London architects Foster + Partners have finished their newest creation, the Faustino Winery in the Ribera del Duero region of Spain. The building is the firm's first winery. It is made up of three arms that each house a different stage of wine production. The structure is made out of Corten steel shingles. The interior of the winery is designed so that people on the mezzanine level can view the processes from above. The 12,500 square-metre facility is designed to produce about one million bottles per year. The project began in 2007, and was finished recently this year.
