In the fourth show, James Purefoy and Matthew Goode find themselves in stunning Burgundy on the hunt to each find a wine to match the main course in their epic six-course lunch. With Coq aux Vin on the menu, it's the only place to be. They visit the historic Chateau du Clos du Vougeot and the Confrerie du Chevaliers du Tastevin – the knights of the Order of Winetasters. They learn about the history of the chateau and Burgundy but before they can choose a wine, have to sit an exam. Can they learn their wines as well as their lines? With their wines chosen they head back to their villa for the judgement of Jancis Robinson, the world's most influential wine critic. Meanwhile Joe Fattorini is competing in the Medoc Marathon with Jamie Ramsay, adventure runner. This is a full marathon where every mile there is a chateau offering a sample of their latest vintage to all the competitors. With the mercury hitting 30 degrees C and Joe in fancy dress, things don't work out quite as Joe hoped. Amelia Singer joins Joe in Canada, to find out if their wines can really hold their own against more established wine regions. And back in London, Matthew Rhys is at Berry Brothers & Rudd in London's St James's looking at historic and modern gadgets. (thetvdb.com)
