龙舌兰酒, or tequila, is a distilled alcoholic beverage made from the blue agave plant, primarily produced in the region surrounding the city of Tequila in Mexico. It is known for its distinct flavor, which can range from sweet to earthy, depending on the production process and aging. Tequila is categorized into different types, including blanco (unaged), reposado (aged for a few months), and añejo (aged for at least one year). It is often enjoyed neat, in cocktails like the margarita, or served with salt and lime.
