The Valtellina Superiore DOCG is a denomination from the winemaking area of the province of Sondrio. It is an elegant and structured red wine produced from the Nebbiolo vine, known locally as Chiavennasca. On the label, it can include the indication of origin from one of the five sub-zones: Maroggia, Sassella, Grumello, Inferno and Valgella. Each has different characteristics and expressions. Inferno, for example, which is the smallest cultivated area, is named after the heat emanating from the stones that are warmed by the hot summer sun. The reputation of the area is one of the oldest in Italy and, from a viticultural point of view, it was known since ancient Roman times, although it became even more important when, a few centuries later, the vineyards became the property of the Monastery of Sant'Ambrogio in Milan. In the enchanting nature of the valley, between the Alps and the river Adda, viticulture is carried out on steep terraces where the Nebbiolo grape produces this Italian wine excellence.
