The winner? It's a toss-up. Raise a glass and make a toast. May the best team come out on top. (Oh, and by the way, if you choose to make these beverages, let's just say - more spirited - your secret's safe with us.)
Gently muddle 2 lemon slices, 2 Tbsp. simple syrup, and 1/2 tsp. root beer extract in a 10-oz. glass. Fill glass with crushed ice, and top with seltzer water or club soda. Gently stir. Garnish with a fresh lemon slice.
