Tying provides the basis for a controlled training system of the vine.
The horizontal alignment of the shoots ensures that all eyes expel simultaneously.
This activity is best carried out in damp and cool weather.
In very dry conditions the shoot is brittle and breaks easier.
Weight distribution is achieved by fixing the shoots on two wires rather than on one.
In former times this activity was done by tying strings by hand.
Today the shoots are fixed mechanically using thin wires.
This work is done after the pruning and before the bud break in spring.
