Fendant (Chasselas in Valais)

Chasselas appears in Valais written records dating to 1627, though major cultivation only took off in the 19th century. Popularity rose dramatically in the mid-1800s, and by 1991, when the AOC system was introduced, Fendant covered over 1,875 hectares, representing more than 35% of all Valais vineyards. The shift to AOC regulation was deliberately aimed at emphasizing quality over quantity, a goal reflected in the grape's reduced but more focused footprint today. DNA research has definitively confirmed the variety originated near Lake Geneva in western Switzerland.

• First documented in Valais records in 1627; major cultivation began in the 19th century
• AOC Valais established in 1991 to prioritize quality over volume production
• By 1991, Fendant represented over 35% of Valais vineyard area; now approximately 17%
• DNA research places the variety's origin near Lake Geneva, not in the Middle East as older theories suggested

Valais is one of Switzerland's driest and sunniest wine regions, sheltered by surrounding mountains that create warm, steppe-like conditions in the upper valley. Vineyards sit between 400 and 800 meters above sea level, with the extraordinary Visperterminen plots climbing to 1,150 meters, among the highest in Europe. Foehn wind effects produce strong thermal amplitudes between day and night in autumn, supporting the early-ripening Chasselas grape. Soils vary considerably across the appellation, encompassing clay, limestone, calcareous terroir, and mineral-rich compositions; chalky soils in particular contribute to the characteristic minerality in the finished wines.

• Dry, sunny, mountain-sheltered climate with warm steppe conditions in the upper Valais
• Elevation range of 400 to 1,150 meters, offering diverse growing conditions
• Foehn winds create strong day-to-night temperature variation in autumn
• Diverse soils including clay, limestone, and chalky mineral-rich compositions

Fendant produces dry, light-bodied white wines typically sitting at 9 to 10% alcohol. The wines display a velvety texture alongside fresh fruity aromas, and a slight natural effervescence gives them a playful, lively quality on the palate. Mineral notes reflect the varied soils of the Valais, and the grape's natural adaptability means expressions can range from floral and fruity to stony and austere depending on the specific terroir. Fendant is best consumed young, within two to three years of vintage, and is ideally served chilled between 8 and 12 degrees Celsius.

Fendant falls under the AOC Valais framework, Switzerland's Appellation d'Origine Contrôlée system introduced in 1991. A Grand Cru system also operates in select areas of Valais for wines meeting higher quality thresholds. The global benchmark for Chasselas quality is the Mondial du Chasselas, an annual competition held at Château d'Aigle in Valais and recognized as the most important award for wines made from this variety. Fendant remains the most popular white wine of Valais and Switzerland's most widely produced white grape variety in the region.

• AOC Valais classification established in 1991 governs production standards
• Grand Cru designation available in select Valais subzones
• Mondial du Chasselas at Château d'Aigle is the world's leading Chasselas competition
• Fendant is the most popular white wine produced in Valais
