📜 History

Phosphates were the stars of American soda fountains from the 1870s through Prohibition. The secret ingredient—acid phosphate—added a pleasant tartness that made these drinks incredibly refreshing. During the dry years, soda fountains became social hubs, and phosphates were the sophisticated choice for those wanting something more complex than plain soda.
