Chocolate liquor does not contain alcohol. It is the smooth liquid produced by grinding the center of the cocoa bean and is just one of the transitional states of cocoa from plant to edible chocolate.
Chocolate liquor is also known as cocoa liquor, cocoa mass, cocoa paste and cacao mass. When cooled and solidified, it is sold as unsweetened, baking or bitter chocolate.
Some alcoholic beverage companies make a liqueur with a chocolate flavor, and these do contain alcohol. There are two types: creme de cacao and chocolate liqueur. Creme de cacao is made from the cacao bean with small amounts of sugar and vanilla added. Chocolate liqueur contains chocolate, cream and an alcohol base such as vodka.
