Portia Winery, Burgos

Wine making facility with a production capacity of 1m bottles a year.

The Faustino winery group aims to explore new land and new wines through the opening of the Portia winery in the province of Burgos, Spain. The design integrates into the surrounding landscape, facilitating the wine manufacturing process and reducing the energy demands and visual impact of the building.

Arup's services on the project included structural, services, sustainability and facade consultancy. Arup also gave technical assistance during the site works.

The building takes the shape of a clover, expressing the three main production stages – fermentation in steel casks, ageing in wood barrels and ageing in the bottle.

Embedded in the surroundings

The two wings that contain the barrels and the bottle racks are partially embedded in the earth, creating favourable environmental conditions for wine ageing. The fermentation wing is exposed to allow the release of carbon dioxide.

The winery is designed to take advantage of the slope of the land. The grapes are unloaded by trucks on the upper deck, and gravity is used to move the grapes inside the building, maximising efficiency and minimising damage to the pulp.

Photovoltaic cells have been incorporated into the roof, and the recycled concrete structure uses thermal inertia to help control the indoor temperature, reducing energy demand.

The exterior walls are lined with large panels of Cor-Ten oxidised steel which give the building its distinctive colour. The third wing incorporates large volumes of stainless steel in the form of fermentation casks, referring to the building's function.
