Where the first pure lager yeast culture was isolated, an advance that made consistent industrial lager brewing possible worldwide.
Emil Christian Hansen’s work at the Carlsberg Laboratory in the 1880s produced the first single-cell pure culture of lager yeast. Before it, fermentation was a matter of repitching mixed populations and hoping; after it, lager could be brewed reproducibly at scale anywhere.
Carlsberg released the technique without patent restriction, which is a substantial part of why lager spread as fast as it did.
