It says right on the bottle, "premium blend". That should have been the very first clue this wasn't 100% olive oil.
> One might believe this means, for example, that it is a blend of various extra virgin oils from several regions
.. which I agree with. That would certainly be my first thought, especially after the word "premium". The phrase brings to mind an expert balancing of tastes and properties, not that it's been diluted 80% with a cheaper substitute they have carefully de-emphasized on the packaging. It's definitely misleading and I hope the book is thrown at them.
> and I hope the book is thrown at them
What book? Nothing here is illegal. Smarmy, absolutely, and I would buy this or anything else from that brand, but come on. "Throw the book at them!!1" doesn't really mean anything in this context.
How does it make that obvious? A blend of multiple different EVOOs is not uncommon.
> Nothing here is illegal.
Clearly they intended to deceive. I'm not certain it's illegal in this case, but deceptive labeling sometimes is.
