Memorial Day weekend is the unofficial start of summer. That means your three-day weekend calls for backyard barbecues, pool hangs, and of course, fizzy drinks. Sip on the season’s sweet, sour, and fruity flavors in these delicious cocktails, including margaritas, sangria, and more. Plus, let kids join in on the holiday fun with slushies, flavor-infused lemonades, or other mocktails. Parents will probably want to give ’em a taste, too.
