When you pick up a bottle of olive oil, the first date many people look for is the "Best By" date. Unfortunately, that date doesn't tell you one of the most important facts: when the olives were actually harvested and the oil was produced.
A "Best By" date is usually calculated by adding a certain number of months to the bottling date. That means two bottles with the same Best By date could have been made from olives harvested at very different times.
Freshness matters because olive oil naturally loses some of its aroma, flavor, and beneficial antioxidants as it ages. While good storage helps preserve quality, nothing replaces knowing when the olives were harvested.
That's why many high-quality producers proudly print the harvest date on the bottle. It gives consumers a much clearer picture of the oil's freshness than a Best By date alone.
The bottom line: A Best By date tells you how long the producer expects the oil to remain at good quality. A harvest date tells you when the journey actually began. If you want the freshest extra virgin olive oil, always look for the harvest date whenever possible.
