Ensure Authenticity
There are plenty of bottles out there posing as Italian olive oils, however, that is not always the case. Be sure your oil is DOP (Denominazione di Origine Protetta) certified. This signifies that from start to finish, by law, the product has gone through an extensive quality process that includes pressing, bottling and shipping out of Italy. While observing the bottle, look to see which region the olives come from and that they all are from the same one. Also, although it's not an indicator of authenticity, producers know that any light entering the bottle can cause the oil to photo-oxidize and taste bitter. So go for darker.
