Sheridan's is a liqueur first introduced in 1994. It is produced in Dublin by Tomas Sheridan & Sons. It is uniquely bottled, consisting of two separate sections, separated by glass, but fused together. One section is filled with a black liqueur, consisting of coffee and whiskey flavors, the other is filled with a white liqueur of milk white chocolate. When pouring into a lowball glass, the white liqueur should be gently floated on top of the black liqueur. As of 2008, Sheridan's is not available in the United States, though it can be purchased on cruise ships in the duty free shops. It is also available at several duty free shops along the Canadian border.
