White grape, yet nebulous origins, the Perusini (1935) believed to have been imported from Hungary in Veneto and Friuli, but has no similarity with the grapes of that region. The Dalmasso (1937) cited documents attesting to the cultivation of a variety called "Tocai" in the Veneto region, dating back to 1771. The latest research identified it with the Sauvignonasse , a vine that has now disappeared in France, but present in significant quantities in Chile synonyms are used Tocai Bianco, Tocai Italian, Trebbianello, Cinquien, Sauvignon Vert, Sauvignon, Malaga, Doux Blanc, Sauvignon coarse grains, Sauvignon de la Corrèze. It is still wrongly confused with Tokay, which is the name of a Hungarian wine.
