== History == left|thumb|Löwensenf Headquarters in Düsseldorf. On November 1, 1903, Otto Frenzel founded the Erste Lothringische Essig- und Senffabrik (First Lorraine Vinegar and Mustard Factory) in Metz, then a part of the German Empire. In 1920 after the First World war and the return of Metz and Alsace-Lorraine as a whole to France, the company was moved to Düsseldorf and renamed Neue Düsseldorfer Senfindustrie (New Düsseldorf Mustard Company). Also in 1920, the most well known product, Löwensenf Extra, a sharp Dijon-style mustard was introduced. After the death of Otto Frenzel in 1936, his widow, Frieda Frenzel took over management of the company. In 1948, production was started again after disruptions caused by the Second World War. In the mid-1960s, Löwensenf acquired two other Düsseldorf mustard manufacturers, ABB and Radschläger.
