The Training of Vines
How a vine is trained depends on several different
factors. The vineyard, yield required and the climate
affect how a vine is trained. Some vines are trained low
so they will be aided by reflected heat and will escape
wind damage. Some are grown high to avoid reflected heat
from the ground. This can be beneficial because growing
vines high improves air circulation and reduces rotting
in humid climates. Presently there are three basic
systems for training vines.
The Bush system is a spur-pruned system that is popular
in warmer vineyard regions. These include Spain, south
France, the Rhone Valley, and Beaujolais. This system is
not appropriate for damp areas where rotting is a
concern because of the poor air circulation which
results from the vines being close to the ground. This
system is also not appropriate for areas which are
subject to spring frosts. There are usually four or five
spurs left near the head of the vine trunk and the vines
are free standing.
The replacement cane system is used in Bordeaux and
Burgundy and includes the Guyot. In this system canes
are trained along lateral wires with new canes being put
to use every year. This system has simple and double
variants, Guyot single and Guyot double. In the Cordon
spur system the trunk of the vines is grown horizontally
with many spurs left along its length. This system is
most commonly used in vineyards which have been fully
mechanized.
