The most diffused system on the hills of Piacenza is the Simple Guyot. This vine training system creates the so called ‘’trellising’’ that shapes our hills, turning them into an orderly sequence of longitudinal lines that catch the attention of those who visits our territory. This vine training method allows the elimination of the entire vegetation, except for a one-year old vine branch (fruiting cane) and a small spur, meaning portions of vine shoot of reduced sizes, holding two or three buds. This vine training system is traditionally the ideal one for our typical vines like Barbera, Croatina, Malvasia and Ortrugo. The Guyot is also the system that involves most manual work, with particular reference to pruning, which is the main process: it is carried out when the plant is in the vegetative stage and significantly affects the quality of the next crop.
Another vine training method locally implemented is Casarsa. This vine training system, in its traditional form, consists of a cord permanently placed at about 1.60-1.70 metres from the ground. 3-4 fruit canes are introduced along this cord, carrying 4-5 buds each. Above the supporting wire of the cord, a framework is placed, consisting of two wires. The fruiting canes are not tied so when the buds produce the grapes, the entire production area tends to bend downward with the bunches of grapes dropping as suspended in the air, protected from the sun. In our land, the Casara system does not foresee any framework above the cord, thus leaving the vine completely free. This system in the hills of Piacenza is not as popular but it is a traditional method, always present in all cultivated vineyards.
During the last few years, due to the increasing needs for automation, especially in pruning processes, the Spurred Cordon system was introduced, which foresees pruning after the winter break, leaving one or two cordons that will be left on the plant for at least four or five years. Four spurs will be left on these cordons, at equal distance from one another. Pruning in subsequent years will consist in renewing the spur every year. This wine training form also consists in ‘’trellising’’ and is suitable for Barbera and Ortrugo vines.
