The main ingredient in most vodkas is some kind of grain, such as wheat, corn or rye. Potatoes are another common base ingredient for vodka, according to About.com.

Vodka is distilled at least three times, then filtered, before it is sent to market. It is known for its lack of color, and companies seek to create a flavorless drink that also lacks a scent. Because of these characteristics, vodka is often mixed with other ingredients so that the flavor of the ingredient, such as soda or juice, is not affected. Some vodkas include flavorings, such as berry or citrus. These flavorings are added through steeping or the simple addition of extracts or other flavoring ingredients.
