He said his first order of decocanised cocoa leaf was seized at the border. I can see that discouraging trying again, esp when he's trying to make something others could reproduce.

He did find a pretty good substitute for the primary cocoa leaf ingredient though. Also, what he made was virtually indistinguishable in the taste tests. One person said that his tasted closer to the 2L of coke than the can of coke did, which suggests the final bit could just be carbonation level of the soda stream.

That was our theory in the office when we taste tested the various cokes. The favorite by far was kosher for Passover coke. At first we thought it was the sugar vs. HFCS, but bottled Mexican coke didn’t fare as well — blind most people thought Coke Zero (which is my favorite coke) was Mexican Coke.

My theory was that the carbonation was perfect and the product was fresher, as the bottler requires rabbinical supervision and they probably make it for a limited run.

There is essentially zero chemical difference whatsoever in sugar vs corn syrup coke. sucrose disassociates in the presence of an acid into glucose+fructose simple sugars. Just being carbonated will disassociate the sucrose.
