To delve even deeper with Cognac and Armagnac, they live about 180 miles apart, so they're practically neighbours. Cognac is mostly made from one sort of grape, while Armagnac loves variety. The most interesting difference is their PR: Armagnac is one of the oldest Spirits on the planet and it was rarely exported. Cognac, on the other hand, was the export blockbuster with good marketing. It even had Napoleon III as its poster boy, who made sure Cognac was sold in every medieval supermarket.
