The white grape variety comes from Greece; the name means "August Jewel". Synonyms are Augoustelidi, Augoustelli, Avgoustolidi, Bostilidas, Goustoulidi, Goystolidi, Rompola, Vostilida, Vostilidi and Voustolidi. According to DNA analyses carried out in 2000 and 2007, there is a parent-offspring relationship with the variety Theiako Mavro, as well as a close genetic relationship with the often confused variety Robola (Rompola). Goustolidi is not a colour mutation of the red variety Avgoustiatis (with the same synonyms). According to DNA analyses performed in 2013, Goustolidi is one of the many direct descendants of Gouais Blanc; the second parent is unknown.
The medium to late-maturing vine is resistant to drought and botrytis, but susceptible to both types of mildew. It produces rustic, alcohol-rich white wines with moderate acidity, which are used, for example, with other autochthonous varieties in the traditional white wine Verdea. The variety is cultivated on the two Ionian islands of Kefallonia and Zakynthos, as well as in the Peloponnese. The area under cultivation in 2010 was 68 hectares (ten years ago it was 112 hectares).
