Leaf removal is a vineyard canopy-management practice in which selected leaves are removed around the grape bunches to improve airflow, sunlight exposure and spray coverage. It is commonly performed in the fruiting zone and may be done by hand or machine. The timing and amount of leaf removal depend on climate, grape variety, disease pressure and the desired wine style.
Opening the canopy around bunches can help reduce humidity and improve air circulation, lowering the risk of certain fungal diseases. It can also improve spray coverage and influence berry exposure and ripening. In cool or humid regions, carefully managed leaf removal may help grapes ripen more evenly.
Excessive leaf removal, especially on the afternoon-sun side of the row in hot climates, can expose berries to sunburn and heat damage. Removing too many leaves can also reduce the vine’s photosynthetic capacity. Some growers remove leaves early, before flowering or soon after fruit set, while others wait until later in the season; each timing can have different effects on berry development.
Leaf removal removes selected leaves around the fruit zone. Canopy trimming shortens shoots to control growth and maintain the canopy structure. Both are canopy-management practices, but they serve different purposes.
Example: a grower in a cool region such as Champagne may remove selected leaves around bunches to improve airflow, while a grower in a hot region may retain more shade to protect the fruit.
Chef’s note: leaf removal is a vineyard tool, not a guarantee of higher quality. The balance between airflow, sunlight and berry protection is essential.
