Goustolidi is an old Greek wine grape variety of the Ionian islands, mentioned in a folk poem of the 16th century (Katramis 1880). It used to be the most important and most widely cultivated variety of Zante, but today, its cultivation has been significantly reduced. It is recommended for cultivation in Prefectures of Kefalonia, Zante and Achaia. It was cited by Viala and Vermorel (1909) as “Goustolidi” and by Guillon (1895) as “Coustidini”. Molon (1906) and Pulliat (1888) consider Goustolidi a closely related variety to the Italian variety Giustulisa bianca, while Guillon considers Goustolidi equal to the French varieties. It is mentioned as Avgoustolidi, Vostolidi, Vostylidi, Goustoulidi.
