Why is the French wine industry struggling?

The region of Bordeaux in the south-west of France is perhaps the most famous wine-producing area in the world. But it’s struggling. While the prestigious, most expensive wines – Saint-Émilions, Pomerols and Margaux are selling well, others are not. For the producers of the 850 million bottles of the region's famous red wine, it’s a difficult time due to a major decline in consumption. We look at the reasons for this, the impact it’s having, and what winemakers are doing to help protect their livelihoods. Presenter: John Laurenson (Image: A glass of red wine. Credit: Getty Images)
