This ultra-easy cocktail is mixed using just two ingredients: vodka and grapefruit juice.

Fill a rocks glass with ice cubes, add 2 ounces of premium vodka and 5 ounces of grapefruit juice (bonus points for freshly squeezed).

Garnish with grapefruit peel and serve.

Add a 1/2 ounce of rosemary syrup and a sprig of rosemary if you so desire.
