Grape field guide · dark-skinned
Cornalin has a party trick: it can turn black cherry, blueberry, violet into something that tastes of a place rather than a fruit bowl. Start with structured dry red, notice the acidity and weight, and only then decide what sort of character has actually joined you at the table.
The grape story
Known in Valais as Cornalin, this Alpine variety is genetically identical to the grape called Rouge du Pays and distinct from the Cornalin d'Aoste of Italy's Aosta Valley.
Its home territory: Valais, Switzerland.
In the glass
These are useful recurring possibilities. Climate, yield, harvest date, fermentation, extraction, maturation, bottle age, and serving conditions can all move the result.
In the vineyard
Irregular yields and late ripening make it demanding; sunny, warm Valais sites help develop colour and tame firm tannin.
Common expressions
Variety does not dictate method. Skin contact, whole bunches, pressing, fermentation vessel, yeast, oxygen, oak, lees, sweetness, fortification, and bubbles can transform the same fruit.
Blending partners
A blend is not a hiding place for leftovers. Each grape can be asked to supply fruit, perfume, acidity, tannin, colour, body, or simply a better answer to an awkward vintage.
Cornalin appears here alongside Chasselas, Pinot Noir, Gamay, Petite Arvine, Humagne Rouge. That does not mean every bottle is blended; it tells you which local grapes can provide useful contrasts in fruit, structure, and ripening.

Markers combine dedicated World Explorer profiles with audited benchmark areas important to Cornalin. This is a teaching map of major associations—not a census of every planting.
Try this at home
Put Cornalin beside Chasselas. Do not play “guess the grape.” Compare acidity, tannin or phenolic grip, body, aroma intensity, and the length of the finish. The useful answer is not which one you prefer, but what created the difference.
Keep digging
Historical names, vineyard collections, official records, and modern research do not always agree neatly. These are starting points for checking the parts of the story that matter for this grape.
