Pruning

Pruning is the removal of selected parts of a grapevine to control its shape, growth, bud number and potential crop. The main annual pruning operation is usually carried out during the dormant winter period, when growers select the canes or spurs that will produce shoots and fruit in the next growing season. Pruning is a major tool for managing vine balance and vineyard productivity.

Winter pruning methods

• Cane pruning: retains one or more long canes with several buds, as in single or double Guyot systems.
• Spur pruning: retains short spurs with a small number of buds on permanent arms, as in cordon systems.
• Replacement pruning: selects renewal wood to maintain the vine’s structure and provide fruiting wood for the following year.

Why pruning matters

The number and position of retained buds influence shoot growth, crop potential and canopy density. Excessive pruning can reduce yield and encourage vigorous shoot growth, while insufficient pruning may create an overly dense canopy and uneven ripening. The correct approach depends on variety, vine age, vigour, spacing, climate and regional rules.

Pruning and vine training

Pruning is the annual selection and removal of growth. Training establishes the permanent structure and shape of the vine, such as cordon, Guyot or gobelet. Pruning is performed within the chosen training system.

Example: a Burgundy grower may use single Guyot pruning, retaining one fruiting cane and a renewal spur for the next season.

Chef’s note: pruning is a vineyard management decision that influences crop load and canopy development. Lower bud numbers do not automatically produce higher-quality wine; vine balance and site conditions matter.
