Dortmunder Export Emerges as a Distinct Beer Style

During the 1870s, Dortmunder Export emerged as a distinct pale lager tradition in Dortmund, an industrial brewing center in Germany’s Ruhr region. Bottom-fermented brewing had been introduced to the city by Heinrich Wenker and Wilhelm Overbeck around 1843, but Dortmund’s breweries later developed a stronger pale lager in response to the growing popularity of pilsner-type beers. The designation “Export” reflected a beer brewed to a comparatively high original gravity and suitable for distribution beyond its local market. Dortmund’s mineral-rich water contained substantial levels of sulfates, carbonates, and chlorides. Combined with pale malt, bottom-fermenting yeast, and firm hopping, this water contributed to a beer that was fuller and more mineral-driven than Czech pilsner while generally more bitter and attenuated than Munich Helles. Dortmunder Export became closely associated with the city’s expanding coal, steel, and brewing industries and grew into one of Germany’s most popular beer types after the Second World War.
