In 1862 the French government invited industry to take part in the Universal Exhibition in London. Jean-Baptiste Nouvion, the sub-prefect of Philippeville, urged Gaëtan Picon to bring his aperitif Sirop de Picon to the exhibition. But, failing to convince the manufacturer to take part, the sub-prefect stubbornly took it upon himself (without telling Mr. Picon) to ship a case of African Amer to London. The product ended up crowned with a bronze medal in the bitter aperitif category, greatly adding to Gaëtan Picon's eventual fortune.
