The old fashioned phosphate soda recipes are from the 1950s, and earlier. Soda fountain beverages called "Phosphates," or "Acids," received their unusual name from the acid phosphate that was added to the beverage to enhance its taste and quantity of fizz.
Orange, cherry, lemon, lime (called a Green River), grape, vanilla, and egg phosphates were the most popular flavor choices, though some of the fancier, pricier phosphate beverages combined several flavors of fountain syrup and often a garnish of fruit to attract thirsty buyers. All are deliciously refreshing!
The Dispenser's Formulary or Soda Water Guide (1915)
This refreshing drink is so universally dispensed that a phosphate soda recipe is hardly necessary here, but it might be mentioned that a little orange syrup in a mineral-water glass, a little acid phosphate squirted into it, carbonated water from the coarse stream enough to nearly fill the glass, and cracked ice, or not, as the occasion or the drinker may require, the whole well stirred with a spoon, constitutes this most popular, perhaps, of all orange drinks.

To make genuine phosphate sodas, you will need a bottle of acid phosphate. "Acid phosphate" is NOT the same as phosphoric acid. It's a phosphoric acid that's buffered by specific mineral salts to help it maintain the proper level of acidity.
DO NOT substitute phosphoric acid, as it can be extremely dangerous to your health!
Acid Phosphate is very hard to find now, but there is one online source that I can highly recommend. The Prairie Moon Company carries an Acid Phosphate solution.

Prairie Moon also offers a variety of traditional fountain syrup flavors that can be used with the Acid Phosphate for an authentic soda parlor experience.
If you're at all impatient to experience a phosphate-like taste, you can easily do so by adding a "pinch of citric acid" when the phosphate soda recipe calls for a dash of acid phosphate. A "dash" consisted of just a few drops of the acid dispensed by the soda jerk from a glass shaker bottle kept handy.
An orange or cherry phosphate will taste just fine using citric acid. Actually, some of the old fashioned pharmacies used citric acid exclusively in their fountain beverages. You can purchase food-grade citric acid at most drug stores and some grocery stores, where it's often kept with the jelly and jam making supplies.
There was once a popular saying among the old time soda fountain operators that
"Drinks may come and drinks may go but the Orange Phosphate goes on
Well, it didn't go on forever nor did the equally delicious cherry phosphate or grape phosphate, but the popularity of these unique sodas did go well into the 1950s, until a greater variety of soft drinks came on the market and traditional soda fountains went into a steady decline.
Order a bottle of acid phosphate and a selection of your favorite fountain syrup flavors from the Prairie Moon Company (see link below), and enjoy trying these authentic phosphate soda recipes. Relive the days of the village soda fountain!
You might have heard that health experts are now trying to convince beverage bottlers to stop using phosphoric acid in their soda recipes since heavy consumption of soft drinks containing it may lead to lower calcium levels in the body and increase your chances of osteoporosis. That's because phosphate in the bloodstream tends to leach calcium from bone tissue.
Phosphoric acid is still used as a significant ingredient in most colas, root beers, and other dark-colored commercial soft drinks whereas most light-colored soft drinks use citric acid instead. You can find out which acid is used by reading the list of ingredients on the beverage container.
For health reasons, some people now avoid bottled soft drinks that contain phosphoric acids, choosing those that use citric acid instead. If you have been diagnosed with osteoporosis, or if you’re a pregnant mother, you should play it safe and avoid consuming phosphates. Simply substitute a pinch of citric acid in the phosphate soda recipes.
Remember, moderation in all things, even when it comes to phosphate soda recipes.
