Via Foster + Partners
Bodegas Portia is a new winery for the Faustino Group in the Ribera del Duero, one of Spain’s foremost wine-producing regions. The project is Foster + Partners first winery and was an opportunity to look afresh at the building type, using the natural topography of the site to aid the winemaking process and create the optimum working conditions, while reducing the building’s energy demands and its visual impact on the landscape.
The 12,500 square-metre facility has a production capacity of one million bottles per year. The building’s trefoil design expresses the three main stages of production: fermentation in steel vats; ageing in oak barrels; and finally, ageing in bottles. These are controlled by an operations hub at the core. The wings containing the barrels and bottle cellar are partly embedded into the ground to produce the most favourable environmental conditions for ageing the wine, while the fermentation wing is exposed, allowing carbon dioxide to be released. A road rises to the roof of the building, where the harvested grapes are delivered straight into the hopper: the winery is designed to take advantage of the sloping terrain, using gravity to aid movement of the grapes within the building, maximising efficiency and minimising damage to the grapes. The concrete structure is clad in shingles of Corten steel.
The site in the Ribera del Duero, approximately 150 kilometres north of Madrid, has extremely cold winters, as well as hot summers with limited rainfall. The deep overhang of the roof canopy provides shade and the building is designed to regulate the internal temperatures, at the same time as reducing energy demand. By partly embedding the building within the landscape, its visual impact is minimised and the passive environmental benefits are maximised – the roof incorporates photovoltaic cells and the thermal mass of the concrete structure helps to control interior temperatures.
At the heart of the winery a raised public gallery extends into glazed mezzanine areas, which project deep into each wing, allowing visitors to enjoy elevated views of the different processes. Between the wings is a light-filled public reception and administration area, where extensive terraces and pools of water overlook the vineyards. Lined with deep-stained old wine barrel slats, the public areas are designed to evoke the rich tradition of winemaking in the region.
Lord Foster said:
“Bodegas Portia is our first winery, so we had no preconceptions about how it should work. It was an opportunity to start from first principles – to examine the different stages of wine production and to try to create the ideal conditions for them to unfold. The wine was the starting point, as well as the beautiful setting in Ribera del Duero. Using materials that draw on the region’s winemaking traditions, with public spaces open to the landscape, will enhance the visitor experience.”
Bodegas Portia: Gumiel de Izan, Ribera del Duero, Spain: 2004 –2010
Client: Bodegas Faustino SL
Appointment: September 2004
Construction: August 2006 – September 2010
Location: 150km north of Madrid on the main traffic route connecting the major cities in Spain, in the Ribera del Duero region, one of Spain’s foremost wine producing area.
Building Type: Winery – for the production of one million bottles of red wine per year.
Concept: Trefoil plan that reflects the principal process stages: fermentation in steel vats; ageing in oak barrels; and storage and refinement in the bottle. The two volumes housing the ageing processes are buried into the natural slope of the site, in order to enable gravity-based delivering of the grape harvest. Taking advantage of the thermal cooling benefits of the earth, the building is partly embedded in the landscape. Operational support and visitors facilities are strategically located in the centre of the building, with the public areas on a mezzanine level. There is also a restaurant with views of the landscape.
Gross Area: 12,500 sqm
Net Area: 11,300 sqm
Site Area: 400 acres
Building Height: 14.5 m (partially embedded into the sloping landscape)
Number of storeys: Two operational levels + grape reception roofdeck (external)
Structure: Concrete structure with pre-cast elements where the structure is exposed and in situ cast concrete where the structure is buried underground, i.e. retaining walls. The boundary link between above and below-grade servicing structures is given visual expression through a continuous linear skylight.
Materials: Materials of building echo the materials used in wine production – steel, oak and glass.
Cladding: Corten Steel shingle cladding to all principal vertical elevations.
Sustainability: The partly buried structure, as well as the concrete framing of the building, maximises its thermal mass to maintain a constant internal environment and the optimal thermal conditions required for the ageing of wine. The wing where the tanks are housed is naturally ventilated to allow CO2 to escape during the fermentation process.
Widescale integration of photovoltaics is anticipated into the design of the roof, spreading over the three wings to maximise the surface for capturing energy.
Production Capacity: One million bottles of red wine per year.
Storage Capacity: 6,000 barrels of 225 litres, and 750,000 bottles.
