Is this an AI response? coca-cola was replicated by one guy and confirmed in blind taste test by several other people, no magical machinery needed to make it once you know the ingredients.
What about quality? That has nothing to do with it.
Of course they're trying to be the better coke, that's why they tried making coke with the same color with more sugar and made the flavors stronger.
The “machinery” being the marketing, distribution, and general scale, not the physical vats used to mix it.
Even if you could replicate the exact flavor, you’d still need to do it at scale and get it into stores and convince people to buy it.
As to “just make it yourself”, everyone can make a sandwich, Jersey Mike’s and several other sandwich shops exist successfully.
Coca-Cola is the only company that can legally import and process raw coca leaves into a flavoring agent. It’s literally impossible to duplicate their exact recipe.
