Erbaluce is a white Italian wine grape grown primarily in the Piedmont region around Caluso. In addition to dry table wines, it is used to make sweet wines passito with deep golden coloring. The grape has a long history in the Piedmont region, with the first written record dating to 1606, and most likely originated in the alpine hills of northern Piedmont. This ancient vine, whose presence in the region is traced back to the 17th century, got its name from the brightness and luminosity of its grapes (Erba Luce translates to Grass Light).
Erbaluce di Caluso is a DOC wine. It's cultivated in Canavese, in the Serra d'Ivrea and on the hills surrounding Lake Viverone, in the province of Turin, as well as in some municipalities in the province of Biella. For a long time it has been cultivated in the province of Novara, where it's called Greco (Greek).
Viticulture and winemaking
Wines made from Erbaluce tend to be dry with noticeable acidity. While the grapes acidity makes it ideally suitable for sweet wine production, the dry wines need to have considerable amount of fruit in order to balance that acidity. Both the dry and sweet styles of Erbaluce tend to exhibit characteristic apple aromas and flavors. Since the 1990s, Piedmontese producers have been working on improving the quality of Erbaluce wines to compete with the whites of Cortese and Arneis.
It has medium leaf, five-lobed, light green, medium-long cluster conical long, sometimes winged, compactness media berry spherical, medium, with skin of color amber, rich in bloom.
Erbaluce is also known under a variety of synonyms. These include Albaluce, Albalucent, Bianco Rusti, Erbalus, Erbalucente, Uva Rustia.
