What is "vodka"?

Vodka is a clear, colorless, odorless alcoholic beverage made from fermented grains or potatoes. It is usually distilled multiple times to remove impurities and to give it a smooth flavor. Vodka typically has an alcohol content of 40-50% and is often served neat or with a mixer. It is popular in many countries around the world, and is the base for a variety of cocktails, such as the Bloody Mary, the Martini, and the Moscow Mule. Vodka can also be infused with a variety of flavors, such as citrus, herbs, spices, and fruits, to create flavored vodkas. Vodka is also used in cooking, and is often used to add flavor to sauces and marinades.
