This map, published by Frenchman Charles Joseph Minard in 1864, represents an approximation of French wine exports in 1864.
Minard was a pioneer in cartography aimed at representing data.. With the data available at the time, which was highly unreliable and fragmented, Minard attempted to represent French wine exports to other parts of the world. To do this, he used red lines of varying thickness depending on the volume of wine exported in each direction. In this way, it is possible to intuitively see how the largest volume went to Italy and Algeria, then a French colony, followed by the United Kingdom, Germany, Argentina, Brazil, the United States and Uruguay.
Following the export routes to the Caribbean, Africa and South Asia, a quick correlation can be established with the French colonies in different parts of the world, as they all received a significant volume of wine from the metropolis.
French wine has always enjoyed a great reputation, although it was from the 18th century onwards that improvements in vine cultivation and wine production significantly increased the number of litres produced. This meant that during the 19th century, large quantities could be exported to other countries around the world, as shown on this map.
