Known for: Danish lager and the Carlsberg Laboratory, which isolated pure yeast strains and helped establish the pH scale — discoveries that transformed brewing science worldwide.
History: Founded in 1847 by J.C. Jacobsen outside Copenhagen. The Carlsberg Laboratory, established 1875, is where Emil Chr. Hansen first isolated a single-strain lager yeast in 1883 — a discovery that eliminated batch-to-batch inconsistency and made modern industrial brewing possible. Carlsberg didn't just make beer; it made modern brewing science. Still headquartered in Copenhagen and controlled by the Carlsberg Foundation.
