The density of plantation in our vineyard (5,000 plants per hectare) would lead very rapidly to an impossible tangling of the branches, without a good trellising.
Our goals are to optimize the ratio square meter canopy vs fruit yield, and on the meantime allow the free circulation between the rows, for a better mechanization.
Chateau Nine Peaks uses the Vertical Shoot Position (VSP) System where the vine shoots are trained upward in a vertical, narrow curtain with the fruiting zone below.
