This simple-but-sophisticated, effervescent cocktail hinges on the classic French flavor of Crème de cassis (blackcurrant liqueur) and possesses a refreshing quality that makes it perfect for midsummer evenings. To create it, shake 3 ounces of Vodka 14 on ice and strain into a chilled martini glass. Add 2 ounces of organic cassis and a generous splash of Perrier sparkling mineral water, stir. Squeeze in a splash of lime and garnish with fresh lime wedge. Allez!
