On June 10, 1991, a group of winegrowers gathered at Kloster Und in Krems an der Donau for the founding general assembly of the "Österreichische Traditionsweingüter" (ÖTW), an association that would go on to reshape how Austrian wine sites are understood and communicated.
The idea, however, had taken shape months earlier. At a meeting on January 9, 1991, at the Ursin Haus in Langenlois, a handful of prominent producers from the Kamptal and Kremstal regions sketched out the foundational principles of what would become the ÖTW — including an early outline for a vineyard classification system.
Among the founding figures were some of the most recognizable names in Austrian wine: Willi Bründlmayer, Ludwig Hiedler, and Karl Jurtschitsch, all from Langenlois; Peter Dolle from Straß im Straßertale; Gerald Malat from Furth bei Göttweig; Josef Mantler from Gedersdorf near Krems; Erich Salomon from Stein an der Donau; and Kurt Körbler, then head of the municipal winery of Krems. Their shared conviction was that Austria's finest vineyard sites deserved formal recognition, in the spirit of classification systems long established elsewhere in Europe.
Growth Beyond Kamptal and Kremstal
When the ÖTW formally launched in June 1991, it counted 18 member wineries, all based in Kamptal and Kremstal. The name "Österreichische Traditionsweingüter" — Austrian Traditional Wine Estates — was deliberately chosen to leave room for growth beyond these two regions.
That expansion came gradually. The first decade saw relatively little change in membership, but by the early 2000s wineries from the Traisental and Wagram regions began to join. Membership numbers reflect this steady trajectory: from 18 wineries in 1991 to 24 by 2001, and 30 by 2010. By 2023, the ÖTW had grown to 78 member estates.
The organization's structure evolved alongside its membership. In 2018, the ÖTW established an umbrella body, the "Bundesverband Österreichische Traditionsweingüter," together with a regional association called ÖTW.Donau, encompassing four sub-regional groups: ÖTW.Kamptal, ÖTW.Kremstal, ÖTW.Traisental, and ÖTW.Wagram. Two further regional associations, ÖTW.Wien and ÖTW.Carnuntum, joined the fold soon after. The Thermenregion became part of the ÖTW in 2021, followed by the Weinviertel in 2024 — extending the association's reach across a significant swath of Austria's wine-producing landscape.
Today, the Bundesverband Österreichische Traditionsweingüter is headquartered at Kloster Und in Krems an der Donau, the same site where the association was founded more than three decades ago. Michael Tischler-Zimmermann has served as Managing Director since 2024.
The Long Road to a Legal Classification
Classifying vineyard sites has been the ÖTW's defining ambition since its earliest days, and the path to achieving that goal was far from straightforward. In August 1991, shortly after its founding, the association defined its first classification criteria and began evaluating specific sites. Two tiers were introduced: "Klassifizierte Lage," open to white, red, and rosé wines, and "Erste Lage," reserved exclusively for white wines. A further tier, "Große Erste Lage," was envisioned for later introduction.
This early system hit a legal obstacle almost immediately. Austrian labeling law prevented the ÖTW from using these classification terms from the 1994 vintage onward. Rather than abandon its mission, the association redirected its energy toward other activities — most notably organizing joint events — while continuing to work toward its long-term goal of having vineyard classification formally recognized within Austrian wine law.
That goal was finally realized in 2010, when, starting with the 2009 vintage, the ÖTW succeeded in bringing its classification system into alignment with wine law through the newly introduced "ÖTW Erste Lage" designation. Since then, qualifying wines have carried the "1ÖTW" logo on their labels and bottle necks. A further tier, "ÖTW Große Lage," is planned for future rollout, continuing the association's original three-tier vision.
What Goes Into a Classification
The ÖTW's classification isn't based on reputation alone. In 2010, the association established a formal set of relevance criteria used to evaluate and classify vineyard sites, grouped into three categories:
- Content Relevance Criteria — factors such as a site's historical significance and the geological and locational homogeneity of the vineyard.
- Economic Relevance Criteria — including the average market price achieved by wines from a given site.
- Qualitative Relevance Criteria — such as how wines from the site perform in expert evaluations, along with measures of consistency over time.
Classification is paired with strict production standards. All ÖTW member wineries must hold certification under the Austrian sustainability seal "Nachhaltig Austria," the EU's organic "Biological Grape Production" seal, or an equivalent standard. Herbicides and insecticides are banned outright in ÖTW vineyards. For sites labeled 1ÖTW specifically, yields are capped at 60 hectoliters per hectare, grapes must be hand-harvested, and the resulting must cannot be concentrated.
Aging requirements round out the standard: white wines from ÖTW Erste Lagen may not be released before September of the year following harvest, while red wines from these sites must wait until September of the second year after harvest before reaching the market.
A Model Built on Patience
The ÖTW's story is, in many ways, a story of persistence. A concept sketched out over a single meeting in January 1991 survived a legal setback that stripped the association of its own terminology for over a decade and a half — yet it never abandoned its founding ambition. What began as an initiative among a small circle of Kamptal and Kremstal producers has grown into a nationwide framework spanning nine regions and dozens of estates, with a rigorous, multi-layered classification system that finally found its footing in Austrian law in 2010.
For a wine culture historically less associated with formal site hierarchies than Burgundy or the Mosel, the ÖTW represents a deliberate, decades-long effort to give Austria's best vineyards the recognition — and the legal standing — that its founders believed they deserved.
