For shoppers in the UK, the freshest extra virgin olive oil is usually linked to the harvest season in the Northern Hemisphere rather than the calendar year printed on the front of a bottle. This guide explains when olives are typically harvested in Spain, Italy, Greece and other producing regions, when new-season oil may reach UK shelves, and how to assess harvest dates, packaging, storage and remaining shelf life before you buy.
Overview
Olives are generally harvested once a year, with timing varying according to country, latitude, altitude, weather, olive variety and the style of oil a producer wants to make. In broad terms, harvesting in Mediterranean-producing countries begins in early autumn and can continue into winter. Early-picked olives tend to produce smaller volumes with a greener, more bitter or peppery profile, while later-picked olives may offer a softer, riper character. Harvest timing alone does not determine quality, but it is useful context when comparing fresh extra virgin olive oil.
The UK does not have one universal “new season” date. Bottles from different origins arrive at different times, and the gap between harvesting, milling, bottling, export and retail can vary. A recently harvested oil may reach UK retailers from late autumn onwards, while oils from later harvests may appear during winter or the following spring. Availability is also affected by the producer, importer, bottle size and retailer stock rotation.
Use the calendar below as a planning tool, not a guarantee. Harvest windows overlap, and a well-made oil from a previous season can still be a sensible purchase if it has been protected from heat, light and oxygen and has a suitable best-before date.
| Origin or region | Typical harvest period | Possible UK arrival window | Label wording to look for | Useful bottle size |
|---|---|---|---|---|
| Spain | Often October to January, depending on region and variety | Late autumn through spring | Harvest year, crop year, or an estate harvest statement | 500ml for tasting; 750ml to 1 litre for regular use |
| Italy | Often October to December, with regional variation | Late autumn through spring | Raccolto, harvest year, or production-season information | 250ml to 500ml when buying a delicate, limited-release oil |
| Greece | Often October to January | Winter through spring | Harvest date or harvest season, sometimes with region or estate details | 500ml for finishing and dipping; larger tins for everyday cooking |
| Portugal and other Mediterranean origins | Usually autumn into winter | Winter through spring, depending on supply chain | Harvest season, crop year, origin and producer information | Choose a size you can use while the oil is still at its best |
What to track
1. The harvest date or crop year
A harvest date tells you when the olives were picked, which is more useful for assessing freshness than a vague front-of-pack phrase such as “premium” or “traditional”. Some producers print a specific month or date; others show a crop year or season. If no harvest information is available, check the best-before date and producer details, then consider contacting the retailer or producer if freshness is important to your purchase.
Do not confuse the harvest date with the bottling date. Oil may be bottled later, and the two dates answer different questions: harvest information indicates when the olives were picked, while bottling information indicates when the finished oil was packaged.
2. The best-before date and remaining shelf life
Extra virgin olive oil is best treated as a fresh agricultural product. It does not improve with age, so compare the best-before date with the amount you expect to use. A large container is not automatically better value if it will remain open for many months. For a household that uses oil mainly as a finishing ingredient, a 250ml or 500ml bottle may protect flavour and reduce waste. A larger tin or bag-in-box format can make sense for frequent cooks, provided it is stored correctly.
3. The container and shop conditions
Light, heat and air gradually affect olive oil. Look for dark glass, a tin or another package designed to limit light exposure. Clear glass is not proof of poor oil, but it offers less protection once the bottle is displayed or stored in bright conditions. Avoid bottles that appear dusty, warm, sunlit or placed beside heat-producing equipment. For a detailed comparison of formats, see our guide to glass, tin and bag-in-box olive oil packaging.
4. Origin, traceability and intended use
Country of origin can help you anticipate flavour, but it is not a quality ranking. A robust Greek or Spanish oil may suit grilled vegetables and bread, while a gentler Italian oil may work well with fish or salads; individual producer and harvest choices matter more than national stereotypes. For a broader comparison, read our guide to Italian, Greek and Spanish olive oil.
Also decide whether you want a peppery oil for dipping and finishing, or a balanced everyday oil for dressings, roasting and cooking. A fresh harvest is most valuable when its flavour matches the job and the bottle will be used promptly.
Cadence and checkpoints
Use a simple seasonal routine rather than waiting for a particular “best” month.
- September to October: Watch for harvest announcements and early-pick releases, especially from producers that publish detailed crop information. Availability in the UK may still be limited.
- November to January: Check specialist retailers and producer listings for newly arrived oils. Compare harvest season, origin, format and expected use rather than choosing on date alone.
- February to April: Later-harvest oils and additional shipments may become available. Review bottles already in your cupboard and use older opened oils before opening a special new-season bottle.
- May to August: Focus on storage and stock rotation. Keep oils away from windows, cookers and radiators, and buy only the quantity you can use during the remaining shelf life.
When buying online, inspect product photography and the written listing for harvest information, but remember that an image may not show the exact batch currently being dispatched. If the listing does not state a harvest date, ask the retailer what information is available before paying a premium for a supposedly fresh release.
How to interpret changes
A new harvest is a useful opportunity to compare flavour, but it is not a guarantee of superior oil. Taste can vary between years because of weather, ripeness at picking, milling decisions and storage after bottling. A newer bottle that has been exposed to heat or light may be less appealing than an older bottle that has been handled carefully.
Look for positive sensory signs when you open the bottle: fresh fruitiness, appropriate bitterness and a clean, lively finish. Depending on the variety and picking stage, the oil may smell like green leaves, herbs, tomato, almond or ripe fruit. Musty, stale, waxy or rancid notes suggest the oil is no longer at its best. Our olive oil tasting guide can help you compare bitterness, fruitiness and pepperiness at home.
“Cold pressed” may describe a production method, but it does not replace checking harvest information, origin, packaging and freshness. Similarly, “single estate” and “organic” can be meaningful buying preferences without proving that one oil will suit every recipe. Use the full label and your intended use to make the decision.
When to revisit
Revisit this harvest calendar at the start of autumn, when producers begin discussing the next crop, and again between January and spring, when more new-season oils may reach UK retailers. Retail listings, available bottle sizes and batch information can change during the season, so treat each purchase as a fresh check rather than relying on last year’s notes.
Before you buy, run through this checklist:
- Is the product clearly labelled extra virgin olive oil, and does it state an origin?
- Is a harvest date, harvest season or crop year provided?
- How much shelf life remains, and can you use the bottle within that period?
- Has the retailer stored it away from strong light and heat?
- Is the container suitable for the amount and speed at which you cook?
- Does the flavour style suit salads, dipping, finishing or everyday cooking?
Once opened, close the cap promptly and store the bottle in a cool, dark cupboard. Rotate older bottles first, label the opening date if helpful, and buy the next harvest when you are ready to use it—not simply because it is newer.
