Unflavored vodka has a very small amount of sugar, generally less than 1 gram per ounce of vodka. Unflavored vodka does not contain sugar aside from what is left behind after the distilling process. Vodka is distilled from fruits, vegetables and grains, some of which have natural sugars.
While most unflavored, distilled vodka contains less than a gram of sugar, some flavored vodka varieties do have sugar. Compounded flavored vodka is made with sugary flavorings, causing it to be flavored as fruit, whipped cream or various desserts. This vodka is usually 70-proof, which is 25 percent alcohol. Infused flavored vodka has little to no sugar.
