We love the hard seltzer phenomenon, we just didn't care for what was out there on the market. So, we made the best hard seltzer in the world. Fountain Hard Seltzer is made with a gluten-free fermented alcohol base, a touch of premium all-natural flavours, and sparkling water. With only 93 calories, natural ingredients, and 5% ABV, Fountain comes in 4 fresh fruit flavours: Passionfruit, Raspberry, Mango and Watermelon.
