You can't go too wrong with a classic margarita, so this variation is simply an improvement - especially if you use a quality mezcal like Sombra Espadin. The sweet-tartness of freshly squeezed grapefruit juice is balanced and heightened by the piney, herbal notes of fresh rosemary. This woodsy and refreshing drink is perfect for summit sipping. 

Single Serving/Firelight 750 To-Go

Add the rosemary and agave nectar to an empty cocktail shaker (no ice) and muddle until the rosemary becomes fragrant. Add the tequila, grapefruit and lime juices, and ice to the shaker. Shake vigorously for 10-15 seconds and double strain (pour over a mesh strainer) into your ice-filled flask.
