Wine gets better with time. Olive oil never does. It is a fruit juice — the juice of a fresh olive, pressed once — and like every fresh juice, it is best the day it is made and slowly less itself every day after.
That single fact is why one line on the label matters more than everything else printed there: not the best-before date, not the bottling date. The harvest date — when the olives came off the tree.
Two Dates, Only One of Them Honest
The best-before date sounds like a promise. It is closer to a guess the seller is allowed to make. Producers set it themselves, typically eighteen months to two years from bottling — and bottling can happen many months after harvest. Oil pressed in November, tanked until the following autumn, and bottled then can carry a perfectly valid best-before date two years out. The olives were picked nearly three years before you pour.
The harvest date answers the question you actually have: how long ago was this a fruit? From harvest, well-stored extra virgin holds real quality for roughly twelve to eighteen months — brighter at six months than at sixteen. Every week of that window, you would rather know about.
Best-before dates are set by the seller. Harvest dates are set by the tree.
What the Fade Tastes Like
Fresh extra virgin is green and vivid: cut grass, green almond, tomato leaf, a bitter edge, a peppery finish. As months pass, the aromatics soften and flatten, the bitterness and pepper recede, and eventually the oil drifts toward the vague, waxy neutrality that most people think olive oil is supposed to taste like. Nothing has gone rotten. The life has simply left.
And it is not only flavor. The compounds that fade first — the polyphenols, the antioxidants — are the same ones behind the health case for the oil. Freshness is not a luxury preference. It is the substance of the thing.
How to Use the Date
Peak territory. The oil is close to the mill and everything it promises is still there.
Still good if well made and well stored. Softer than its youth; use it generously rather than saving it.
Ask yourself what a producer gains by not telling you. Then reach for a bottle that tells you.
One geography note that helps at the shelf: the Northern Hemisphere harvests in autumn — Greece, Italy, Spain press roughly October through December. The Southern Hemisphere — Australia, Chile, Argentina — presses in their autumn, our spring. In an American summer, the freshest oil in the shop may well be from below the equator, and a November-harvest Greek oil is midway through its year. The date lets you do that math instead of guessing.
Our own rhythm is the simple one: picked in November, milled within hours, on a ship not long after. The date on the tin is the date on the trees' calendar. When the new pressing lands each winter, the old one stops being what we sell — which is why there is a waitlist, and why it hears first.
12–18 months — the window of real quality for well-stored extra virgin, counted from harvest, not bottling.
October–December — the Northern Hemisphere pressing season, Greece included.
Up to 2 years — the best-before cushion a producer can print from bottling, regardless of harvest age.
First to fade — aromatics, then bitterness and pepper, then polyphenols. Flat oil is old oil.
