One Day in Rio: A Split-Base Summer Cocktail

One Day in Rio

A summery drink brightened with a tangy gastrique.

Forget the beaches of Brazil—as the summer heat beats down, drink maker Stephanie Teslar keeps cool with this breezy mix of cachaça, blanco tequila, and watermelon gastrique. “I love adding vinegar to cocktails,” Teslar says. “It really surprises the palate.”


  • 3/4 oz. cachaça
  • 3/4 oz. blanco tequila
  • 1 oz. watermelon gastrique
  • 3/4 oz. fresh lime juice
  • 12 leaves of fresh tarragon
  • 1 oz. club soda
  • Tools:muddler, shaker, strainer
  • Glass:double rocks
  • Garnish:fresh tarragon sprig


Gently muddle the tarragon and gastrique in a shaker, then add the remaining ingredients and shake with ice. Strain into a glass filled with ice cubes, top with soda, and garnish.

Watermelon GastriqueSimmer 1 cup of white wine vinegar, 4 cups of white sugar, and 1 cup of fresh, strained watermelon juice over medium-low heat for 10–15 minutes, or until reduced by one quarter. Cool before transferring into a jar. Cover and keep refrigerated for up to 2 weeks. Makes enough for about a dozen cocktails.
