The beer style became well-known internationally, in particular due to the Dreher brewery's restaurant and beer hall at the International Exposition of 1867 in Paris, and started getting copied by many of the US-American lager breweries founded by German immigrants. The first amber-colored Oktoberfest-Märzen brewed by Franziskaner-Leistbräu in 1872 was also a Vienna-style beer brewed to a higher strength.
