Rumpleminze
From Wikipedia:
RumpleMinze is a German-style liqueur brand, best known for their peppermint schnapps. The brand is owned by the alcoholic beverage holding company Diageo, based in London.
The Rumple Minze peppermint liquor has a strong candy-cane taste, and it has a high alcohol content at 50% alcohol by volume, (100 proof), compared to the 40% (or 80 proof) of most liquors. It is commonly served chilled, straight up (in some cases as a digestif) or it can also be mixed to form various cocktails.
