Due to business steadily improving, the company expanded and went public in 1872, changing its name to "Dortmunder Actien Brauerei" (Dortmund Joint Stock Brewery). In 1879, the company started to export its beer internationally. In 1881, Carl von Linde himself equipped the brewery with one of his refrigeration machines, allowing for a boom of bottom-fermented beer. In 1893, the brewery established a chemical and bacteriological laboratory. Although World War I led to a crash in beer production, the brewery was equipped with its own railway connection in 1917. After the near-total destruction of Dortmund in World War II, the brewery was rebuilt by 1949.
