8.2 Austria, Switzerland & Central European Wine

Austria, Switzerland & Central European Wine

Core Sommelier Competency: For the Court of Master Sommeliers (CMS) Certified Sommelier Examination, candidates must demonstrate thorough theoretical knowledge and tableside familiarity with the wines of Austria, Switzerland, Hungary, and neighboring Central European regions. Candidates must fluently explain the Austrian quality pyramid and DAC system, detail the three traditional Wachau quality tiers (Steinfeder, Federspiel, Smaragd), describe the unique field-blend regulations of Wiener Gemischter Satz DAC, outline Switzerland's key cantons and signature grape varieties (such as Chasselas/Fendant, Petite Arvine, and Ticino Merlot), and articulate the vinification and modern legal standards of Hungarian Tokaji Aszú.

Central European viticulture combines profound historical heritage with some of the most rigorous contemporary quality standards in the global wine trade. From the terraced Danube river cliffs of Austria to the high alpine valleys of Switzerland and the volcanic slopes of Hungary's Tokaj, this region produces world-class cool-climate wines defined by crystalline acidity, mineral complexity, and unmistakable varietal precision.

1. Austria: Quality Revolution, Wine Laws & The DAC System

The 1985 Glycol Scandal & Quality Rebirth

In 1985, a small number of Austrian bulk-wine brokers were caught adulterating low-grade wine with diethylene glycol (a toxic compound used in antifreeze) to artificially enhance body, sweetness, and apparent extract. The immediate global embargo devastated Austrian wine exports but catalyzed the most aggressive legislative transformation in modern wine history.

Austria enacted the strictest wine laws in the world, introducing mandatory chemical batch tracking, strict yield limits, state inspection seals (Banderole), and an unwavering national commitment to dry, estate-bottled, terroir-driven fine wines.

+-----------------------------------------------------------------------------+

Must Weight Measurement: The KMW Scale

Austrian must weight is measured using the Klosterneuburger Mostwaage (°KMW) scale, developed by August Wilhelm von Babo at the Klosterneuburg Viticultural Institute.

$\text{1 °KMW} \approx 1.2\text{ °Oechsle (°Oe)} \approx 0.25\% \text{ sugar by weight}$

Austrian Prädikat Categories & Kabinett Distinction

Unlike German wine law, in Austria Kabinett is classified as a sub-tier of Qualitätswein, not a Prädikatswein:

• Kabinett (Qualitätswein): Minimum must weight of 17 °KMW (~85 °Oe); maximum residual sugar 9 g/L; minimum alcohol 11.0% ABV. Chaptalization is strictly forbidden.
• Spätlese (Prädikat): Minimum 19 °KMW (~95 °Oe); fully ripe grapes, dry or sweet.
• Auslese (Prädikat): Minimum 21 °KMW (~105 °Oe); unripe berries removed.
• Beerenauslese (BA): Minimum 25 °KMW (~125 °Oe); overripe/botrytized berries.
• Eiswein: Minimum 25 °KMW; harvested and pressed while frozen solid on the vine.
• Strohwein / Schilfwein: Minimum 25 °KMW; ripe grapes dried on straw mats (Stroh) or reeds (Schilf) for a minimum of three months prior to pressing, concentrating natural sugars.
• Trockenbeerenauslese (TBA): Minimum 30 °KMW (~150 °Oe); shriveled botrytis-affected grapes.

The DAC (Districtus Austriae Controllatus) Appellation System

Introduced in 2002 (effective with the 2003 vintage of Weinviertel), the DAC system transitioned Austrian wine from a purely sugar-based hierarchy to a French/Italian origin-based appellation model protecting regional typicity. Each DAC establishes authorized grape varieties, minimum alcohol levels, flavor profiles, and a three-tier quality pyramid:

1. Gebietswein (Regional Wine): Broad regional expression.
2. Ortswein (Village Wine): Sourced from specific communes; higher minimum ripeness.
3. Riedenwein (Single Vineyard Wine): Sourced from a registered single vineyard (Ried); highest quality and concentration.

2. Austrian Wine Regions & The Wachau Classification

Austria possesses approximately 45,000 hectares of vineyards divided across four main federal wine-growing states (Weinbaugebiete):

+-----------------------------------------------------------------------------+

The Wachau & The Vinea Wachau Quality Tiers

The Wachau is a dramatic 33-kilometer UNESCO World Heritage stretch of the Danube River between Melk and Krems. Steep, south-facing terraced vineyards are carved into primary crystalline rock (Gföhler gneiss, amphibolite, and mica-schist) layered with loess deposits.

