The very high density of plantation in our vineyard (10,000 plants per hectare) would quickly cause the vine shoots to overlap and tangle, if we didn't trellis the vines very carefully. The aim of trellising is firstly to enable us to pass freely through the rows, either on foot or by tractor, and especially to help expose the bunches to sunlight, which is crucial for optimal ripeness.

Trellising involves two successive operations: first of all, securing the branches in an upright position, using the movable iron wires, which are gradually adjusted upwards as the new shoots grow. This is followed by trimming, the second operation, when the tips of the shoots are trimmed by a mechanical device fixed below the high tractor which straddles the vines. It is thanks to this trellising that the great vineyards of Bordeaux have that grand, slightly severe look of the French-style garden. This special care taken in the way the vines look, not only demonstrates how rigorously the vines have been maintained but also reflects the pride, even the love, in the hearts of those who have tended them.
