Humagne Rouge & Cornalin du Valais: Rare Indigenous Valais Reds

Cornalin du Valais originated in the Aosta Valley as a cross between Mayolet and Petit Rouge, making its way to Switzerland's Valais via the Great Saint Bernard pass in the early 20th century. Known locally as Rouge du Pays, it became one of the region's principal red varieties before phylloxera and competition from modern varieties pushed it to the brink of disappearance by the 1970s. A revival effort in that same decade saved the variety and established the name Cornalin. Humagne Rouge followed a similar arc, first documented around 1900 in the village of Fully. By the 1960s, only 5 to 6 vine parcels survived. Revived in the 1980s, Humagne Rouge was later confirmed by DNA analysis to be identical to Cornalin d'Aoste from the Aosta Valley, revealing its shared heritage with its Valais counterpart.

• Cornalin du Valais is a cross of Mayolet and Petit Rouge, originating in the Aosta Valley
• Both varieties nearly vanished due to phylloxera and competition from higher-yielding modern grapes
• Humagne Rouge is genetically an offspring of Cornalin du Valais and an unknown parent
• DNA testing confirmed Humagne Rouge and Cornalin d'Aoste are identical varieties

The Valais region sits in a dramatic Alpine valley, with vineyards ranging from 270 to 1,100 metres above sea level and most planted between 450 and 850 metres. The continental Alpine climate delivers 2,000 to 2,500 hours of annual sunshine and 550 to 700mm of rainfall, supported by warm föhn winds that aid ripening. Soils shift from granite, gneiss, and schist in the Upper Valais to limestone, marl, and glacial alluvium in the Lower Valais. Both Cornalin du Valais and Humagne Rouge are late-ripening varieties demanding warm exposures and the best sites. Humagne Rouge is harvested more than three weeks after Fendant, reflecting just how long it needs to reach full maturity.

• Both varieties are late-ripening and require prime sites and warm exposures

Cornalin du Valais produces deeply colored, fruit-forward red wines with silky tannins and aromas of cherry, raspberry, and violet. It is considered one of the main drivers of Valais red wine identity, alongside Petite Arvine. Humagne Rouge takes a more rustic character, with firm tannins and aromas of wild fruit, violet, and undergrowth. Winemakers sometimes use a traditional technique of cutting the fruit branches 5 to 10 days before harvest, which concentrates the sugars and flavors in the grapes. Though the names suggest a relationship, Humagne Rouge and Humagne Blanche share no genetic connection.

• Cornalin du Valais: deep color, silky tannins, cherry, raspberry, and violet aromas
• Humagne Rouge: rustic, firm tannins, wild fruit, violet, and undergrowth character
• Traditional branch-cutting technique concentrates fruit in Humagne Rouge before harvest
• Humagne Rouge and Humagne Blanche are unrelated despite sharing a name

The Valais AOC encompasses approximately 4,800 to 5,200 hectares of vines, and several producers have been instrumental in championing these indigenous varieties. Adrian and Diego Mathier, Provins, and Philippe Varone are among the notable names working with both Cornalin du Valais and Humagne Rouge. Their commitment has helped establish these once-endangered grapes as a source of regional pride and genuine quality in the modern Swiss wine landscape.

• Valais AOC covers approximately 4,800 to 5,200 hectares total
• Adrian and Diego Mathier, Provins, and Philippe Varone are leading producers
• These producers have been central to the revival and promotion of both varieties
