Cornalin is a rare and prized black grape variety from the Aosta Valley, with roots in the history of Alpine viticulture and documented in the region as early as the 19th century. Its identity has also been clarified through ampelographic and genetic studies, which trace it back to Humagne rouge grown in the Swiss canton of Valais, where it is also known as Rouge du Pays. It is found primarily in the vineyards of the Aosta Valley, set amongst the steep terraces and on the sun-facing slopes of the valley, whilst across the border it thrives in the wine-growing areas of Valais.
From an ampelographic perspective, it produces a medium-sized bunch, generally cylindrical or conical in shape, sometimes with one or two wings, and of medium compactness. The berry is medium-sized, globular, with a thick, blue-black skin, whilst the flesh is lightly pigmented. The mature leaf is pentagonal, three-lobed or five-lobed, with a petiole sinus varying from open to closed and an almost hairless underside.
The wine is characterised by an intense ruby-red colour, sometimes enhanced by violet hues, and by a fragrant aromatic profile, dominated by dark berries, black cherry, spices and delicate notes of clove. On the palate, it offers freshness, good structure, tension and tannins that are present yet harmonious. The natural acidity and tannic structure promote positive development in the bottle, during which the fruit becomes more refined and the wine gains elegance and smoothness.
