Spring frost fighting

This month of April reminds us of the cool nights of April 2017, when the temperatures had been fatal for our vines.


These last 2 nights, the negative temperatures confronted us with a new episode of frost and threatened France vineyards. To protect against freezing, some solutions exists, but none guarantee total protection.

In Vilatte as in a large part of Libournais, we prepared  the day before, to posibly make a fire during the night.

Depending on the forecast temperature, humidity and down-wind, we distributed hay bales as best as possible along the vineyard plots. By monitoring the temperatures overnight, we finally decided to set some hay bales on fire in the coldest plots between 4 a.m. and 5 a.m. Heavy smoke carried by favorable winds raised a protective fog over the vines. It's this fog of smoke that keeps the cold above and the "warmth" below.

Depending on the forecast for temperature, humidity or even the direction of the wind, we distributed bales of hay as best as possible places along the vineyard plots. By monitoring the temperatures overnight, we finally decided to set some bales on fire in the colder plost between 1 a.m. and 5 a.m. Heavy fumes carried by favorable winds raised a protective fog over the vines. It was this bouillard of smoke that had the cold above and the "hot" below (at the level of the vines).

We were lucky that the conditions were right to successfully create smoke and protect the majority of our vines. 2 plots on which we did not intervene were partially impacted.

So we are comes out without too much "damage" and continue to hope for better weather for a beautyful season.
