The works from May to August
The purpose of this step is to eliminate unecessary young plants and promote fruiting twigs.
Sometimes it is even necessary to remove excess buds (fruting disbudding).
It requires 120 hours work per hectar and from mid-May to beginning of July. It is done in two steps.
The vegetation is oriented upwards to benefit from the light. The operation is carried out with wires before the flowers. These wires are placed above the stocks. Fruiting strands can be attached, thus preventing them from falling to the ground.
This consists in placing staples after the foliage has been well distributed on order to hang the vine strands on the levator wires in the high position (rowsare about 1,20m high).
The purpose of lifting and trellising is to promote photosynthetic activity through a good aeration of the foliage that limits moisture of the clusters, thus fighting the development of botrytis (see page of definitions)
The correct distribution of sugars (synthesize by leaves) between the plant and the fruit is a major condition of the quality of the grapes.
This period from July until the harvest represents about 60 hours per hectar and is essential in order to cut off the unecessary branches that always seek to ascend towards the light of the sky by risking of depriving the clusters of their vitality.
