Chocolate mint liqueur
Chocolate mint liqueur is a type of liqueur naturally or artificially flavored with chocolate and mint. The benchmark for the style is Vandermint, which is quite difficult to track down. The importation rights are probably held by Heaven Hill, and while it does appear on some Internet wine and spirits retailers, Vandermint is obscure in today's market.
Chocolate mint liqueurs are typically creamy, fairly sweet, and low in alcohol.
