The commune of Caluso, is known for a very particular grape variety known as Erbaluce. Despite the relatively small size of the modern-day appellation, the Erbaluce wines of Caluso have had a rather long and noble history. Since the early 1600s, the sweet Erbaluce wines have had an important place on the Piedmontese table, as well as in the court of Napolean and other important European dignitaries. The region was awarded Piedmont’s first white DOCG appellation – Erbaluce di Caluso – in 1967. Erbaluce, who’s name comes from the words “erba” meaning dawn and “luce” meaning light, referring to the pinkish-copper hue of its skin when the variety is ripe, is high in acidity that can produce sparkling to dry, still wines to sweet “passito” wines. About 250 hectares of Erbaluce are planted in the provinces immediately surrounding Turin, with the best sites in the amphitheater near Caluso that have sandy-gravel soils that supply this difficult-to-grow variety the right amount of nutrients.

Grapes are sourced from the younger vines in the vineyard which is located between 310 and 350m above sea level facing south-southeast. Vines are trained in a traditional Canavese-style pergola. Grapes are harvested by hand in early September.
