The red grape variety comes from the aosta Valley in Italy on the Swiss border. The name is probably derived from "corniolo", the Italian name for the cornelian cherry. Synonyms are Broblanc, Cornallin, Corniola, Cargnola ( Italy ); Cornalin d'Aoste, Cornalino, Humagne Rouge ( Switzerland ). Despite apparently indicative synonyms or morphological It must not be similar to the varieties Olivette Noire (Corniola nera), Petit Rouge or Rouge du Pays (Cornalin du Valais) can be confused.
The variety was widespread in the Italian Aosta Valley in the 19th century. Towards the end she came to the Swiss canton Wallis, but was called Humagne Rouge there for almost a century (but is not of the variety Humagne Blanche related). The biologists Dr. Giulio Moriondo and Dr. Joseph. Vouillamoz put through in 1999 DNA analysis found that the Cornalin d'Aoste (Cornalin) and Humagne Rouge, which had previously been considered independent, were identical. It also turned out that Cornalin was a natural cross between Rouge du Pays and an unknown and probably already extinct variety has emerged. It was also clarified that the previously assumed equality with the variety Petit Rouge does not correspond to the facts. In Switzerland, Cornalin becomes a group of grape varieties Old plants counted.
The late-ripening vine is generally resistant to fungal diseases, It produces colorful red wines with rustic, smoky tannins and aromas of black fruits and pepper. The variety is cultivated in the Italian Aosta Valley on only one hectare and is permitted here in the regional DOC wine. In the Switzerland however, the total acreage in 2010 was 244 hectares (Kym Anderson ).
