2025 UK record breaking harvest figures released

As the new growing season is now fully underway, vineyards like us, across the UK, are reflecting on an extraordinary milestone: the 2025 grape harvest, which was confirmed as one of the most impressive in recent British viticultural history.
For producers like us, these national results set a powerful tone for this year, highlighting both the potential and the resilience of UK winegrowing.
Production surged
According to WineGB, UK production surged by 39%, when compared to 2024, driven by a rare combination of early warm weather, a dry spring and four separate heatwaves in June and July across the south of the country. These conditions created the earliest and ripest harvest ever recorded in the British Isles.
Alcohol levels rose
Quality indicators also point to exceptional fruit maturity. Growing Degree Days reached 1051, notably higher than the five‑year average of 1008, while average potential alcohol levels rose to 10.48%, up from the long‑term figure of 9.47%. Meanwhile, tartaric acid levels fell slightly to 10.22 g/l, supporting balanced acidity in the final wines produced.
Several key grape varieties outperformed expectations too:
- Bacchus, which we grow, reached an impressive 9.5 tonnes per hectare (vs. a 6.75 t/ha five‑year average).
- Solaris climbed to 7.2 t/ha, up from 4.20 t/ha.
- Pinot Noir, a cornerstone of many sparkling and still wines, increased to 5.90 t/ha compared to a 5.79 t/ha average.
Scale of the year’s results
Alongside WineGB’s findings, the Food Standards Agency confirmed the scale of the year’s results, reporting 124,377 hectolitres of wine produced nationwide – equivalent to more than 16.5 million bottles, a remarkable 55% rise on the previous year.
Successful year
For us, these figures reflect not just a successful year for UK viticulture, which should be heartily celebrated, but are a powerful, positive reminder of what our changing climate can do that’s good and what our ongoing craft and commitment can achieve.
While temperatures are up and this has a negative environmental impact too, these figures mean wines can be made and purchased in the UK, reducing the need to import them and the use of resources including fossil fuels to do this.
With predictions of another good year weather wise, we look ahead to 2026 with boundless optimism and no small measure of excitement for what is to come. Will it be record-breaking again?
