Although the Treaty of Versailles (1919) already forbade use of the name “Cognac” from being used for products produced outside of the French Cognac region, Dutch Brandy (including Plantinga Cognac) continued to be sold under the Cognac name until the 1960s. The packaging (including stars) was clearly derived from Cognac packaging. Pressure from the French government led to a law that then definitely no longer allowed for the name “Cognac” to be used. It was ratified by the Dutch Supreme Court in a Trade Treaty with France on 1 June 1956.
