Henry Jeffreys's book, Vines in a Cold Climate, is an essential and extremely engaging history of the development of English wine since the 1970s. He interviews many characters and charts the change from amateur DIY winemakers to the professionalism of the industry in the 1990s to the investment from wealthy entrepreneurs in the 2000s onwards. I talk to him about how English wine, sparkling in particular, has become such a talking point, referencing the climate, the place, and the people behind the rise of the industry.
