Wine Production : Vine to Bottle - Vinum Vine

New World countries, including Australia and Chile. Two cordons are
trained in opposite directions along the bottom wire (which is
approximately 1 metre off the ground) and each of these will be
allowed perhaps ten or twelve spurs which are pruned. With the
replacement cane system, practised in New Zealand, there are four
canes, two in each direction, with one cane tied to the bottom wire
and another to the next wire, which is perhaps 15 cm higher.
Advantages of VSP training include reduced risk of fungal diseases,
as the vines are not close to the ground and the canopy is
not dense, resulting in less humidity within the canopy. The fruit is
contained in a compact zone, with the tips of the shoots higher.
Thus mechanisation, including mechanical harvesting, is facilitated.

4.3.2 Other training systems
There are many other training systems. Some have been used since
ancient times – these include the use of pergolas and vines growing
