Here is the recipe:

The ‘secret recipe’

Fluid extract of Coca 3 drams USP

Citric acid 3 oz

Caffeine 1oz

Sugar 30 (it is unclear from the markings what quantity is required)

Water 2.5 gal

Lime juice 2 pints 1 qrt

Vanilla 1oz

Caramel 1.5oz or more to colour

7X flavour (use 2oz of flavour to 5 gals syrup):

Alcohol 8oz

Orange oil 20 drops

Lemon oil 30 drops

Nutmeg oil 10 drops

Coriander 5 drops

Neroli 10 drops

Cinnamon 10 drops

What confuses me is the 8 oz of alcohol. This sounds like something a bartender would make.

Now all the world needs to know is how the “flavour” is made.

[johngrace]

Because that’s the syrup. Needs carbonated water.

Now if we could just get the Colonel’s KFC original recipe...

I wonder what the 7X flavor is?

Looks like the alcohol is used to help create or stabilize the flavoring emulsion. It probably has an effect on solubility.
