I always say yes, because some folks just don't drink alcohol and I get it! This cocktail will be a little harder to emulate without the gin, however these are my thoughts on a mocktail. Use the blueberry syrup on the bottom, maybe 3 oz instead of 2 oz. Use your favorite mixer or even a good lemonade for the middle and top with a blue soda or sports drink, if you want to stick with a red, white and blue look! If not, just top with ginger beer (non-alcoholic).
