Duplo Chocolate Bar

Duplo is a popular hazelnut-filled wafer chocolate bar originally launched in Germany in 1964. Marketing itself as 'the longest pralines in the world,' it has become one of the best-selling chocolate snacks in the DACH region (Germany, Austria, Switzerland).

The brand belongs to the Ferrero Group, an Italian global confectionery giant founded by Pietro Ferrero. While the brand has its roots in German market specialization, it is now an international household name. Production is primarily concentrated in Germany (Stadtallendorf) to serve the central European market, though Ferrero utilizes its global network of facilities for distribution and subsidiary manufacturing.
