I love a spicy ginger beer ... that was too underdeveloped to make its presence known. Watermelon is a difficult flavor to turn into a seltzer, so I give Polar credit where credit is due.

Lime or grapefruit hard seltzer can add a much-needed tart kick to recipes like a spicy sangria. And for an ice-cold white wine watermelon sangria that doesn't get diluted, freeze watermelon hard ...
