I look for the D.O.P and&#x2F;or organic farming mark, along with a production date, a best before date, and the region of Italy.  I&#x27;m pretty sure it&#x27;s ok, and it isn&#x27;t cheap.<p>I&#x27;ve heard that the best way to understand the olive oil business is to consider the fact (needs citation) that Italy exports twice as much oil as it produces.<p>Did your business work out?  What happened?  We bought a very nice AOC olive oil from Aix-en-Provence once.
