  • This Thursday, the Gironde Chamber of Agriculture published its first estimates on the damage caused by the frost episode on the Bordeaux vineyards.
  1. They show “a very great heterogeneity” in the department: the areas having suffered the most intense cold are the South-Gironde / Graves, the north Gironde and the Dordogne valley, with a damage rate sometimes higher than 80%.
  2. The authorities explain that “these estimates are provisional because the frost having occurred early (early April), we have to wait until May to see what the plant’s reaction will be after the current post-disaster physiological stress. “

We know a little more about the consequences of the frost episode on the Bordeaux vineyards. This Thursday, the Gironde Chamber of Agriculture published its first estimates on the damage. They show “a very great heterogeneity” in the department. The map of minimum temperatures recorded from April 6 to 12 indicates that the areas having suffered the most intense cold are the South-Gironde / Graves, the north Gironde and the Dordogne valley. The damage rates estimated to date roughly follow these gradients of minimum temperatures recorded on the territory, sometimes with a damage rate of over 80%.

“However, locally differences may have occurred as often in cases of frost with for example, in the same plot, very frozen low parts and others less. However, a difference of 1 or 2 ° C can sometimes save a harvest or destroy it ”, specifies the Chamber of Agriculture. The sensitivity of buds and twigs is also strongly dependent on their vegetative stage. The individual situations of wineries can be very diverse within the same municipality.

New estimates coming in May

In the stricken plots, hope is for the back buds which, if they have not been touched, could partially compensate for the loss of the main branches. Provided of course that other episodes of frost or hail do not occur. The authorities explain that “these estimates are provisional because the frost having occurred early (early April), we have to wait until May to see what the plant’s reaction will be after the current post-disaster physiological stress. “

A more precise estimate will be made from May. It will serve as a basis for discussions with the administration services for the mobilization of possible public aid (exemption from property tax, etc.). Also, in order to refine these estimates, winegrowers are invited to list their damage online.
