Yes but also the soil is very similar apparently

Well, as it happens, the soils in many areas of Kent, Sussex and Surrey, have an equally high chalk content as the soils of the hallowed growing areas of Champagne, and that’s because this area is part of the same Paris Basin that developed thick chalk layers formed by plankton fossils between 60 and 100 million years ago.

Not only that, but the climate in the south east of England is comparable to that of Champagne 50 years ago, whereas the one degree rise in temperature in north east France has resulted in an alarming proportion of dried out grapes due to excess heat.
