It may seem that talking about irrigation for a crop that is used to being placed in not wet area, and, though, able to support dry season, is a nonsense. In fact Vitis vinifera used to be a small plant with good root system, able to assure sufficient water. The new way of managing vineyard, on the contrary, needs bigger plants, tall and wide, more accurate quality and high production. That's why, in some situation, rain may not be sufficient. Irrigation is the solution for this and, if it is managed in a proper way, can improve quality of the grapes and, consequently, of the wine.
