Langenlois and Heiligenstein: Austria's Premier Riesling Terroir

Langenlois was first mentioned by name in 1081, with its name traceable to the Liubisa stream, meaning 'the lovely one'. Market rights were granted in 1310 and town status in 1925. The Heiligenstein vineyard itself was first mentioned in a monastic directory in 1280 under the name 'Hellenstein,' a reference to the hellish sun that beats down on the south-facing slope. Approximately 150 years ago, Heiligenstein was one of only two Austrian vineyards sold with the vineyard name on the label, making it a pioneering example of single-vineyard identity. Schloss Gobelsburg's wine production dates to 1171, the estate passing to the Cistercian monks of Zwettl Abbey in 1740. The Kamptal wine region was formally named in 1993, formerly known as Kamptal-Donauland, before receiving DAC status in 2009.

• Langenlois documented from 1081 as 'Liubisa'; market rights 1310; town status 1925; Austria's largest wine-producing town
• Heiligenstein first recorded in 1280 as 'Hellenstein' in a monastic directory, referring to the intense solar radiation of its south-facing slope
• Schloss Gobelsburg wine production dates to 1171, making it the oldest winery in the Danube region; monks of Zwettl Abbey have owned the estate since 1740
• Kamptal region name formalized in 1993 (formerly Kamptal-Donauland); DAC designation granted from vintage 2008, regulated from 2009

Heiligenstein is a steep, terrassed, south-southwest facing slope of approximately 43 hectares, forming a shell-shaped basin open to the south, on the 360-meter-high southern Manhartsberg ridge near the village of Zöbing. The soil is a unique geological island within Europe, dating to the Permian period some 250 to 270 million years ago, comprising desert sandstone with volcanic and carboniferous conglomerates. Despite 'heilig' meaning 'holy' in German, the name derives from the hellish intensity of the sun, which creates a hot and dry microclimate on the terraced slope. Kamptal draws climate influences from both the warm Pannonian Plain to the east and the cooler forests of the Waldviertel to the northwest, producing marked diurnal temperature variation that preserves acidity while enabling full phenolic ripeness.

• Permian desert sandstone foundation approximately 250 to 270 million years old, with volcanic inclusions and carbonized remains of primeval vegetation; a unique geological island in Europe
• 360-meter peak on the southern Manhartsberg; only the south-facing slope is planted to vines; steep terraces prevent permanent loess accumulation, ideal for Riesling
• Name derives from the 'hellish sun' creating a hot, dry microclimate; between vine parcels, protected dry grassland hosts Mediterranean flora and fauna found nowhere else this far north
• Diurnal climate: warm Pannonian winds drive daytime ripening; cool Waldviertel airstreams flow through the Kamp Valley at night, preserving freshness and aromatic complexity

Heiligenstein's steep, rocky terraces are planted exclusively to Riesling, whose preference for poor, well-drained soils makes it the ideal match for the thin Permian sandstone. The mountain's southern slope, with its steep terraces resistant to loess accumulation, yields wines with exceptional minerality, vivid acidity, and considerable aging potential. Young Heiligenstein Rieslings display citrus purity, stony minerality, and saline tension; with age, they develop honeyed complexity and tertiary depth, remaining structured and precise for decades. Kamptal DAC rules require 100% varietal purity for single-vineyard wines; minimum alcohol is 12.5% for municipality-and-vineyard-designated wines, rising to 13% for Reserve expressions.

• Riesling is the sole variety on Heiligenstein's primary-rock terraces; no Grüner Veltliner is planted on the rocky southern slope
• Kamptal DAC single-vineyard wines: 100% Riesling or Grüner Veltliner, minimum 12.5% ABV; Reserve: minimum 13% ABV; both must be dry in style
• Young wines show citrus, stone fruit, and saline minerality driven by Permian sandstone; aged examples develop petrol, honey, and tertiary complexity while retaining structure
• Bründlmayer restricts yields to 3,500 to 4,000 liters per hectare for its classic Heiligenstein bottling; Alte Reben old vines planted from 1923 average over 65 years of age

Weingut Bründlmayer in Langenlois, whose family history dates to 1581 and has been led by Willi Bründlmayer since 1980, farms 90 hectares of certified organic vineyards. The family owns 12 hectares right in the center of Heiligenstein, with 10.5 hectares planted to Riesling. Schloss Gobelsburg, the oldest winery in the Danube region with wine production dating to 1171, is managed by Michael Moosbrugger since 1996 and farms 39 hectares including two south-facing parcels in Heiligenstein totaling 3.5 hectares. Weingut Hirsch in Kammern farms its Heiligenstein holdings biodynamically and is certified by Respekt-BIODYN. Other respected Heiligenstein producers include Jurtschitsch, Hiedler, Allram, Loimer, and Eichinger, with the vineyard divided among approximately 50 owners in total.

• Bründlmayer: 90 ha certified organic; family history to 1581; 12 ha in Heiligenstein center (10.5 ha Riesling); Alte Reben old vines date to 1923
• Schloss Gobelsburg: oldest winery in the Danube region (wine production since 1171); owned by Cistercian monks of Zwettl since 1740; Michael Moosbrugger has managed since 1996
• Hirsch: farms Heiligenstein biodynamically (Respekt-BIODYN certified); pioneered screwcap closures on top single-vineyard wines from 2003
• Heiligenstein has approximately 50 owners in total; nearly every significant Kamptal estate has at least a small parcel, reflecting the vineyard's historic prestige

Since 2009 (vintage 2008), Kamptal bears legal DAC designation status for wines made from Grüner Veltliner or Riesling. The regional name has existed since 1993, replacing the former Kamptal-Donauland designation. Single-vineyard wines with municipality and vineyard designation require a minimum of 12.5% alcohol; Reserve wines require a minimum of 13%. Austria's Wine Law Collective Decree 2023 established the legal basis for an official nationwide vineyard classification system with two tiers: Erste Lage (Premier Cru) and Große Lage (Grand Cru). A site must hold Erste Lage status for at least five years before applying for Große Lage. The first official Erste Lage classifications are not expected before 2025, and Große Lage designations not before 2030. Starting from the 2025 vintage, all Kamptal DAC wines must be produced from certified organic or sustainably farmed grapes.

• Kamptal DAC from 2009 (vintage 2008): 100% Grüner Veltliner or Riesling; single-vineyard minimum 12.5% ABV; Reserve minimum 13% ABV; both dry in style
• Austria's Wine Law Collective Decree 2023: legal basis for Erste Lage (Premier Cru) and Große Lage (Grand Cru); first official Erste Lage classifications expected no earlier than 2025
• Große Lage requires a site to have held Erste Lage status for at least five years; applications go from Regional Wine Committee to National Wine Committee with detailed classification documents
• From the 2025 vintage, all Kamptal DAC wines must use grapes from certified organic or sustainable (Nachhaltig Austria) production

Langenlois is Austria's largest wine-producing town, anchoring the Kamptal wine region along the Kamp River around 70 kilometers northwest of Vienna. The LOISIUM Wine Center, designed by American architect Steven Holl and opened in 2003, connects visitors to a labyrinth of stone cellars approximately 900 years old that run beneath the town; the adjoining spa hotel opened in November 2005. The municipality hosts a variety of wine events throughout the year, including Kellergassenfeste, the Kamp Valley Wine Spring, Tour de Vin, and the Wine Harvest Weeks. The Zöbinger Kellergasse wine cellar lane and the Sauberg in Langenlois provide informal tasting opportunities in a relaxed, family atmosphere. Langenlois sits approximately ten minutes from Krems and provides easy access to the UNESCO World Heritage Site of Wachau.
