Flaking takes place in April / May and consists in the elimination of the basal leaves adjacent to the bunches. This process is also repeated shortly before the harvest. The early intervention is done to clean the bunches of floral residues from which diseases and infestations can develop. The peeling also serves to obtain less compact and smaller clusters, less vulnerable to diseases.

By thinning grapes, on the other hand, we mean the timely intervention that involves the elimination of part of the load per plant (bunches) that are cut and left on the ground. It is a fundamental intervention that allows the plant to concentrate its resources on fewer clusters in order to improve ripening. The thinning operation must not be carried out randomly but taking into account the visual appearance of the bunches and their position on the plant.
