Virginity? Never purchase olive oil that is not showing the expiry date. The expiry date of extra virgin olive oil is approximately 18 months from the bottling date. However, if olive oil is stored well, a good Extra Virgin should maintain its freshness for up to 24 months from the production date. We would recommend when purchasing olive oil calculate what you would use over a 3-month period, so you are always getting the oil as fresh as possible. Our extra virgin olive oil has the expiry date stamped on the bottle at the time of bottling and also has the lot number and a bar code for traceability of the olive oil.
