Crafted by Real Bartenders

Proof Syrup began at a craft cocktail bar we used to own in Georgia. We wanted to create Old Fashioned cocktails quickly and easily with authentic ingredients. Our journey began with the exploration and creation of a syrup containing the sugar, bitters, and citrus oils that give that classic cocktail its characteristic flavors. It was then time to try it out, and the verdict arrived quickly! Our customers loved it.
