Waterloo Watermelon Sparkling Water is familiar and fantastic. This flavored sparkling water is made with a blend of juicy notes and a just-right watermelon twist for the perfectly balanced flavor of summer all year long. Our inspiration came from perfectly ripe, fresh, juicy center-cut watermelon chunks. When our early recipes were a bit too hard-candy forward, we removed the rind notes and added a hint of citrus to re-balance the sweetness... and found perfection.
