Global News published this video item, entitled “Chablis winemakers fear destructive spring frosts may become regular occurrence” – below is their description.
For winemaker Thomas Ventoura, the spring frost that has hit the French region of Yonne, where the Chablis Grand Cru is made, the weekend had a bitter taste of déjà vu.
Like last year, at the same time, he and his colleagues had to deploy hundreds of oil lamps across the vineyards before daybreak to warm the vines and prevent the destruction of already well-developed shoots by temperatures below freezing.
Another tactic is to spray the wines with water, which then freezes and forms a protective coating around the plants to shield the vulnerable buds from even lower air temperatures.
Chablis is a very dry white wine that is produced only in the Yonne region of Burgundy due to the area’s specific climate. But volumes could now be under pressure as the emergence of mild weather early in the year followed by a spring frost, previously unusual, looks to becoming a recurrent trend.
The change in weather pattern is also pushing up his insurance coverage for loss of harvest, he added. In Yonne, two-thirds of the harvest was destroyed as a result of the frost last year, according to the farm ministry.
Winemakers were starting to join forces to invest in new tools, such as heating cables, to help mitigate the effects of such frosts, she said. However, many in the industry are still reluctant to face up to the fact that the impact of climate change could be long-lasting, Civet said.
