On June 17, 1846, Hubert Underberg founded the company H. Underberg-Albrecht in Rheinberg in Germany, starting the manufacture and sale of Underberg, a specialty made with aromatic herbs. In 1884, Hubert Underberg began to export his product to Brazil. In 1932, the grandson of the founder, Dr. Paul Underberg moved to Brazil and began to manufacture the "Underberg do Brasil". This product made in the country with Brazilian herbs has become, over the decades, an original Brazilian specialty and henceforth bears the name Brasilberg from the house "Underberg do Brasil". Underberg is based on a secret and proprietary recipe, guarded by the Underberg family since the company was founded by Hubert Underberg-Albrecht in 1846. The herbs are distilled using a process called semper idem (or "always the same"). The extracts are then matured for months in barrels made of Slovenian oak.
