Castello di Stefanago is a historic winery in the Oltrepò Pavese that has always been committed to producing local wines, adopting increasingly innovative and less interventionist winemaking techniques over time. We are in Borgo Priolo, in the province of Pavia, where the Baruffaldi family has been producing wine for five generations, but only a few years ago decided to really invest in the quality of the final product. Today, the brothers Antonio and Giacomo have taken over the agronomic and oenological management of the family business, leaving the commercial and administrative management to their sister Antonietta. Castello di Stefanago now owns 20 hectares of vineyards, located on clayey and sandy soils rich in chalk in the subsoil at about 400 meters above sea level, characterized by perfect exposure to the sun, daily breezes and exceptional temperature variations between day and night that allow perfect ripening of the grapes. A pleasant place for the cultivation of varieties that are very common in the area such as Pinot Noir, Croatina, Riesling Renano, Muller Thurgau and Chardonnay. The care of the vineyard, converted to organic farming since 1998, is the starting point of the work of the new generation involved in the company; inter-row sowing, green manure practice, green pruning are all actions carried out in order to reduce systemic treatments to a minimum. An equally gentle and sensitive approach is also adopted in the cellar, where fermentations are all spontaneous, activated with the sole use of indigenous yeasts in steel containers without temperature control and the quantities of sulphites present in the bottle are reduced to the bone.
