Liquors are distilled alcoholic beverages that contain a higher alcohol content than fermented drinks like beer or wine. They are made by fermenting grains, fruits, or vegetables and then distilling the mixture to concentrate the alcohol. Common types of liquors include vodka, whiskey, rum, and gin, each with unique flavors and production methods. Liquors are often used in cocktails or enjoyed straight. They can be served neat, on the rocks, or mixed with other ingredients to create various drinks. The alcohol content in liquors typically ranges from 20% to 50% by volume, making them stronger than most other alcoholic beverages.
