No cauldron—or blender—required! The Witches Brew Slushie Mix is the perfect potion for your next gathering. Simply pour two bottles of prosecco into the bag, pop it in the freezer, and in a few hours you’ll have a frosty, festive slushie ready to enjoy. Lightly bubbly, refreshing, and a little bit spooky, it’s the easiest way to serve up Halloween magic in a glass.
