"The wine gives brilliance to the countryside, exalts hearts, lights the pupils and shows the dance to your feet."
José Ortega y Gasset


The reality of this project is forged between the stone walls of the Convent of las Claras, in Peñafiel.

The Doctor Agronomist José Carlos Álvarez and his project decide to materialize the history and geology of the Ribera del Duero in wine. The experience accumulated in the Ribera del Duero over many years, is combined to convey the expressiveness of the Tempranillo grape. Fine Tinto.

History, tradition, innovation and wisdom.


Raw material

Bodegas Convento de las Claras selects, for the elaboration of its wines, the soils and vineyards of exceptional quality of the Ribera del Duero.

The only grape variety used for our wines is Tempranillo. We firmly believe in its winemaking potential as a unique and representative variety of the Ribera del Duero.

The selection of vineyards is carried out in accordance with soil studies that, after decades of years, have produced wines of the highest quality, with the sole purpose of expressing the terroir of each of them, brought to the maximum exponent after processing.

This selection of vineyards between 30 and 90 years old, with very low yields, located at altitudes above 850 meters, with a sustainable viticulture and respectful with the environment, results in wines of the highest quality.

The soils


The soils


The páramos are extensive, flat surfaces, constituted by horizontal limestone strata, subjected to processes of karstification. These occupy the north-eastern margin of the basin, with enclaves west of Valladolid and south of the Duero.

On the limestones of the páramo, red soils have been developed which, due to the mixture of horizons and decalcification, have become patterned. The largest extensions correspond to evolved soils, with alkaline pH and high proportion of carbonates. They correspond to calcium and chromic luvisols in which the processes of decarbonation, flushing and illuviation can be observed.

If the evolution is smaller, calcareous cambisols and, to a lesser extent, chromic and ecutric cambisols are found. If they have hardly evolved or there has been a regression there are relic leptosols.

Ribera del Duero


Constitute the slope of the páramos and represent the transit between limestone wastelands and detrital countryside. The slope facies represent the maximum extension of marginal lacustrine facies, characterized by marls, gypsum and clays in the lower levels and calcareous marls and marly limestones in the upper ones. In these facies the soils are represented by calcic and gypsic regosols. On marls and limestones more evolved soils can be found: like the calcareous and ecutric cambisols.


During the Quaternary, the main river courses have left a large number of terraces.

In the lower terraces are undeveloped profiles, often Cambois.

In the upper terraces appear luvisols (calcic or chromic) and, less frequently, acrisols and planooles.

These profiles usually undergo processes of decarbonation, flushing and illuviation.

In the vegas of the Duero and its tributaries are fluvisols.

Fluvisols are the most fertile soils in the basin.

The fluvisols that reach greater extension are the eútricos, located in the tertiary depression of the Duero. Calcareous fluvisols are found in the limestone paramos, and in those that run through acidic siliceous rocks, dorsal fluvisols.



Calcium rains

The term Luvisol derives from the Latin word "luere" which means to wash, referring to the washing of clay from the upper horizons to accumulate in a deeper area. The Luvisols are mainly developed on a wide variety of unconsolidated materials such as glacial, wind, alluvial and colluvial deposits.

They predominate in flat areas or with mild slopes of temperate, cold or warm climates, but with a dry season and a wet one, like the Mediterranean climate.

The profile is of type ABtC. On the argic horizon can appear an albic, in this case they are intergrados towards the albeluvisoles. The wide range of original materials and environmental conditions, give a great diversity to this Group.

Calcium Luvisol: with a calcic horizon or concentrations of secondary carbonates between 50 cm and one meter deep. There are three modalities:

Hypercalcic. The calcium horizon has at least 50% calcium carbonate equivalent.

Hypocalcic. It only has concentrations of secondary carbonates in the first meter of soil.

Orticálcic. It has a calcic horizon in the first meter.



The alluvial soils are soils of fluvial origin, little evolved although deep. They appear in the vegas of the Duero and its tributaries.

Fluvisols are soils with a poorly developed profile, formed by materials transported by water currents.

They are formed by round gravels, sand, clays and brown and gray silts.

They are hot floors with good drainage.

In the plains of alluvial soil, the millennial drag of sediments, silts and clays dragged from the slopes by the runoff waters are conjugated.

They are mostly of a frank texture, with a silty tendency and sometimes very rich in clay in depth. They are found in the flood plains of the Duero.

Being formed by sedimentary materials transported, of fluvial origin, they are characterized by strong vertical variations, due to seasonal or periodic alterations of the fluvial regime, which in the same soil can originate fine or coarse sediments.

Due to this, they are characterized by a textural heterogeneity, which indicates the successive phases of the alluvium.


Calcium Haploxeraf

They are outcrops of carbonated formations.

They are clay-calcareous soils, with the advantage of sponging in winter to receive water and closing in summer in order to retain it.

These materials have by definition more than 20% carbonates and the rest of the rock is composed of silt and clay or quartz.

The soils coming from the alteration of these sedimentary rocks are formed from the residues left by the dissolution of carbonates. Thus, the type of soil formed is related to the predominant type of "impurities" in limestones and dolomites.

If the limestones are rich in clay, the result is clayey and impermeable soils, with pH and saturation of high bases.

If the limestone is rich in sand, the soils formed are thick, permeable, less basic.

If the limestone is rich in iron impurities, such as hematite, the result is a red soil, usually acidic.


Typical Xerorthent

Enthenols are orthents with a dry moisture regime.

The typical Xerorthents correspond to neutral or basic soils, developed in inconsistent materials, capable of providing bases (marls, marl-limestones, sands, gypsums, arches, quaternary deposits: colluvial, alluvial and terraces), usually rich in calcium carbonate.

They are frequent in the countryside and on hillsides and valley bottoms of the physiographic unit of the Páramos, in the central and eastern areas of the Ribera del Duero.

Frequently, they are associated cartographically with Inceptisols of the Haploxerepts or Calcixerepts groups.


The winery

Bodegas Convento de las Claras is located in Peñafiel, in the heart of the Ribera del Duero.

The building hides a cozy and functional winery, ideal for the production of quality wines and for your visit.

In addition, the winery, as an open space for wine tourism, allows the visitor to visit its facilities and know, from within, how we make wine and satisfy their curiosity at the hands of our team.



Our challenge is the production of high quality wines that express the nature and personality of each of our terroirs, which, the object of research and experience of many years, represent the greatness of the Ribera del Duero. The combination of unique soils (clay-loam, clay-sandy and franc-calcareous), old Tempranillo vines, as well as the climate of the Ribera de Duero and the meticulous work in the vineyard over the years, result in grapes of exceptional quality that are treated in the winery with the greatest possible care, in order to extract all its oenological potential. Therefore, each payment is vinified and matured in new barrels, separately, in order to express their unique identity.Visítanos
