The Bodegas Protos technical department conducts comprehensive controls of the vineyard, in an ongoing pursuit for the utmost quality each year in preparing our wines. This is no easy task, given that it entails controlling 1,400 hectares spread throughout the Ribera del Duero region.

We strive for excellent quality and for this reason, we have located our vineyards in the best estates and in areas that are best suited to growing Tempranillo grapes (100%). This vast number of hectares is spread out over numerous plots with an average size of around 1 hectare, highly dispersed throughout the Ribera del Duero region (spanning the best areas in the provinces of Valladolid, Burgos and even Segovia).

Most of our vineyards are planted on south-facing hillsides, in search for the hours of sunlight needed for optimal ripening.

There are highly diverse soil types along the Duero River, but in general, the area features loose, not very fertile soils that have limited organic matter, and in which limestone is sometimes a predominant element. In most cases they have a loamy or sandy loam texture.

Our vineyards range in elevation from those located on plateaus, at elevations of up to 900 metres, to those located in valleys, where the topography ranges from 750 to 800 metres.

The climate
The climate in this region has a great influence on the vineyards, which can be seen clearly in the life cycle of the vines and plays an important role in plant development and grape ripening, thus bestowing the Tempranillo variety with its special quality.

  • Low rainfall rates – 450 mm per year.
  • Hot, dry summers with temperatures in excess of 35 ºC.
  • Long, cold winters with frost at night, reaching temperatures of 18 ºC below zero.
  • Long temperature variations between day and night during ripening, fostering slow and gradual ripening of the grapes, which leads to an accumulation of sugars, higher tannin and polyphenol concentrations and more intense colour in the wine.

Indeed, this is a Mediterranean climate with a Continental influence and more than 2400 hours of sun per year.

The grapes we use to make our wines are grown:

  • Trellis vineyards – 60%
  • Goblet-trained vines – 40%

Continuous monitoring of the vineyards.


  • Control and monitoring of pruning.
  • Control over fertilising.


Control over springtime tasks such as:

  • Green pruning.
  • Lateral bud rubbing.
  • Leaf removal.
  • Tipping.
  • Cluster thinning.

Pest control: Monitoring for potential pests and diseases that affect the vineyard up to harvest time.

Thinning is done at veraison and up to three times in order to remain within the limit of 5000kg/ha (a self-imposed limit by Protos, as the Regulating Council for the Ribera del Duero Designation of Origin has established a maximum of 7,000 kilograms per hectare). True to our quality policy, Bodegas Protos has established certain average yields for our vineyards:

  • In young vineyards: 4,000kg/ha
  • In old vineyards: 2,500kg/ha

Therefore, we make:

  • 1,000,000kg of grapes from old vineyards.
  • 4,000,000kg of grapes from young vineyards.

Harvest planning.

  • Depending on the area.
  • Age of the vines.
  • Analytical indexes (TPC, colour, pH, alcohol by volume, acidity)

For this task, we must be aware of the location of the vineyards, assigning them inspection control sheets. A database is created with all the plots we control and their characteristics. To this end, we have specific vineyard software and maps to be able to locate all the plots and ensure traceability from the vine to the bottled wine.

We perform a careful selection in the vineyard, based on age, estate, analysis, and so on, during the ripening process. All the plots are analysed. The analytical parameters give us an idea of the quality of the vineyards, assigning a quality level to each batch of grapes.
 These analyses enable us to assign the different fermentation tanks, achieving uniform quality.

During the harvest.

Strict control over the vineyards, keeping in mind the origin of the grapes in order to discern the best date for harvesting, so that they are gathered when they are perfectly ripe. All the harvesting at Bodegas Protos is performed manually, using 20 kg crates for old vine grapes.
Once the grapes are received at the winery, they are sorted on the Sorting Tables. This sorting is done first cluster by cluster and then grape by grape, thus ensuring the utmost quality in this process.

Our production capacity comes to a total of 5,600,000 kg.
