Whiskey Sour Letterbox Cocktail

A smooth and zesty Whiskey Sour made with whiskey, sugar syrup, lemon juice and bitters for a classic cocktail with a sharp citrus edge. At 16% ABV, it’s rich, balanced and refreshing, with the warmth of whiskey softened by a touch of sweetness and lifted by fresh lemon. The bitters add depth, while the frothy finish gives it that proper cocktail-bar feel. Best served chilled in a short glass or coupe glass for a smooth, frothy serve.
