Cut pink grapefruits in half and squeeze the juice into a fine-mesh sieve set over a large pitcher. Push down on the pulp in the sieve to release all of the juice.

Fill two Collins glasses with ice cubes. To each glass, add 3 ounces of vodka, 6 ounces of pink grapefruit juice and 1 teaspoon of agave nectar. Stir well, garnish with a lime wedge and serve. If you prefer your cocktail to be a little sweeter, add additional agave nectar.

Serve them up!
