TBA and Eiswein from Burgenland: Austria's Premium Sweet Wines

Alois Kracher Sr. (1928–2010) laid the foundations for the Weinlaubenhof in Illmitz, pressing quality sweet wines from noble-rot grapes at a time when this was far from commonplace in the Seewinkel. His son, Alois Kracher Jr. (1959–2007), known as 'Luis', joined the winery part-time in 1981 and switched to full-time winemaking in 1986, rapidly transforming the estate into a global reference point for botrytized wine. The 1991 vintage brought Kracher his first sustained international acclaim, introducing two distinct TBA styles: the reductive, tank or large-cask-aged 'Zwischen den Seen' and the barrique-fermented 'Nouvelle Vague'. Luis died of pancreatic cancer in December 2007 at the age of 48. His son Gerhard Kracher (born 1981), who had been working in the family business since 2001, took over management and won the International Wine Challenge Sweet Winemaker of the Year award in 2009. Austria joined the EU in 1995, boosting international market access, and the DAC system for regional typicity was launched in 2003.

• Alois Kracher Sr. (1928–2010) pioneered quality sweet wine production in the Seewinkel from the mid-20th century
• Alois Kracher Jr. worked part-time from 1981, full-time from 1986; the 1991 vintage was his first to earn broad international acclaim
• Two TBA styles introduced: Zwischen den Seen (stainless steel or large oak) and Nouvelle Vague (French oak barriques)
• Gerhard Kracher has managed the estate since 2007 and won the IWC Sweet Winemaker of the Year award in 2009

Lake Neusiedl, the largest steppe lake in Central Europe, sits at the heart of the Neusiedlersee wine region and exerts a profound moderating influence on the surrounding vineyards. With an average depth of just over one meter, the shallow lake heats up during summer days and releases warmth at night, while generating dense autumn mists that are subsequently burned off by afternoon sunshine. This alternation of morning humidity and afternoon dryness is precisely the cycle that allows Botrytis cinerea to develop in a controlled, beneficial manner rather than causing destructive grey rot. The Seewinkel sub-region to the south and east of the lake, including the villages of Illmitz, Apetlon, and Podersdorf, also contains numerous small salt-water lakes known as 'Zicklacken', which further raise humidity and deepen the botrytis-friendly microclimate. The region sits within the Pannonian climate zone, characterized by hot, dry summers and cold winters, and enjoys around 300 days of sunshine annually.

• Lake Neusiedl is the largest steppe lake in Central Europe, averaging just over one meter in depth, generating autumn mists that alternate with afternoon sun
• Pannonian climate: hot, dry summers with moderate rainfall, cold winters with little snow; around 300 days of sunshine annually
• Seewinkel's small saline lakes, the 'Zicklacken', amplify humidity and promote consistent noble rot development around Illmitz, Apetlon, and Podersdorf
• The lake acts as a heat reservoir in summer, gently cooling vineyards at night and preserving fruit acidity essential for balanced sweet wines

Welschriesling is the benchmark grape for Neusiedlersee DAC Reserve sweet wines. Unrelated to Rhine Riesling, it is highly susceptible to Botrytis cinerea and produces wines with pronounced acidity that balances high residual sugar, yielding layered aromas of quince, honey, and citrus. Chardonnay, Scheurebe, Traminer, and Muskat-Ottonel are also widely used for TBA production, with Weinlaubenhof Kracher crafting between 10 and 15 different TBA cuvées annually from this range of varieties. Furmint, historically associated with the town of Rust and its Ausbruch tradition, reflects a link with neighboring Tokaj in Hungary, though it now plays only a minor role in the region. Eiswein is typically produced from healthy, botrytis-free grapes including Welschriesling, Grüner Veltliner, Traminer, and Riesling, relying on freeze concentration rather than noble rot to achieve its piercing, high-acid sweetness. Climate change is making reliable Eiswein harvests increasingly difficult in Burgenland.

