I am ok with “imitations” that follow the same process but it gets really specific when it’s about the weather in a specific region making. You can reproduce the same environment and bacterias but to get it just like the original it’s probably a lot more difficult than to make the product in its traditional “authentic” setting. Unless it allows increased production it’s difficult to see how it would be commercially viable. So in practice they cut corners and it’s not as good as the real one.
