The traditional aperol spritz calories are quite high, but we lightened up this homemade aperol spritz so that you can enjoy it without hurting your diet.We took the 350 calories cocktail, down to just 152 calories... But we did have to lower the amount of alcohol to do so, something I never like to do, but assure you, this is still a strong drink.This stunning happy hour cocktail recipe for spritz is light and refreshing, and doesn't need any shaking, stirring or fussing over. Just pour and serve!
