Bahlsen Leibniz Keks biscuit

The Leibniz-Keks is a classic butter biscuit that has become a staple of German confectionery. Originally introduced in 1891 by Hermann Bahlsen, the biscuit was named after the philosopher Gottfried Wilhelm Leibniz. It is characterized by its signature design of 52 teeth around the edge and the 'LEIBNIZ' name embossed in the center.

Today, the brand remains a family-owned enterprise through the Bahlsen company. While the heart of production remains in Germany, particularly at sites like Barsinghausen near Hanover, the company has expanded its manufacturing footprint to include facilities in Poland to serve international markets. The ultimate ownership continues to reside with the Bahlsen family, maintaining a long-standing tradition of German baking excellence and global distribution.
