Wine expert Oz Clarke and comedian Hugh Dennis (Oz has obviously worn James May down beyond repair) embark on a challenge to set up the UK's most patriotic drinking establishment. Their journey takes them right across the UK (and Ireland), looking for the best drinks from their homeland to stock their cellar. But there is a twist - the duo will be in competition, running a bar each inside the pub. Their search begins with a tour of England's south. They discover hidden gems, from the award-winning sparkling wines of Sussex to the offal- and jellyfish-flavoured beers of Cornwall, and from alcoholic ginger beer to sweet farmhouse cider. Following a revel in a Cornish pub, Oz concocts some old-fashioned hangover cures, with upsetting results.
