Flavored liquors are liquors that have added flavoring and, in some cases, a small amount of added sugar. They are distinct from liqueurs in that liqueurs have a large sugar content and may also contain glycerine.
Flavored liquors may have a base of vodka or white rum, both of which have little taste of their own, or they may have a tequila or brandy base. Typically, a fruit extract and, in some cases, sugar syrup are added to the base spirit.
A growing segment is higher-powered flavored liquors. In that connection, maple or honey may be added. Cinnamon has become an important flavoring for many kinds of liquor, including rum, whisky, brandy, vodka and tequila. It is touted as a way to increase sales. There are many cinnamon-infused liquors on the market. See Fireball and discussion therein.
