Edward Hyams was among the first to reintroduce vines as wine growing
plants to UK. http://www.molash.com/archive/hyams.htm He grew several
here and in Kent before he moved and they were not a total success.
Otoh, Sharpham Vineyard on the banks of the Dart, about 30 minutes drive
from here on a busy day, produces delicious wine. We do have commercial
vineyards but not in the thousands and thousands of bottles that can be
produced in e.g. Bordeaux.
