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.

Thirty years ago English sparkling wine wasn't a thing; twenty years ago it was barely known about; ten years it was little understood; now it's appreciated as one of the best regions for quality bubbles; the next ten years may see England really become established on the world map. To discuss all this more, listen to my interview with Trevor Clough of Digby Fine English - who make some fantastic sparkling wine.
