Erbaluce di Caluso

This is a bottle of Erbaluce di Caluso, a DOCG Piedmont white wine made from the local Erbaluce grape. An ancient variety first mentioned in writing in 1606, it is thought to originate from the alpine foothills of northern Piedmont. The grape is named after the coppery pink tint of the fruit nearing harvest, which was likened to the light at dawn (erba/alba=dawn, luce=light). Naturally high in acidity, erbaluce can be made into dry and sweet wines, with the top designations being  Erbaluce di Caluso and Caluso Passito respectively. I tasted this wine at this year's wine fair.

PS. one of the synonyms of the grape is Uva Rustia, which is seen as La Rustia on the label.
