Much attention has been paid in recent years to the various management factors that influence wine quality: Soil cultivation, water and nutrient supply to the vine, foliage management, yield control. The question of how to prune vines properly, on the other hand, has hardly been addressed. Yet pruning not only determines the quantity and quality of the grapes. It also facilitates all subsequent work in the vineyard. At least as important is the fundamental influence of pruning on the health of the vine, on its resistance and longevity: poor pruning shortens the age of the vines, while well-considered pruning can prolong it.
