Vertical Shoot Positioned
Also known as VSP, the Vertical Shoot Positioned method is a cane trained trellis system.
The role of Vertical Shoot Positioned Trellises
It is very common in New Zealand, but is used in wine regions throughout the world. VSP is very similar to the Guyot Double system, but it differs in that four canes instead of two are trained horizontally from the previous season.
Two canes run parallel in either direction with one several inches above the other on both sides. All of the new season’s canes are trained upwards with wires. ape bunches grow from 36 to 48 inches above the ground.
The VSP system is very easy to mechanically harvest. Low-yielding vineyards thrive using the VSP trellis system and produce very good, but rarely the best wines. A drawback to the system is that it tends to create a lot of shade for lower-lying fruit.
These vineyards look like well maintained hedges. The trunk is usually kept short, and the vines and rows are spaced close together. It is widely used in California, Burgundy and Bordeaux.
