Soil
The soil is made up of acidic materials, low in fertility and highly evolved. The vineyard is situated on an area of Raña. This is a system of alluvial deposits formed from the front of the mountain ranges and made up of very meteorized slate and quartzite blocks on a sandy matrix.

Varieties
Vallegarcía has 31 ha of vines, planted in 1999.
• The vineyard contains six grape varieties, five red and one white.
– Reds:
Cabernet Sauvignon (clone 337), 8 ha
Syrah (clone 174) 7 ha
Merlot (clone 181) 6 ha
Petit Verdot (clone 400) 2 ha
Cabernet Franc (clone 214) 3 ha
– Whites:
Viognier (clone 642) 5 ha

Rootstock
• The entire vineyard is grafted on the same rootstock, 3309 Couderc.
• The 3309C is a hybrid of Riparia x Rupestris genetically closer to Rupestris than Riparia for its ampelography and its characteristics, moderate vigour and precocity.
• It adapts to deep soils, it has a low resistance to active limestone and little tolerance to drought and excess water.
• It is a recommended rootstock from a quality point of view.

Planting density
• The plots planted in 1999 have a planting density of 2008 plants per ha, in a frame of 3 m x 1.66 m.
• The areas planted in 2005 and 2008 have a planting density of 2777 plants per ha, in a frame of 3 m x 1.20 m. Trellis systems and pruning
• Smart Dyson Trellis. It is a vertical shoot system split in two, with part of the vegetation going upwards and the other part downwards.
• Pruning is on spurs located on a unilateral cordon situated at 1.10 m and with the spurs pointing both upwards and downwards.

Monitoring of the crop
• The crop is monitored by several radio transmitters, located at different points of the vineyard, which transmit data collected by sensors that continuously measure different variables
• The combination between the accuracy of the measurements taken by the sensors and the real time radio transmission of data, makes this technology a powerful tool for the improvement of irrigation strategies.

Sensors and data integration
• Weather data (air temperature, rainfall, wind speed and direction, leaf moisture, solar radiation, atmospheric pressure, soil temperature…)
• Sensors of soil humidity at different depths
• Water consumption monitoring
• Dendrometers
• ETo calculation
