The appellation has been named after the city of the same name, which is the capital of the Lot department in south-western France. The vineyard area totals around 4.500 hectares, the vineyards are located on both banks of the Lot river, to the north-west of Gaillac. The wine-growing region is one of the oldest and also one of the most famous in France. The Celts, or Gauls as they were known here, produced oak barrels here as early as the 6th century BC. The Romans grew wine here under emperor Domitian (51-96 AD). Wine from Cahors was exported to England in the 13th century, and was held in high esteem there, being known as „black wine”. The man who was later to become pope John XII. (1244–1334) was born here, and a university he founded was in existence for more than 400 years. When the pope was resident in Avignon on the Rhône river, he invited wine-growers from the Cahors region to come to the Rhône, and to plant the predecessor of what was to become Châteauneuf-du-Pape wine. King Francis I. (1494–1547) was so enthusiastic about the reputation of Cahors wines, that he had vines planted at his residence Fontainebleau (city to the south-east of Paris). The orthodox church purchased communion wine from Cahors, and the Russian Zars enjoyed the wines at special court occasions. Because the original was difficult to pronounce, it became known as Kagor, and became a sysnonym for communion wine. The famous Massandra wine estate in the Ukraine, owned by the Czar, produced a dessert wine modelled on Cahors, which is still produced today. In the 19th century, the „black wine of Cahors” built up a legendary reputation. At that time, part of the must was boiled to make it thicker and more syrupy, this also helped to make the wine such a dark colour.
