To get to know Valais wine, start with the grapes you will hardly find anywhere else: Petite Arvine for whites, Cornalin and Humagne Rouge for reds. Valais is Switzerland's largest wine canton, with 4,578 hectares of vines in 2025 according to the Federal Office for Agriculture (FOAG), close to a third of the country's vineyards.
The vineyards follow the Rhône from Port-Valais on Lake Geneva up to Brig, across more than sixty wine-growing communes, says Swiss Wine Valais, the canton's wine trade body. Pinot Noir and Fendant, the local name for the Chasselas grape, are the most planted.
Where are the Valais vineyards?
The vines cling to the slopes of the Rhône valley, often on terraces held up by dry stone walls. Swiss Wine Valais divides the area into three parts: Lower Valais, from Port-Valais to Leytron; Central Valais, from Chamoson to Sierre; and German-speaking Upper Valais, from Salgesch to Brig.
The vines climb high. According to Swiss Wine Promotion, the body that promotes Swiss wine, they reach 1,100 metres at Visperterminen, above Visp. In 2025 the FOAG counted 4,578 hectares of vines in Valais, 38 fewer than in 2024; the canton remains by far the largest, ahead of Vaud.
Why does the Valais climate suit vines so well?
Valais is a dry valley sheltered from rain by the Alps. Swiss Wine Promotion puts rainfall at about 650 mm and sunshine at 2,500 hours a year. Little rain means fewer fungal diseases on the grapes: Swiss Wine Valais notes that the climate naturally keeps mildew and rot in check.
In autumn the foehn blows, a warm, dry wind coming down from the mountains. It extends the ripening of late varieties such as Petite Arvine and Cornalin, which need a long autumn.
The terraces matter too. Swiss Wine Valais explains that the dry stone walls hold the soil, slow erosion and create many small microclimates, while lizards and insects live in the gaps. On these slopes, nearly all the work is still done by hand.
Which grapes should you try in Valais?
Valais is mostly red-wine country: 58% of the area, according to the FOAG. Pinot Noir leads with 1,222 hectares, a third of all Swiss Pinot Noir. Blended with Gamay, it makes Dôle, the canton's traditional red.
Among whites, Fendant dominates. It is drunk young and fresh, with raclette or as an aperitif. Johannisberg, the Valais name for Sylvaner, is the second white grape. Swiss Wine Valais describes it as richer and denser than Fendant, with notes of peach, flint and honey; it ripens very late and needs the warmest plots.
What sets Valais apart are its specialities. FOAG figures show that over 99% of Switzerland's Petite Arvine, Cornalin, Humagne Rouge and Amigne grows here. Petite Arvine makes a lively white with citrus notes and a salty finish; Cornalin a velvety, fruity red. Heida (also called Païen, the Valais name for Savagnin Blanc), Syrah and Humagne Blanche complete the range. Swiss Wine Valais counts 55 grape varieties allowed under the AOC.
Our pages on Petite Arvine, Cornalin, Humagne Rouge, Heida and Fendant cover each grape in detail, with planted areas and food pairings.
What do AOC Valais and Grand Cru guarantee?
Every appellation wine from the canton carries the words AOC Valais. AOC stands for appellation d'origine contrôlée, a protected designation of origin: the grapes come from a defined area and follow a set of rules on permitted varieties, maximum yields and minimum sugar content. Swiss Wine Valais points out that the cantonal wine ordinance requires this to appear clearly on the front label.
Grand Cru goes further. It is voluntary and run by ten communes, each choosing which grapes may be grown on its best plots. The rules, as set out by Swiss Wine Valais: vines at least 8 years old, lower yields, higher natural sugar than standard AOC, winemaking and bottling in Valais, and approval every year by a tasting panel.
The ten communes and their Grand Cru grapes: Chamoson (Johannisberg, Petite Arvine, Pinot Noir, Syrah), Conthey (Fendant, Heida, Pinot Noir, Cornalin), Leytron (Fendant, Humagne Blanche, Humagne Rouge, Cornalin), Saillon (Petite Arvine, Humagne Rouge, Cornalin, Syrah), Salgesch (Pinot Noir, Dôle, Cornalin, Syrah), Sierre (Petite Arvine, Ermitage, Cornalin, Syrah), Sion (Fendant, Ermitage, Dôle, Syrah), Saint-Léonard (Fendant, Pinot Noir), Vétroz (Fendant, Amigne, Pinot Noir, Gamay) and Visperterminen (Heida). Ermitage is the Valais name for Marsanne, a white grape.
Which villages and landscapes are worth a visit?
The Vineyard Trail (Chemin du vignoble) crosses the wine country from Martigny to Leuk over more than 65 kilometres, in four stages: Branson–Saillon, Saillon–Sion, Sion–Venthône and Venthône–Leuk, according to Valais/Wallis Promotion, the canton's tourist board. Stations at Martigny, Sion, Sierre, Salgesch and Leuk make it easy to walk one day at a time.
Above Sion, the Bisse de Clavau path follows an old irrigation channel through the terraces; that is the view in the photo at the top of this page. Vétroz is the home of Amigne, Fully the village of brisolée, an autumn meal of roasted chestnuts, Visperterminen the village of mountain vines.
Where can you taste Valais wine?
The Valais Open Cellars (Caves ouvertes) take place every year over the Ascension weekend. Swiss Wine Valais says it started in 2007 with 99 cellars; today more than 230 open their doors, with shuttle buses linking some villages.
All year round, the Valais Vine and Wine Museum tells the story of the vineyards at two sites: the Wine Museum in Sierre for temporary exhibitions and the Zumofen House in Salgesch for the permanent one. An 8-kilometre vineyard path joins them, with panels on the grapes; it hosts the Marche des cépages, a wine walk that draws up to 9,000 visitors according to Swiss Wine Valais.