In 1983, local growers formed the Vinea Wachau Nobilis Districtus, establishing a strict codex for dry, un-chaptalized white wines (Grüner Veltliner and Riesling) classified into three iconic tiers based on natural potential alcohol:

(Note: In 2020, the Wachau formally joined the statutory DAC system as Wachau DAC, integrating its Gebietswein, Ortswein, and Riedenwein structure while legally preserving the Vinea Wachau Steinfeder/Federspiel/Smaragd designations on labels).

• Iconic Wachau Crus (Rieden): Achleiten (Weissenkirchen - dark amphibolite and gneiss; mineral, smoky), Singerriedel (Spitz - steep mica-schist; monumental Riesling), Kellerberg (Dürnstein), Höhereck, Loibenberg (warmer, rich, tropical).

Other Key Niederösterreich DACs

• Kremstal DAC & Kamptal DAC: Bordering the Wachau along the Krems and Kamp rivers. Kamptal is anchored by the town of Langenlois and the legendary Heiligenstein vineyard (volcanic Permian desert sandstone producing electric, age-worthy Riesling), alongside massive loess terraces (such as Lamm and Grub) for rich Grüner Veltliner.
• Traisental DAC: Cool, high-calcareous limestone soils producing bone-dry, chalky Grüner Veltliner and Riesling.
• Weinviertel DAC: Austria's largest single wine region; the first DAC created (2003). Dedicated 100% to crisp, peppery Grüner Veltliner ("pfeffrig").
• Wagram: Rolling hills east of Krems covered with deep glacial loess deposits; renowned for rich, round Grüner Veltliner and the rare indigenous Roter Veltliner.
• Carnuntum DAC: Located southeast of Vienna along the Danube; warm Pannonian breezes produce spicy, structured red wines dominated by Zweigelt and Blaufränkisch.
• Thermenregion: South of Vienna; historic thermal spring region famed for indigenous white varieties Zierfandler (Spätrot) and Rotgipfler (often blended as Spätrot-Rotgipfler) alongside Pinot Noir and St. Laurent.

Burgenland & The Noble Sweet Wines of Rust

Burgenland borders Hungary and is dominated by the shallow, expansive Lake Neusiedl (Neusiedlersee). The warm Pannonian plain climate combined with high autumn humidity from the lake creates ideal morning fogs, promoting consistent annual noble rot (Botrytis cinerea).

+-----------------------------------------------------------------------------+

Steiermark (Styria) & Wien (Vienna)

• Steiermark (Styria): Austria's green alpine south, famous for steep, dramatic hillsides. Divided into three DACs: Südsteiermark DAC (world-renowned, mineral, grass/elderflower-scented Sauvignon Blanc and Morillon / Chardonnay), Vulkanland Steiermark DAC (volcanic basalt soils), and Weststeiermark DAC (home of Schilcher, an intensely tart, high-acid, raspberry-scented rosé made from the ancient native grape Blauer Wildbacher).
• Wien (Vienna) & Wiener Gemischter Satz DAC: Vienna is the only world capital with an economically significant wine appellation within its city boundaries (~580 ha). It is famed for Wiener Gemischter Satz DAC, a traditional field blend: at least three white grape varieties must be planted together in the vineyard, harvested simultaneously, and co-fermented (the largest variety cannot exceed 50%, and the third variety must comprise at least 10%).

3. Switzerland (Suisse / Schweiz): Alpine Terroir & Cantons

Switzerland produces some of the world's most refined alpine wines, though less than 2% of total production is exported internationally due to high domestic demand. Viticulture is defined by dramatic elevations, glacial soils, alpine river valleys, and moderating lake influences.

Key Swiss Wine Terms & Benchmark Styles

• Chasselas (Fendant / Dorin): Switzerland's premier native white grape. In the Valais, it is termed Fendant (referring to how the ripe berry splits or "fends" under finger pressure); in Vaud, it is historically called Dorin. Yields delicate, refreshing, mineral-driven dry white wines with subtle notes of white flowers, flint, pear, almond, and a gentle natural carbonic spritz.
• Dôle: A protected Valais red blend requiring a minimum of 85% combined Pinot Noir and Gamay (with Pinot Noir predominating), complemented by permitted local varieties such as Syrah, Cornalin, or Humagne Rouge.
• Oeil-de-Perdrix: "Eye of the Partridge"; a delicate, pale salmon-colored rosé invented in the canton of Neuchâtel, produced via short skin-contact maceration of 100% Pinot Noir.
• Vin du Glacier: A traditional oxidative white wine from the high Valais (Val d'Anniviers), crafted from the indigenous Rèze grape matured in high-altitude alpine cellars using a solera-like larch-wood barrel system.

