High Quality Content by WIKIPEDIA articles! A vodka infusion is a flavored liquor created when vodka is flavored by one or more other ingredients. Vodka infusions may be homemade or purchased commercially; the latter are generally called flavored vodkas. By definition, vodka infusions do not contain added sugar; such beverages are called liqueurs.The extra ingredients are added to the vodka and it is left in a sealed container for a period of time to steep. This period can range from hours to months depending on the ingredients. After this period, any solid additives are removed from the vodka and the infusion is then filtered to remove smaller particles. After this, the vodka infusion can be left to age for a period of time to allow flavors to mature.
