OIV world wine production 2026: what to expect in November
The OIV's first estimate of world wine production for 2026 isn't out yet. Here's the number it will be measured against, what we already know, and what to look for when it lands.
The OIV hasn't published its 2026 world wine production estimate yet. Last year's first estimate came out on 12 November 2025, so November is the likely month, though I found no announced date.[1] When it arrives, you'll want one benchmark in hand: 228 to 235 million hectolitres for 2025.[1]
Is the OIV's 2026 world wine production estimate out?
Not as of 29 October 2026. The OIV press page lists only October items, and none is a production estimate.[4] The figure will come from the World Wine Production Outlook, an annual report with preliminary numbers for the current year's volume.[3]
So this isn't a report on a number. It's a guide to reading the number before it lands.
What did the OIV say about 2025?
In November 2025 the OIV put world production at 228 to 235 million hectolitres, with a midpoint of 232. That was about 3% above a historically low 2024 and about 7% below the five-year average.[1]
In May 2026 the OIV's full report on the sector called 2025 a low global vintage, with climate events hitting both hemispheres.[2] Trade fell in both volume and value in 2025, because of tariff policies and economic factors. Consumption has been sliding for several years too.[2]
| Benchmark | Figure | Source |
|---|---|---|
| OIV first estimate, world 2025 (12 November 2025) | 228 to 235 million hl, midpoint 232 | [1] |
| Same estimate against 2024 and the five-year average | about +3% and about -7% | [1] |
| EU production, 2024-25 low | 143 million hl, 10.4% below the previous five-year average | [7] |
| EU production, 2020-21 peak | 170 million hl | [7] |
| France 2026, Agreste at 1 September | almost 34 million hl, about -6% on 2025, about -17% on 2021-2025 | [5] |
What do we already know about 2026?
France gives the clearest picture. Agreste's September estimate is almost 34 million hectolitres, about 6% below 2025 and about 17% below the 2021-2025 average. Two things drove it: a smaller area in production, and yields hurt by drought and summer heatwaves.[5]
But the damage isn't even. On 7 October the regional office for Occitanie put Languedoc-Roussillon at 10.59 million hectolitres, up 19.6% on a very small 2025.[6] The whole Occitanie harvest is up 18% on 2025 and 1.5% above its own five-year average.[6] Across France, some regions are down sharply while others recover from the weak 2025 harvest.[5]
That's the point to carry into November. One country's small crop doesn't set the world total, and inside a country the picture splits by region. I'm leaving out Italian and Spanish 2026 figures. The ones I found came from trade reports that disagree with each other, and I couldn't open a primary document.
What should you check when the estimate lands?
- The range, not just the midpoint. Last year's spread was seven million hectolitres.[1] A wide range means the OIV itself is unsure.
- The comparison it chooses. Against 2025, a third low year looks like a recovery. Against the five-year average, it may not. Last year's release used both, and the gap between them was about 10 points.[1]
- Which side of the equator drives the change. Climate events in both hemispheres marked 2025.[2] See whether 2026 repeats that or tilts one way.
- What the OIV says about demand. Smaller harvests only tighten a market if people keep drinking and trading at the same pace. For 2025, consumption and trade both fell.[2]
What does this mean if you're planning a wine master's?
If you're heading for export, brand or business development work, the production number is an input, not the story. A small crop can mean higher prices, thinner volumes for exporters, or nothing much if demand is falling. Reading that properly is a skill. You can't get it from a headline.
The MSc in Wine and Beverage Business Management covers that ground, in modules such as Global Wine Markets and Business Strategy and Global Beverage Industry Dynamics and Innovations. You'll also earn WSET Level 2, which is embedded in the programme. The graduate roles we cite are beverage portfolio consultant, brand manager, business development manager and export manager. The degree doesn't promise one of them. And if you want an internship, you can add one in the second semester, but it's optional.
The programme runs 12 months on the Lucerne campus: a taught semester, then a semester off campus for your research project. You can start in February 2027, August 2027 or November 2027. Every MSc costs CHF 41'700 all-inclusive.
What to do next
Read the OIV release when it appears and test it against the four checks above. If you're weighing a wine master's, start with the MSc Wine and Beverage Business Management page, check the full breakdown on the fees page, or send your questions to martin.wyler@bhms.ch.