4. Hungary: Tokaj-Hegyalja & Central European Benchmarks

Tokaj-Hegyalja: History, Terroir & Botrytis

Located in northeastern Hungary along the slopes of the Zemplén Mountains at the confluence of the Tisza and Bodrog rivers, Tokaj is one of the world's most historic wine regions. In 1737, Tokaj was formally demarcated by royal decree, establishing what is widely recognized as the world's first formal vineyard classification system.

• Climate & Botrytis: Warm, sunny continental summers give way to long, humid autumns. Morning mists generated by the rivers roll across south-facing slopes, followed by warm daytime breezes—the ideal microclimatic engine for noble rot (Botrytis cinerea, locally termed nemes rohadás).
• Soils: Volcanic bedrock composed of rhyolite, andesite, and volcanic tuff, overlaid with clay and wind-blown loess.

The Vinification of Tokaji Aszú

Traditional Tokaji Aszú production is an intricate, multi-stage winemaking craft unlike any other sweet wine in the world:

[1. ASZÚ HARVEST] --> Harvesters pick botrytized shriveled berries individually
                      by hand in wooden tubs called PUTTONYOS (~25 kg / 55 lbs).
      |
      v
[2. ASZÚ PASTE]   --> Botrytized Aszú berries are crushed into a thick, doughy
                      paste ('Aszú tészta') in the winery.
      |
      v
[3. MACERATION]   --> The Aszú paste is steeped in a standard 136-liter barrel
                      ('GÖNCI' barrel) of base dry wine or fermenting must for
                      24 to 48 hours to extract sugars, noble botrytis, and acid.
      |
      v
[4. PRESSING &    --> The enriched mixture is pressed, racked into oak barrels,
    FERMENTATION]     and undergoes a secondary, slow alcoholic fermentation.
      |
      v
[5. CELLAR AGING] --> Matured in deep underground labyrinth cellars carved into
                      volcanic tuff, coated with black fungus (Cladosporium cellare)
                      which regulates humidity and purifies the cellar air.

The Puttonyos Scale & Modern Regulations

Historically, the sweetness and richness of Tokaji Aszú were measured by how many puttonyos (baskets) of Aszú paste were added to a 136-liter Gönci barrel of base wine, ranging from 3 Puttonyos (min. 60 g/L RS) up to 6 Puttonyos (min. 150 g/L RS).

[!IMPORTANT] The 2013 Tokaj Legislative Reform: To protect quality and eliminate diluted styles, the Hungarian wine authorities abolished the 3 and 4 Puttonyos categories for Aszú. Under modern regulations:

• Tokaji Aszú must contain a minimum of 120 g/L residual sugar (the equivalent concentration of the former 5 Puttonyos tier).
• Tokaji Aszú 6 Puttonyos must contain a minimum of 150 g/L residual sugar.
• Mandatory Aging: All Tokaji Aszú must undergo a minimum of 18 months aging in oak barrels and cannot be commercially released until the third year after harvest.

Other Iconic Tokaj Styles

• Tokaji Eszencia (Essencia): The rarest, most concentrated liquid nectar on Earth. Made entirely from the tiny amount of free-run juice that naturally drains from vats of botrytized Aszú berries under the gentle force of their own gravity without mechanical pressing. Sugar levels reach astronomical heights (minimum 450 g/L residual sugar, often 500–800 g/L), so dense that yeast can barely ferment it. Fermentation takes years to reach 1.2% to 6.0% ABV. Traditionally served directly from crystal spoons.
• Tokaji Szamorodni: "As it comes"; harvested from whole bunches containing a natural mix of healthy and botrytized grapes. Produced in two styles: Száraz (Dry, fermented fully dry, aged under a veil of flor yeast similar to Sherry) and Édes (Sweet, minimum 45 g/L RS).
• Dry Furmint: A modern fine-wine movement pioneered by István Szepsy and Királyudvar; crisp, smoky, mineral dry white wine aged in Hungarian oak.

Other Central European Highlights

• Hungary (Other Regions): Eger (famed for Egri Bikavér / "Bull's Blood", a structured red blend based on Kékfrankos / Blaufränkisch, Kadarka, and Bordeaux varieties), Villány (warm southern red region famous for world-class Cabernet Franc and Kékfrankos), and Somló (an isolated volcanic basalt hill producing smoky, high-acid dry Furmint and Juhfark).
• Slovenia: Divided into Primorska (bordering Italy's Collio; famous for Rebula/Ribolla Gialla, Sauvignonasse, and skin-contact orange wines in Goriška Brda) and Podravje (northeastern white wine center for Furmint / Šipon and Riesling).
• Czech Republic (Moravia): Cool continental climate bordering Austria; produces crisp Grüner Veltliner (Veltlínské Zelené), Ryzlink Rýnský, and Saint Laurent (Svatovavřinecké).
