That Cornalin d'Aoste and Humagne Rouge are in fact the same variety was established by DNA profiling at Changins in Switzerland and Aosta in Italy. At the same time, it was established that it is not related to the white variety Humagne Blanche. Researchers at UC Davis later established that Cornalin d'Aoste is an offspring of Rouge du Pays, also known as Cornalin du Valais.^[1][2][4]
