Erbaluce is one of the oldest and most typical white grape varieties in the Piedmont region, and in recent years it has been greatly rediscovered and developed. The first evidence of its existence dates back to the 17th century and its area of origin was originally identified as the foothills of the Alps in the province of Turin, in particular the Canavese area, where it is still widespread today. Its production is closely linked to the hilly territory of Caluso, protected by a DOCG (Denomination of Controlled Origin) established in 2010, which also includes some territories in the provinces of Biella and Vercelli. This grape produces important passito wines and various sparkling wines, as well as fresh and mineral white wines, sometimes aged in wood, characterised by energy and vitality, as well as a discreet ageing potential. These are territorial expressions of northern Piedmont that have an ancient origin, which some producers have rediscovered with significant success.
