The humble wine cork, once the main way to stop a bottle of wine, had its market share decimated in the 1990鈥檚 when screw caps were favoured. However, the problem of 'corked' wine has been almost completely solved and cork is recognised as a more sustainable, if slightly less convenient material for wine makers to use.

In this episode we visit the world鈥檚 largest cork producing region in Portugal to find out more about how the cork industry has hit the good times once again. We explore which wines taste better with cork and how supermarkets are cutting down on wine packaging.
