What are Bitters?
Bitters are seasoning, the salt and pepper of cocktails. They are not necessarily bitter and should not be confused with the Italian aperitifs, like Campari, that are sometimes referred to as bitters and actually do have a bitter taste. Cocktail bitters are used sparingly, only a few drops per drink, and vary in flavor profile; they generally run from 35% to 45% alcohol, though some have much less than that. Recently, with the rise of mixology, there has been a proliferation of new and interesting bitters on the shelves of liquor stores and bars.
