The white grape variety comes from Italy. Synonyms are Albaluce, Bian Roustì, Bianchera, Erbalucente, Erbalucente Bianca, Erbalus, Greco, Greco Bianco di Novara, Greco Novarese and Uva Rustìa. The name derives from the Latin "Alba lux" (light of dawn), which refers to the small, hard-shelled and whitish shining berries that tend to raisin. This makes them ideal for sweet wines in the style of a passito made from dried grapes. That the variety originates from Greece is an unproven hypothesis. It was first mentioned under the name Elbalus in 1606, and its exact origin is probably the current Canavese DOC area in the province of Torino in Piedmont.
According to DNA analyses, there is no relationship to the Greco variety. However, there is a close relationship with the variety Cascarolo Bianco and possibly Clairette. The early to medium ripening vine is susceptible to powdery mildew. It produces rather light-alcohol white wines with moderate acidity. The variety is cultivated in Piedmont, where it is reborn through clone selection. It is used in the DOC white wines Canavese, Colline Novaresi, Coste della Sesia and Erbaluce di Caluso. In 2010, 319 hectares of vineyards were registered.
