England used to be noted for Claret. Perhaps it can be again.
During the Medieval Warm Period, the UK became more respected for wine than France. Looks like we might be repeating that in the Modern Warm Period. The political class tells us to fear global warming. But people like you and me who know history know that the Modern Warm Period is just a repeat of prior warm periods.
Yes, but claret was not grown in England, despite it being one of the most popular drinks there in the Middle Ages - for those who could afford it.
It was from Aquitaine, i.e. Southwest France, which was a fief of the English King for centuries. Thus, while not being techniclly part of the Kingdom of England, both territories had strong economic ties to each other.
English wines were considered very good, too, during the Medieval Climate Optimum, but they were mostly white, as far as I know.
White grapes, actually, can abide slightly cooler climates than red ones, and they can even benefit (when growing-conditions are right) from the weather not being too hot.
