While other great Spanish wines are seeing their international success fade, Pingus (first vintage dating back to 1995) is still far from having finished its progression on the market. The Bodega is nestled in the heart of the Ribera del Duero, the largest of the five controlled areas in the wine producing region of Castile and León, and was officially granted the title of "Denominacion de Origen" in 1982. Owner and agricultural engineer Peter Sissek carries out vinification himself, following the advice of his friend and owner of the Château de Valadraud in Saint-Emilion, Jean-Luc Thunevin.

PSI (named after the letter in the Greek alphabet and depicted in the shape of a vine stock on the label) is produced by a cooperative of quality-focused wine growers who, in the main, cultivate their vineyards according to biodynamic principles. It was the inspiration of Peter Sisseck who is committed to developing the potential of the Ribera del Duero’s older vineyards by working with their owners. The wine has a nose of red fruits (forest fruit) and the palate unveils refined tannins and even more red fruit.
