Sent to me from Real Simple, love this site. A big batch cocktail that’s finished with a sparkling splash. The beverage has just a few ingredients, but is very well balanced. The mint, lime, and lemon are a great pairing for floral, bracing champagne. And the gin packs a pleasant slightly bitter punch. We won’t tell anyone if you decide to use your favorite Prosecco or other sparkling wine instead of true champagne. You can make the mint simple syrup up to a week ahead of time and refrigerate it in an airtight container. A couple hours before you serve it, stir the gin and citrus juices together with the mint syrup. Top the punch with champagne and garnishes at the very last minute.
