The red varieties were planted (in espalderas) between 1974 and 1980 "a pie franco" (without grafting), thereby preserving the pure characteristics of each variety.
The vineyards with a density of 5000 plants/ha are trained to develop deep roots, preventing the need for irrigation.
The age of the plants and the absence of irrigation results in a well balanced vineyard, so that during the fruit ripening period the plants are not growing. Therefore, the grapes benefit from all the photosynthesis of the leaves and no energetic expenditure is lost in the generation of new buds.
Two months before the vintage the production of the vineyard is moderated (a green harvest) and the finest bunches are preserved, so that in the last 8 weeks the totality of the foliage concentrates in benefiting the remaining bunches.
