Beer is one of the world's oldest and most widely consumed alcoholic beverages, with a rich history and diverse styles that vary significantly across different cultures and regions. The primary ingredients in beer are water, malted barley (or other grains), hops, and yeast. The fermentation process, where yeast converts sugars into alcohol and carbon dioxide, is fundamental to its production. Styles include Lager, Ales, Lambics, Wheat Bear and Craft Beers.

The history of beer dates back thousands of years to ancient civilisations in Mesopotamia and Egypt. Over time, brewing techniques evolved, and beer has become an integral part of social and cultural traditions worldwide.
