Known locally also as Humagne Rouge, . In addition to being used in some Vallée d'Aoste DOC blends, this grape has been awarded its own sub-denomination. The wine is purply-red in color with garnet highlights, with intense, spicy perfume, low acidity and slightly tannic.
Cornalin d'Aoste or Humagne Rouge is a variety of red wine grape. It was named after the Aosta Valley in northwestern Italy where it is presumed to have originated, but where it is now almost extinct. It is primarily grown in the Valais region in Switzerland, where it is called Humagne Rouge, and the total Swiss plantations of the variety in 2009 stood at 128 hectares (320 acres). This vine arrived in the Aosta region toward the end of the 14th century
Viticulture and winemaking
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.
The grapes from the vineyards suited originate a fine wine, violet-red color, tending to garnet with maturation and aging, the fine and very intense, reminiscent of spices (pepper and vanilla) and some aromatic (thyme, tobacco ), if well aged, the taste turns soft, full, pleasantly tannic, with excellent balance and persistence. It may very well bear the noble aging in French oak barrels, but equally well tolerated than the single bottle.
The recognition of VDA Cornalin DOC is in progress.
