This traditional training tunnel system is a high-picking system used for wine grapes and especially table grapes. This form has been used since ancient times. The picture below on the left comes from the manual of the Corutti family in Verona around 1375. Between supporting poles made of wood, metal or concrete, horizontal devices (exactly horizontal or also slightly inclined for optimal sunlight) are placed at a height of two to four meters. These can be lattice-like wooden frames, horizontal poles or wire frames. Depending on whether the shoots are pulled to one side or two sides, we also speak of one-armed or two-armed systems. The shoots form a more or less closed foliage canopy, Italian pergola. High yields can be achieved with this system. All maintenance work must be done from below, mechanized work is difficult.
