Leaf-pulling is an important vineyard-management operation, in which certain leaves are removed manually from the vine in order to allow more sunlight to penetrate into the canopy and to better ventilate the clusters. It is also an indirect defence against the main fungal diseases, since most fungi develop and spread in humid conditions.
Leaf-pulling must be performed early in the season, since the grape cluster has to gradually adapt to light and heat; if carried out too late, the clusters could be subject to burning, caused by the acidic components in the berries.
