The nature of the land, its position and exposure and the climate (with
reference particularly to the temperature, light and humidity) are perfect
for this type of cultivation and explain the widespread presence of
vines in the territory. The most practised forms of cultivation are:
Sapling
Il Guyot (a contained order of the vineyards which results
in a high density of vine stumps per hectare and a limited yield of
fruit per stump).
The average yield of the area, per hectare, is 60 quintals with a sugar
content which varies between a minimum of 17% to about 22% and even
above for the particular methods of cultivation suitable for the production
of dessert wines. The cultivation practises, treatments of the land
and the vines and above all control of vine diseases, the latter essentially
present to a limited extent, are supervised by the staff of the "Technical
Assistance Centres". The staff operate all over the territory and
only a brief warning to the vine-growers is necessary. An integrated
biological approach is usually adopted to combat adversities caused
by animal parasites, after having verified the indispensability of the
intervention on the vineyard.
The Grape Harvest
For the delivery of the grapes to the vinification plant, the vine-grower
members are obliged to respect a rigidly studied timetable. The harvest
is guided by definite indicators: the relative data on the vineyard
has to be recorded and consulted, the moment the fruit reaches the index
of physiological ripening has to be established, as does the resulting
best commercial value of the grapes, according to the type of wine to
be produced.
