Joseph Cartron uses only beans from Costa Rica and Kenya for their coffee liqueur. The mix ratio is a well kept secret and very important to get the right balance in taste. The beans are roasted and distilled in a copper bowl to get all the taste in the liqueur. Cartron mixes rum and cognac to create a perfect taste ratio with the coffee. The result is a solid coffee liqueur without colour or flavourings. You especially taste coffee, as you should.
