Imagine a time before motor vehicles when the pace of life was slow and the work was hard. In those days moving produce out of Languedoc was difficult and involved a long sea voyage around Spain and Portugal or along rough, rutted roads with a horse and cart. Wine was moved from wineries in barrels, on carts from villages to towns but to move it any further caused it to spoil with the jostling of the cart.
In the 17th century the market for wine was where the population was growing, mainly in the north, in larger towns such as Paris but also the lucrative export markets including Holland and the British Isles. In the parts of France that had navigable rivers or where towns were close to the Atlantic such as Bordeaux, it was reasonably easy to move wine north. For Languedoc the nearest Atlantic port was Bordeaux but due to a protectionist law known as the Bordeaux Privilege hardly any Languedoc wine left the French shore from Bordeaux. The only choice left to the folk of Languedoc was a long sea voyage around Spain and Portugal which could also spoil the wine.
