 Winemaking continued at least down to the time of the Normans, with over 40 vineyards in England mentioned in the Domesday Book, although much of what was being produced was for making communion wine for the Eucharist.From the Middle Ages, the English market was the main customer of clarets from Bordeaux, France, helped by the Plantagenet kingdom, which included England and large provinces in France.In the 18th century, the Methuen Treaty of 1703 imposed high duties on French wine.
