Kahlua, Patron XO Cafe, Starbucks, Tia Maria, Godiva and Kamora are some of the most popular coffee liqueur brands on the market. There are many others available as well, ranging from the affordable DeKuyper coffee liqueur to Koval's more exclusive organic coffee liqueur.
What makes many of the coffee liqueurs different from each other is the base alcohol used. Kahlua is a rum-based liqueur, while Patron XO Cafe is tequila-based. Many coffee liqueurs also incorporate additional flavorings, such as chocolate, vanilla or hazelnut. Coffee liqueur is used in a variety of popular cocktails, including white Russians, B-52s, mudslides and black Russians.
