Alcoholic beverages are produced through the fermentation of sugars by yeasts, resulting in ethanol and carbon dioxide. Fermentation occurs in various plants and fruits to produce drinks like beer, wine, cider, and sake. Distillation separates alcohol from the fermented mixture, producing spirits like brandy, rum, gin, whiskey, tequila, and vodka. Liqueurs are flavored distilled alcoholic beverages. Beer varieties include ales, lagers, and lambic, differentiated by fermentation temperature and yeast used.
