2 oz dark rum
2 oz light rum
2 oz Sea Salted Grapefruit & Agave Mixer
1/2 oz fresh lemon juice
4 oz Apple Cider
Fill a cocktail shaker with ice. Add dark rum, light rum, mixer, and lemon juice. Shake until well chilled, about 10 seconds. Divide evenly between 2 ice-filled highball glasses. Top each glass with 2 ounces cider, stir gently to combine, garnish with grapefruit peel if desired, and serve.
