And this is why the EU PDO is useful. If you have a product with such a designation, you know some of it's qualities. If i pick up feta, I know that it's made from sheep or goat milk, but if I buy Greek salad cheese or Feta-style, I have no such guarantees. Admittedly, some of the designations are a bit off, such as not being able to make Stilton cheese in the village of Stilton.
