Contrary to what one might think, these wind turbines are not used to generate energy. Called “wind towers” in the middle, they are particularly effective in protecting the buds (or fruits) against spring and autumn frosts.
From their height of 12 meters, these posts fitted with a propeller push down to the ground the warmer air located above. Thanks to them, a few degrees are gained on the plots swept by the wind. With the heat of the past few weeks, some buds have started to swell.
With colder temperatures expected, many winegrowers will certainly choose to activate their wind towers in order to limit the risk of damaging the buds!
