What are the three main considerations a producer may need to make when choosing a site?
Which environmental conditions does a producer have to consider?
What business considerations must be made by a producer when selecting a vineyard site?
Proximity to utility infrastructure (power, water etc.)
Availability of a vineyard workforce
Accessibility for machinery
Cost of land
What must a producer consider regarding grape variety when selecting a site?
It must suit climatic conditions
How is a new vineyard prepared?
Existing vegetation is cleared
Fertility tested (and corrected with fertiliser if necessary)
Young vines are planted by hand or machine
Vines protected from animals with plastic sleeves
Irrigation allowed to help young vines establish themselves
Why is irrigation allowed in some places after new vines have been planted?
To allow the vines to establish themselves
When does a vine's first yield usually come?
In the third year after planting
At what age on average are vines usually replaced?
30 - 50 years
What is the main factor that makes old vines desirable?
They give a greater concentration of flavours
What are the potential disadvantages to growing an old vine?
Susceptibility to disease
For how long is a vineyard typically left fallow after the vines are dug up?

What is vine training?
The shape of the permanent wood of the vine
What are the two principal branches of vine training?
Both head training and cordon training can be...to benefit from heat retained by the soil or...to avoid frosts
Describe a head-trained vine
They have very little permanent wood
Some have only a trunk
Some have a few arms protruding from the trunk
They can be spur-pruned or replacement cane pruned
Describe a vine which is cordon trained
A trunk with one or two arms of permanent wood
Usually spur pruned
Describe a positive and negative of cordon training a vine
The sturdy permanent cordon with shoots positioned along its length, makes mechanisation easier
It can take longer to establish because of the greater amount of permanent wood
Cordon training can also be used to create...
Big vine structures
What is pruning?
The removal of unwanted leaves, canes and permanent wood
What is the purpose of pruning?
It shapes the vine and limits its size
When does pruning typically take place?
Every summer and every winter
What is the main purpose of winter pruning?
To determine the number and location of buds that will form shoots in the coming season
Why is it important to ensure that buds are not too close together?
To help with canopy management
What are the two styles of winter pruning?
Replacement cane pruning
Describe spur pruning
Spurs are either distributed along a cordon or around the top of the trunk
