yeast. This process produces alcohol and carbonation, giving beer its distinctive taste and texture. There are many different styles of beer, each with its own unique flavor profile, ranging from light and refreshing lagers to rich and complex stouts. Beer is often enjoyed socially and is commonly served in bars, restaurants, and at various events. It pairs well with a wide variety of foods, making it a versatile choice for many occasions.
