Fountain Applications

Fountain beverages are 87% water. The right filtration solution from Pentair Everpure® can consistently deliver that “right out of the bottle” taste, fizz and appeal your customers expect.

A fountain drink is typically five parts water to one part syrup (frozen carbonated beverage ratios vary), so around 87% water, and most are served with ice. Since ice is 100% water, that ratio only increases as ice melts in your beverage. Those numbers illustrate just how critical a role clean, high quality water plays in the final taste and smell of a fountain beverage. (And what many do not know is that water quality also affects the performance of delivery and dispensing systems, the balance of water to syrup and the quality of the carbonation).

Water contaminants are the most likely reason for off-tastes and odors in a fountain drink. Municipalities use chlorine or chloramines to disinfect central water supplies and those chemicals oxidize and break down sugars in water. Those reactions produce a range of different compounds that can negatively influence the taste of a beverage, and byproducts that can actually amplify a chlorine or ammonia-like taste. In addition, because free chlorine is a gas, it will dissipate along with the carbonation after a drink is poured, creating a “swimming pool” smell.

Other fountain beverage taste and odor problems caused by water contaminants include:

  • High total dissolved solids (TDS) can cause weak carbonation and lead to “soft” ice which melts quickly.
  • Organics such as the algae, molds and bacteria that naturally live in lake and river water sources can cause an “earthy” or “moldy” taste and odor, plus impact beverage color.
  • Tannins caused by decaying organic matter in surface water will often give beverages a yellowish tint; this is especially noticeable in clear lemon-lime drinks and iced teas.
  • "Rotten egg smell” that originates from hydrogen sulfide in water which is produced by bacteria in deep wells and in stagnant, low use water mains.

Foodservice operations may resort to adjusting the brix ratio to mask these off-taste and odor concerns which only increases syrup costs – an expensive fix which directly impacts profit.