• Welschriesling is the primary variety for Neusiedlersee DAC Reserve nobly sweet wines; its high natural acidity balances concentrated residual sugar
• Kracher uses Welschriesling, Chardonnay, Scheurebe, Traminer, and Muskat-Ottonel for TBA, plus occasionally Zweigelt for red-grape TBAs
• Furmint has a historic presence in Rust's Ausbruch tradition but now plays only a minor role in Burgenland sweet wine production overall
• Eiswein grapes should be healthy and free of botrytis; varieties include Welschriesling, Grüner Veltliner, Riesling, and Traminer

Weinlaubenhof Kracher in Illmitz is the most internationally celebrated producer of Austrian TBA. Alois Kracher Jr. established the estate's reputation by demonstrating that Austrian sweet wines could rival the finest Sauternes, famously organizing comparative tastings against Château d'Yquem in 1988 and later in London in 1993. Each vine at Kracher is limited to just three bunches, individual parcels are vinified separately in lots sometimes as small as 100 liters, and malolactic fermentation is avoided to preserve natural acidity. Gerhard Kracher continues these exacting standards, with the 2022 vintage TBA range earning 96–98 points from the Wine Advocate. Other notable Seewinkel producers of sweet wines include Angerhof Tschida (Welschriesling TBA specialist) and Gebrüder Nittnaus. On the western shore of Lake Neusiedl, the historic free city of Rust is home to Ruster Ausbruch, which received its own DAC designation in 2020, with Heidi Schröck among its most acclaimed producers.

• Kracher produces 10–15 TBAs annually across two styles: Zwischen den Seen (steel or large oak) and Nouvelle Vague (French oak barriques)
• Alois Kracher Jr. organized comparative tastings against Château d'Yquem in 1988 and 1993, establishing Austrian TBA's international credibility
• The 2022 Kracher TBA range scored 96–98 points from Wine Advocate, confirming the estate's continued excellence under Gerhard Kracher
• Ruster Ausbruch gained its own DAC designation in 2020; Heidi Schröck is among the most respected Ausbruch producers in Rust

Austrian Prädikatswein classification is based on the Klosterneuburg Must Weight (KMW) scale, where 1° KMW equals approximately 5° Oechsle. Beerenauslese requires a minimum of 25° KMW and must be produced from botrytis-affected berries. Eiswein also requires 25° KMW, but differs fundamentally: grapes must be healthy, naturally frozen on the vine, and harvested and pressed at temperatures of -7°C or below, so that water remains as ice and only concentrated juice is extracted. Trockenbeerenauslese sits at the pinnacle, requiring a minimum of 30° KMW (approximately 150° Oechsle). The higher the must weight, the more difficult fermentation becomes; TBA fermentations can take many months and often yield only modest alcohol. Austria's DAC (Districtus Austriae Controllatus) system began in 2003. The Neusiedlersee DAC was introduced for the 2012 vintage; from 2020, sweet wines were also permitted to carry the DAC designation, with Beerenauslese and TBA labeled as Neusiedlersee DAC Reserve.

• TBA minimum = 30° KMW (approximately 150° Oechsle); Beerenauslese and Eiswein minimum = 25° KMW (approximately 127° Oechsle); 1° KMW = approximately 5° Oechsle
• Eiswein harvest requires temperatures of -7°C or lower; grapes must be naturally frozen on the vine and pressed frozen so water is removed as ice
• Austria's DAC system launched in 2003; Neusiedlersee DAC established for the 2012 vintage; sweet wines permitted to use DAC designation from 2020
• Beerenauslese and TBA are classified as Neusiedlersee DAC Reserve; the sub-designation 'Seewinkel' applies to nobly sweet Reserve wines from Apetlon, Illmitz, and Podersdorf

Burgenland's wine towns cluster around Lake Neusiedl, offering easy access to both vineyards and the UNESCO World Heritage landscape of the lake itself. On the northern shore lie Neusiedl am See and Gols, an important center for red Zweigelt; Andau, Frauenkirchen, and Mönchhof sit to the east; while the sweet-wine heartland of Podersdorf, Illmitz, Apetlon, and Pamhagen stretches along the southern and southeastern shores. Many vineyards in the Seewinkel lie within or adjacent to the Neusiedlersee-Seewinkel National Park, the only steppe national park in Central Europe and a UNESCO World Heritage Site with around 20,000 hectares of protected steppe, wetland, and lake habitat. The flat terrain makes the region ideal for cycling, and wine estates throughout the area offer tasting rooms and cellar-door visits. Burgenland's approximately 300 days of annual sunshine make it one of Austria's most attractive wine tourism destinations year-round.

• Key wine towns: Gols and Neusiedl am See (north shore); Andau, Frauenkirchen, Mönchhof (east); Illmitz, Podersdorf, Apetlon, Pamhagen (south and southeast)
• The Neusiedlersee-Seewinkel National Park, a UNESCO World Heritage Site, covers around 20,000 hectares and is the only steppe park in Central Europe
• Flat terrain and extensive cycling paths make the region well suited to vineyard exploration by bicycle
• Lake Neusiedl is a popular holiday destination for Austrians and international visitors, combining wine tourism with water sports and nature watching
