4 cups Vodka (The higher quality the better)
1 ripe Grapefruit, sliced
In an air tight container, combine vodka and grapefruit slices. Seal the container tightly with a lid. Refrigerate for a minimum of 3 days. Do not let the grapefruit infuse for more than 1 week. Remove grapefruit. Serve over ice with sparkling water and mint garnish.
*If you do not like the bitterness of grapefruit pith, cut away the skin before slicing.
