Pruning is a key stage in their management.
It is physically arduous for the winegrower because it takes place in the winter cold, but it helps determine the vigor and the shape of the plants. The winegrower chooses the number of buds to leave on the wood, and in doing so, limits the yield from the plot in order to obtain higher quality fruit.
During the winter rest, the buds on the vine are covered by two brownish scales. This protects them from frost, unless the temperature falls exceptionally low, below 15°C, for several days.
