The German drink multinational was founded in 1846 by Hubert Underberg I (1817-1891) and his wife on the day of their wedding in Rheinberg (North Rhine-Westphalia) and is still family-owned. It is run in the fourth and fifth generation by Emil Underberg, Christiane Underberg and Hubertine Underberg-Ruder. The best-known product is the eponymous Magenbitter, which was registered in 1896 in the German trademark register. This world-famous herbal liqueur has become synonymous with bitter notes and is still produced today according to a secret recipe with various herbs from 43 countries with 44% vol alcohol content. To this day, the company advertises with the motto "SEMPER IDEM" (always consistent quality and impact) created by the founder. Only three of Underberg's twelve children learned the valuable secret. Allegedly, there were no written records, but the recipe was only passed on orally. After the death of the founder kept the secret widow and daughter, only two other persons (clergymen) knew about the recipe.
