There was an interesting article in Consumer Reports a couple of months ago about this subject and they found many of the olive oils labeled as virgin or extra virgin were of much less quality. I can't recall all the specifics but Pompeii was one brand that was the real thing---I remember being surprised by that because I had always viewed it as a 'cheaper' quality. The only other specific brand I remember was Bertelli which is what I had been buying but it didn't pass the CR tests.
