Up until a specific time of the year, typically set by local habits, the “right of banvin” allowed the lord to sell his own wine before that of his vassals (the time during which the sale of wines other than those belonging to the lord were banned varied greatly from one fief to another).

The oven, mill, and press belonged to the lord, who allowed his subjects to use them in exchange for the payment of a tax. When local production was too large in volume, he handled exporting the wines and finding outlets. He gave himself this banvin right, which dates from the Carolingian era, in return for this “over-production” service.

The public announcement permitting the sale of the wine was also known as “banvin.”
