Practices in the field:
Cover phytosanitary treatments are performed, using systemics only when really needed and following the integrated technical defense lines chosen by the Regione Veneto.
No treatments based on nitrogen are performed.
Subsoiling of the ground is performed to facilitate water draining to the thin strata of caranto (local clay).
Manual agronomic work: brown pruning, pollarding, shoot pruning, trellis systems (only the tree clipping is mechanical) and thinning of the veraison.
Manual grape harvest.
The grapes are collected in 170 kilo bins, adding dry ice (about 2kilos for each quintal of grapes) and the mass is cooled on refrigerator trucks.
