Rossignola

[1] The Italian botanist Ciro Pollini (1782–1833) noted that Rossignola was growing in Verona at least as early as 1818.

The synonyms Rossetta del Lago and Rossignola di Montagna has led to some speculation that the grape was related to the nearly extinct and no longer commercially cultivated Lake Garda variety Rosetta di Montagna but according to Master of Wine Jancis Robinson and Swiss geneticist Dr. José Vouillamoz the two varieties are distinct.

A similarity in synonyms also leads to Rossignola often being confused with the Lombardy wine grape Rossola nera that is an offspring of Nebbiolo.

[1] Rossignola nera is a late ripening variety that can be very vigorous and high yielding if not kept in check by winter pruning and green harvesting.

[1] In 2000 there were 341 hectares (843 acres) of Rossignola planted in Italy, most of it in the Lake Garda and Valpolicella area in the Veneto.

Rossignola has been grown in the Verona province, including around Lake Garda (pictured) , but it is a distinct variety from the ancient Lake Garda grape Rosetta di Montagna.
The Valpolicella region where Rossignola is a permitted blending variety in the DOC wines of the area.
