HM Long

Markus Lang from HM Lang winery

When a former Airbus engineer builds what is probably the world's most powerful wooden press, wines emerge that even Willi Bründlmayer finds captivating. The winery HM Lang in Stein an der Donau demonstrates what happens when technical precision meets 80-year-old vines. Markus and Heideline Lang produce their Demeter-certified Rieslings and Grüner Veltliners in a bomb-proof tunnel deep within gneiss. With 100 tonnes of pressing force and days of pressing under open skies, wines of extraordinary density and minerality emerge – at just 11-12.5% alcohol.




More about HM Lang

From Aircraft Engineering to the Legendary Tree Press

Markus Lang's career path could hardly have been more unconventional. For 25 years, the Viennese engineer designed aircraft for Airbus and the US Air Force, before inheriting a neglected vineyard 15 years ago. Rather than relying on conventional winery equipment, the engineer developed a tree press with 100 tonnes of pressing force – so powerful that even Willi Bründlmayer wanted to press his grapes on it. The pressing, which takes several days and happens in the open air, achieves 80% juice yield instead of the usual 68-72%. Together with his wife Heideline, he now manages 2.5 hectares in the vineyard sites Steiner Schreck and Braunsdorfer, where 80 to 100-year-old vines grow. Like the neighbouring Nikolaihof, HM Lang also consistently follows the Demeter philosophy and is considered a pioneer of biodynamic viticulture on the Danube.

Vinification in a Bomb-Proof Tunnel at 9°C

Deep in the gneiss of the mountain lies Lang's extraordinary cellar: a bomb-proof tunnel from the Second World War with constant 9°C temperatures. Here the wines mature for 2-3 years on full lees in wooden barrels, ceramic amphorae and stoneware. Lang harvests not by sugar content, but by pH value: Riesling at pH 2.9, Grüner Veltliner at pH 3.0. The 2.4-metre-high canopy walls and spontaneous fermentation produce wines with only 11-12.5% alcohol, yet with extraordinary minerality. His top wines include the Riesling Hartstein 2022 as well as the Fuchs & Dachs 2021 from the Riede Braunsdorfer.

Poetic Wine Names with Technical Precision

Lang's wine names tell stories: "Fuchs & Dachs" honours the animals in the vineyard, whilst "This is not a love song" 2021 stands for the Riesling fermented in stoneware amphorae. The name "Kalt und Klar" aptly describes the water of the nearby Danube – and the character of these unfiltered wines. "Dritter Akt" designates the only Grüner Veltliner that still matures entirely in large wooden barrels. With only 12,000 bottles annually and minimal sulphur, wines of extraordinary precision and ageing potential are created. The combination of engineering precision and biodynamic philosophy makes HM Lang one of the most exciting producers in the Kremstal.
