The white grape variety originates from Italy. Synonyms are Aglionza, Alconza, Aleonza, Alionga Bianca del Bolognese, Allionza, Allionza Bianca, Glionza, Leonza, Uva Lonza and Uva Schiava. Because of the latter synonym, it must not be confused with the Greek variety Sklava. There is also no genetic relationship to the Schiava varieties. It was already mentioned in the 14th century by Petrus de Crescentiis (1230-1321). The assumption made by French ampelographers that it was present in the south of France in the 19th century is unlikely. According to DNA analyses carried out in 2001, there is a close genetic relationship to the Trebbiano Toscano variety. The late-maturing vine is resistant to frost, botrytis and powdery mildew. It is used as a wine grape and table grape. The variety is grown in Emilia-Romagna (provinces of Bologna and Modena). In 2016, 9 hectares of vineyards were designated (Kym Anderson).
The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
