Overview
Switzerland has 14,569 hectares of vineyards worked by more than 2,500 producers, with annual production of roughly one million hectolitres. Less than 2 percent of Swiss wine is exported; the rest is absorbed by the domestic market. Production is organized into six regions: Valais, which holds almost a third of the national vineyard; Vaud, the second largest; Geneva, the third largest wine canton; Ticino, south of the Alps; the Three Lakes (Neuchâtel, Lake Biel and Vully); and German-speaking Switzerland, whose vineyards are scattered across sixteen cantons. Wine law operates at the cantonal level, so appellation rules differ from canton to canton.
History
Viticulture in Switzerland dates to the Roman period. The terraced vineyards of Lavaux on Lake Geneva were built from the eleventh and twelfth centuries under the bishops of Lausanne and Cistercian monks, and were inscribed on the UNESCO World Heritage List in 2007. The national vineyard peaked at roughly 35,000 hectares in the mid-nineteenth century, then contracted under successive arrivals of powdery mildew (1851), phylloxera and downy mildew (both 1885), and competition from imported wine. In Ticino, where phylloxera had destroyed the local vineyard, Merlot was introduced in 1906 on the Vallombrosa estate of Giovanni Rossi at Castelrotto and became the canton's defining variety. The federal research station at Changins shaped the modern vineyard through breeding: André Jaquinet's 1970 crossings of Gamay and Reichensteiner produced the sibling red varieties Gamaret and Garanoir, and in 2013 Agroscope released Divico (Gamaret x Bronner), its first fungus-resistant red variety. Geneva became the first canton to introduce a formal AOC system, in 1988, and the other cantons followed.
Terroir & Climate
Valais occupies the inner-alpine valley of the upper Rhône, one of the driest zones in the country, warmed by the foehn wind; its steep terraces include some of Europe's highest vineyards, reaching about 1,150 metres at Visperterminen. Vaud's vineyards line Lake Geneva in Lavaux and La Côte and extend to the Chablais, with the lake moderating temperatures on the terraces. The Three Lakes region grows vines on limestone soils at the foot of the Jura. In German-speaking Switzerland the most concentrated quality zone is the Bündner Herrschaft in Graubünden (the villages of Fläsch, Maienfeld, Jenins and Malans), a foehn-warmed corridor of the Alpine Rhine valley. Ticino, on the southern side of the Alps, is markedly wetter, and Merlot occupies over 80 percent of its vineyard surface.
Grape Varieties & Wine Styles
Pinot Noir is the most planted variety and Chasselas the leading white; together they account for roughly half the national vineyard. Chasselas changes name by canton: Fendant in Valais and Perlan in Geneva. Gamay, Merlot and Müller-Thurgau follow. Valais maintains a range of specialties, including Petite Arvine, Amigne, Heida (Savagnin) and Ermitage (Marsanne) among whites, and Cornalin and Humagne Rouge among reds; Dôle, the traditional Valais red, blends Pinot Noir with Gamay. Graubünden preserves the old white variety Completer, and Zurich grows Räuschling. Neuchâtel is the origin of the Oeil-de-Perdrix style of Pinot Noir rosé. Vaud maintains two AOC Grand Crus, Dézaley and Calamin, both Chasselas terraces in Lavaux.
Notable Producers
In the Bündner Herrschaft: Gantenbein in Fläsch, founded in 1982 by Daniel and Martha Gantenbein, and Donatsch in Malans, in its fifth generation with Pinot Noir, Chardonnay and Completer. In Valais: Marie-Thérèse Chappaz in Fully, who took over the family estate in 1987; Jean-René Germanier in Vétroz, producer of the Cayas Syrah; and Provins, the country's largest producer, drawing grapes from about 750 hectares. In Vaud: Louis Bovard in Cully, a reference for Dézaley Chasselas. In Ticino: Gialdi in Mendrisio, founded in 1953 and incorporating Brivio since 2001, and Vinattieri Ticinesi, founded in 1985 by Luigi Zanini.
What to Know
Because appellations are cantonal, identical terms can carry different requirements in different cantons, and the AOC name signals origin more than a uniform standard. Export volumes are negligible, so allocation and price, not scoring, are the practical constraints on buying. Chasselas is the category to understand for whites: a low-aromatic variety whose value lies in site transparency, at its most structured in Dézaley. For reds, Graubünden Pinot Noir, Valais specialties and Ticino Merlot are the three benchmarks.
