Shake ingredients together with ice-cubes, strain, and offer up in the martini glass. Garnish with a light spread of good coffee grounds.
For the iced coffee concentrate:
Make use of a medium or even light roasting coffee. Grind one lb of coffee coarse. Inside a larger glass pitcher, combine coffee and nine mugs of cold drinking water. Allow coffee in order to soak and make for 18-24 hrs. Filter the focus by flowing the mixture via cheesecloth into an additional vessel. Refrigerate. Focus can be saved and used for as much as two weeks.
