The variety of methods for training vines are many and varied. The method employed is of far more importance than you may think - it is not simply a job of keeping the vines from dangling on the ground. Many dozens of different training techniques have been developed, some of which have been in use for centuries, such as gobelet, and some for just decades, such as Scott Henry and Smart Dyson. The different methods assist in controlling vigorous vines that produce too much foliage and not enough fruit, may increase exposure of the foliage to light, improve air movement through the leaf canopy and thus reduce the risk of rot, and they may facilitate mechanisation of pruning or harvesting.

Lyre

A development of the Geneva double curtain, the Lyre system was the work of Dr Alain Carbonneau, Professor of Viticulture at Montpellier. It came about in the 1980's, and its principle advantages are improvement to the canopy microclimate resulting in less shading of foliage and fruit. Like the GDC, the trunk is divided into two cordons, although at a lesser height, perhaps 1.0m. At this level the cordons are grown along the two parallel wires, but the fruiting canes are grown upward, rather than allowed to dangle down, producing a lyre shape when the row of vines is viewed end-on. Unlike the GDC, it is preferred for medium vigour vines. Although an obvious candidate for spur pruning, it may also be cane pruned.
