Tony's coffee held an Instagram contest to make the best coffee cocktail and this is my concoction! The Slowly Shirley. Tony's Cold Brew coffee, Barbados Rum, Kahlúa, Honey, Guava, Passion Fruit, Orange and Lime. Perfect for tiki-loving coffee addicts, this Tahitian coffee cocktail marries the islands of rum, tropical fruit and coffee into this scorpion style bowl drink which is served in a Chemex for two. The fruit flavors are in contrast to most coffee where java is the central component.
