Wine experts in London and California are preparing to hold a blind tasting to decide who makes the best wine: France or the United States.

In recent years, new world wines have overtaken global sales of French wine.

The tasting is to take place on neutral territory in London at the Berry Brothers & Rudd wine shop in St James's Street - one of the UK's oldest wine and spirits merchants.

The US tasting is being held at Copia, the US centre for wine, food & the arts, in the Napa Valley, California, a region famous for its wine production.

Back in 1976, in a contest called Judgment of Paris, nine French experts agreed that the Californian wines they had blind-tasted were better than the French.

The rematch includes all the original red wines tasted in 1976, to see how they have aged, as well as newer vintages from both nations.
