Soda Fountain Phosphate

June 6, 2018

Phosphates were carbonated beverages made-from-scratch by the "soda jerk" using carbonated soda water, flavored syrups and phosphoric acid, an ingredient still used today in many brands of soda-pop including Coke. Popular flavors included cherry, lime (usually called a green river), chocolate and vanilla.

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, The Prairie Moon Company carries an Acid Phosphate and over 70 flavored syrup concentrates.
