Just water, zillions of tiny bubbles, and great taste! The Crowley family has been crafting Polar Seltzer with these same ingredients since 1882. That’s 138 years to perfect what their great-great-grandfather called the world’s best-tasting bubble recipe. Polar works hard to keep things uncomplicated, refreshing and endlessly creative. Take a sip of this delicious Black Cherry flavoured seltzer, and try for yourself! Calorie-Free Sodium-Free Gluten-Free Vegan Kosher Imported from the USA.
