It's the 1970s and Australian wine is a joke "not for drinking, as Monty Python put it, but for "laying down and avoiding". The idea that a wine made 'Down Under' could ever challenge the august products of Burgundy or Tuscany has wine buffs and snobby sommeliers sniggering into their tasting spoons. In a story-line remarkably similar to that of Napa Valley, 40 years later Australian winemaking is leading the world. London merchants sell more wine from Australia than any other country, while the chastened French wine industry reluctantly takes note of how modern winemaking and wine marketing is really done. Chateau Chunder is both a social history of wine and wine drinking and an in-depth examination of how a small group of enterprising Australian wine makers took on the world and won. With humour and insight, the documentary features winemakers, marketers, merchants, critics and drinkers including Bruce Tyrrell (Tyrell's Wines), Robert Hill Smith (Yalumba), James Halliday and Max Allen (Australian wine critics), Oz Clarke and Jancis Robinson (UK wine critics), and Sir Les Patterson (Cultural Attache to Australia, a comic creation of Barry Humphries).
