Extreme drought and heatwaves have offered challenges for wine producers throughout Europe in 2022, from sustaining vine well being to issues about – and the impression of – wildfires.
Early harvests have been a characteristic of the classic and experiences emerged this week of information being damaged at some white wine-producing estates in Bordeaux.
Spain’s Caserío de Dueñas property in DO Rueda stated it started a document early harvest on 16 August this yr.
Whereas drought and warmth have put strain on yields in some areas, there was optimism about 2022 classic high quality.
‘In Rueda, our 21-year-old vines have coped properly with the warmth and we had been capable of assist the vegetation retain freshness by way of irrigation,’ stated Almudena Alberca MW, winemaking director at Entrecanales Domecq e Hijos, proprietor of Caserío de Dueñas, in August.
‘The areas of the vineyards that had been uncovered to extra sunshine have clearly ripened sooner than the shaded areas, resulting in uneven berry sizes, however the well being of the grapes is superb.’
Related experiences of wholesome grapes have come from producers in Champagne. In Italy, farming affiliation Coldiretti stated on 1 August that drought and warmth might minimize the nation’s 2022 wine manufacturing by 10%, however ‘an excellent [to] wonderful high quality yr is anticipated’ – even when a lot can change within the essential ripening interval.
Germany’s wine institute stated final week that harvest was ‘exceptionally early’ however classic high quality is promising. The sunny climate ‘provides hope for full-bodied and colour-intensive pink wines’, it stated, though ripening slowed on some youthful vines because of drought stress.
France’s agriculture ministry not too long ago forecast nationwide wine manufacturing to rise considerably on the frost-hit 2021 classic, however warned about drought’s unsure impression.
Samuel Guibert, co-owner and winemaker at Mas de Daumas Gassac in Languedoc, southern France, instructed Decanter in mid-August, ‘2022 is a really fascinating, uncommon classic’.
He noticed good winery circumstances as much as June, then virtually three months with out rain. He stated he anticipated ‘extra focus’ in fruit and a decrease yield than initially anticipated, however some latest ‘great rain’ had helped.

Fabien Teitgen, MD and winemaker at close by Château Smith-Haut-Lafitte additionally expressed optimism for the property’s 2022 classic when contacted by Decanter in August.
Irrigation in Bordeaux and drought’s impression on vineyards
Distinctive measures this yr allowed some Bordeaux appellations to irrigate vines, below strict circumstances.
It appears to be like like 2022 has been the ‘greatest water demand yr’ for Bordeaux vines prior to now 22 years, stated Gregory Gambetta, professor of viticulture at Bordeaux Sciences Agro and the Bordeaux Institute of Vine and Wine Science (ISVV), citing a colleague’s knowledge.
‘It’s necessary to keep in mind that the quantity of rain falling from the sky is simply half the equation. The opposite half is how scorching was it,’ stated Gambetta, who has a analysis concentrate on drought tolerance and local weather change adaptation.
‘When you’re getting much more warmth spikes, and we’re in Bordeaux…it will increase the water use of the vegetation it doesn’t matter what,’ he stated to Decanter in August, from California. ‘So the warmth performs an enormous position in it.’
For premium wine producers content material to crop at comparatively low yields, drought circumstances have the potential to enhance wine high quality. ‘You probably have a cropping system the place the fruit is actually protected and the temperatures aren’t that top, then it’s simply going to make issues higher,’ stated Gambetta.
Once more, although, it’s the coupling of temperature and drought that may complicate issues. Sunburn injury could be a difficulty, for instance.
Vintages are usually turning into riper, too, stated Gambetta. This may be helpful however it’s necessary for producers to take care of stability within the fruit.
In a spot like Bordeaux, larger flexibility in appellation guidelines could possibly be necessary for growers in future. Adapting to new circumstances may additionally require modifications in mindset.
Planting density is a key subject in Bordeaux, stated Gambetta. ‘One factor that’s actually clear is that should you lower the [planting] density of a winery it turns into extra drought resilient,’ he stated. ‘Every vine has entry to extra water, theoretically, as a result of it has much less competitors.’
For vines, early-season water deficits are a selected concern as a result of most progress occurs earlier within the season.
For now, that is much less of a difficulty in Bordeaux. ‘More often than not in Bordeaux you begin off with a full tank. It was solely three seasons prior to now 50 years in Bordeaux the soil wasn’t absolutely recharged,’ Gambetta stated.
Analysis is ongoing globally round drought’s impression on wine and vineyards. In Europe, as in different components of the world, growers are working to adapt.
At Spanish wine group Entrecanales Domecq e Hijos, Almudena Alberca MW stated not too long ago that sustainability efforts have included ‘replanting vineyards with drought-resistant rootstocks, lowering density with fewer vines/hectare and burying irrigation pipes to cut back water use by 30-40%’.
She additionally highlighted local weather instability, echoing scientific proof that excessive climate occasions have gotten extra frequent.
‘Over the previous 10 years, we’ve skilled very assorted circumstances in our vineyards – from heavy snowfall and a cool spring in 2021 to this yr’s drought and warmth,’ stated Alberca.
