Origin & Story
The Mezcal Sour emerged alongside the wider mezcal boom in American craft cocktail bars during the 2010s. Bartenders discovered that mezcal's assertive smokiness paradoxically benefits from the sour format — the lemon juice's brightness and the egg white's softness create contrast that tames the spirit's intensity without blunting it, resulting in a balanced, complex drink.
