The Spanish winery in Quintanilla de Onésimo in the province of Valladolid in Castile-León is named after the pet name of the owner. Born in Denmark, Peter Sisseck was inspired as a 14-year-old by his uncle Peter Vinding, who ran Château Landiras in Bordeaux. His winemaking career began at Château Rahoul in Graves. In the early 1980s, he travelled to Sonoma, where he worked with Zelma Long of Simi Winery. Later, he studied agricultural engineering in Copenhagen. In 1990, he came to the Spanish region of Ribera del Duero and took over the management of the Monasterio winery, where he still works in an advisory capacity. Influenced by the garage wine trend of the 1990s, he then started the "Pingus" project.
