Bahlsen Choco Leibniz Milk

Bahlsen Choco Leibniz is a signature butter biscuit set in a thick tablet of milk chocolate, first introduced by the German family-owned company Bahlsen. The brand has a history dating back to 1889 when Hermann Bahlsen founded the 'Hannoversche Cakesfabrik' in Hanover, Germany. The name 'Leibniz' was chosen in 1891 as an homage to the philosopher Gottfried Wilhelm Leibniz, continuing a tradition of named baked goods common at the time.

Today, the product is primarily manufactured at Bahlsen's production sites in Germany (notably Barsinghausen and Varel) and Poland (Skawina and Jawornik). The brand remains a family-owned enterprise, headquartered in Hanover, Germany. It is officially managed by the fourth generation of the Bahlsen family under the parent company Bahlsen GmbH & Co. KG.

The packaging often features the 'TET' symbol, inspired by an ancient Egyptian hieroglyph meaning 'everlasting,' which was adopted by the founder to signify the long shelf-life and high quality of his biscuits. As of 2026, the company continues to operate as a leading independent player in the global biscuit market, maintaining its heritage as a privately held German entity.
