Grapefruit Kombucha Margarita

These days, you can pretty much order any flavor of margarita, from blood orange to jalapeño. Our personal favorite, however, is grapefruit—and we guarantee it will become yours, too. To create this festive cocktail, we combined tequila, lime juice, grapefruit juice, and simple syrup in a cocktail shaker, then poured it over ice and topped it with bubbly kombucha. To make simple syrup, combine equal parts water and sugar in a saucepan, bring to a boil, and cook, stirring occasionally, until the sugar is dissolved. Let cool before adding to the cocktail shaker so that it doesn't melt the ice.
