I've not read his new book, Future Makers: Australian Wines For The 21St Century, but I did catch his interview on the ABC's Bush Telegraph program on Oct 10th. If you missed it, catch up with it here. The MP3 podcast can be found more directly here. There's some interesting stuff on his views about climate change and wine.
Not the first time I've heard about that either, with large French wine companies buying up South England land to prep for climate change. Pity they haven't heard that one side effect might be to make England cooler due to the gulf stream changing or even stopping according to some.
