I used a wine bottle to do the steeping. Lindz thought that making bitters would be a cool idea, and, by golly she was right. This bottle contains six feet of grapefruit zest (three grapefruits' worth), some grains of paradise, coriander, rosemary, ginger and Everclear.
It should be quite a potent cocktail sharpener. I added a bit of sugar syrup after straining it 24 hours later.
There is no end to the permutations of home made bitters.
