Bottled only once a year in the spring, Fee Brothers' Whiskey Barrel Aged Bitters is sold as a limited edition bitters! Wonderfully spicy, rich yet non-alcoholic, it adds depth and complexity to cocktails. Whisky Barrel-Aged Bitters is used by craft-cocktail mixers to elevate classic drinks such as an Old Fashioned and a Manhattan, and can be added to Champagne Cocktails or a Hot Toddy.
