Climate change is transforming wine production around the world. New wine-growing regions are emerging, where the conditions have never been better; while for many traditional producers, drought and rising temperatures are causing a crisis. How is the changing climate impacting the taste and origin of wine, and who are the winners and losers?

Presenter Sophie Eastaugh heads to the Crouch Valley in Essex, England, to find out why the area’s becoming a hotspot for boutique wine. And she travels to Penedes in Catalonia, where one of Spain’s oldest family wine companies, Familia Torres, are battling a four-year drought. How can traditional wine growers adapt to the challenge of a warming world?
