The production area and the vineyard
Alta Langa originates in 149 villages on the hills of the provinces of Asti, Alessandria and Cuneo on the right bank of the River Tanaro in the southern Piedmont region.
The cultivation of Pinot Noir and Chardonnay grapes requires moderately-fertile calcareous clay marl soils.
The vineyards must be located in the hills, at a minimum altitude of 250 metres above sea level, so the use of grapes grown in damp, valley-floor vineyards is strictly forbidden.
Production regulations state that every vineyard must contain at least 4,000 vines per hectare. The vines are trained using the low espalier system, and the pruning techniques admitted are traditional Guyot and spurred cordon, at a maximum height from the ground of 90 cm. The maximum grape yield per hectare is 11,000 kg, while the yield from each pressing phase must be less than 65%.
