Ferrero Duplo Chocolate Bar

Duplo is a renowned chocolate bar known for its hazelnut cream and crispy wafer, famously marketed as 'the longest praline in the world.' The brand was originally launched in Germany in 1964 by the Italian company Ferrero. It has since become a staple in the European confectionery market, particularly within the DACH region (Germany, Austria, and Switzerland).

Manufacturing for Duplo is primarily centered in Stadtallendorf, Germany, which serves as a major hub for Ferrero's northern and central European supply. Additional production occurs in Italy to meet demand in other markets. The brand is managed by Ferrero Deutschland GmbH for the German market.

Ferrero remains a private, family-owned multinational giant. While the company was founded in Alba, Italy, its ultimate administrative headquarters are now based in Luxembourg. The Ferrero family continues to maintain operational and strategic control over its vast portfolio of global brands, including Nutella and Kinder.
