Frost damage

Sad to hear reports of widespread frost damage to vines all over France and Italy on Tuesday and Wednesday nights. Temperatures plummeted to -6ºC in Chablis and the Jura for example. And at a time when vines have begun to bud and the leaves unfurl. The result, of course, is damage to these buds which will not produce grapes this year. No grapes means no money for the winemaker. And in some regions this is two years on a row. I was in the Loire at this time last year and saw the damage it can do for myself, some vignerons losing whole vineyards.

Two weapons have been deployed by some vignerons. Firstly, impressive photos from Burgundy and Chablis where, perhaps more wealthy, vignerons used fires amongst the vines to try to keep temperatures higher.

The other tactic, more counter intuitive, is too spray the vines with water so that the buds and leaves are immediately covered in ice and this protects them from further damage.

Large scale producers such as Roederer in Champagne are reporting losses of 10-20% of their vines for the year. Some smaller scale winemakers will have lost proportionally much more. I can only sympathise. Let’s hope things turn better for them soon.

I have seen some photos of the Languedoc being hit too.

It appears that hail also struck some areas last night too. The frost risk will last until Saturday.
