Beer

Beer is an alcoholic beverage made from the fermentation of sugars, primarily derived from cereal grains such as barley, wheat, or corn. The brewing process involves the extraction of fermentable sugars from the grains, followed by the addition of hops, which provide bitterness and aroma, and yeast, which facilitates fermentation, converting sugars into alcohol and carbonation. Beer is typically categorized into two main types: ales and lagers, distinguished by the yeast used and the fermentation temperature. Ales are fermented at warmer temperatures using top-fermenting yeast, while lagers are fermented at cooler temperatures with bottom-fermenting yeast. Beer often varies widely in flavor, color, and aroma, influenced by the type of grains, hops, and additional ingredients used. It has a long history, with roots dating back to ancient civilizations, and is consumed worldwide in various social and cultural contexts.
