That's not what's being contended. If you claim something about your product, that claim should be true, including it's geographical origin.

But that doesn't answer the question: does Cheddar cheese made in the village of Cheddar have some intrinsic, inimitable quality that can't be achieved outside of that village?

(And industrial producers do indeed plop down large factories in certain geographies so they can churn out large quantities of bland product, yet slap a geographical origin label on it, so it doesn't even protect against that).

As I mentioned milk changes taste dramatically across regions. Well it did before the current trend for homogenisation which has hurt the taste in every region.

So I would not be in the least surprised to find that the resulting cheeses are equally variant based on region.
