The vine must be pruned to produce more fruit than wood. Moreover, when it is not pruned, its grapes are small and acid. Therefore, they cannot produce a quality wine. Pruning the vine also consists in removing the useless wood of the previous year and in preparing the future harvest. Finally, the pruning allows to control the number and the volume of the bunches, and to limit the buds. It is essential to obtain an optimal harvest and maturation.
