The production area and the vineyard
Alta Langa originates in the hills of the provinces of Asti, Alessandria and Cuneo on the right bank of the River Tanaro.
The cultivation of Pinot Noir and Chardonnay grapes requires moderately-fertile calcareous clay marl soils.
The vineyards have to be located in the hills, at a minimum altitude of 250 metres above sea level, so the use of grapes grown in damp, flat, 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 admissible pruning techniques 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. The must yielded from each pressing phase must be less than 65%.
