You may know that sodas are dispensed in restaurants by mixing carbonated water with a concentrated syrup. And I got to thinking last night, what if you took the sweetener out of the syrup and put it in the carbonated water instead? And then, what if the fountain was hooked up to two different carbonated waters (one with high fructose corn syrup in it and the other containing my preferred aspartame/acesulfame potassium blend)? And finally, at the fountain, the customer could indicate whether they wanted the regular or diet version of a soda just by pressing a button or flipping a switch. In particular, it would allow diners to have the diet version of any regular soda being served at the restaurant, including examples that otherwise aren't available, such as:
- Diet Mug Root Beer. Today, restaurants that serve Pepsi products will offer Mug Root Beer but not Diet Mug Root Beer.
- Fanta Zero (orange soda). Most restaurants that serve Coke products offer Fanta orange soda--but I've never seen the "zero calorie" version of that particular soda (not at the supermarkets I shop at, anyway--Coke's web site says it does exist, though). My soda fountain idea would allow a diner to make one.
- Diet Dr. Pepper--I know that Arby's serves it but I don't know of any other restaurant that does.
- Here's a bonus for all those who actually liked the "new" Coke back in 1985: As I mentioned in a previous blog entry, if you took the aspartame out of Diet Coke and added high fructose corn syrup to it, you'll get that short-lived formula (also known as "Coke II"). So any restaurant serving Coke products could conceivably sell that particular formula using the unsweetened Diet Coke syrup/high fructose corn syrup-sweetened carbonated water mix.
