Fake bottles of Australia's best-selling Jacob's Creek wine have flooded the UK market, but were discovered because of a typo on the label.

Hundreds of bottles of imitation Jacob's Creek, which have made their way into bottle shops across the country, have already been seized.

The wine appears identical to the real thing apart from a tell-tale misspelling of Australia on the label - and the apparently horrible taste.

The fakes are believed to have come from China.

Trading standards officials are warning consumers to look for the label error when buying a bottle of one of the UK's favourite wines.

Pernod Ricard United Kingdom, owner of Jacob's Creek, has launched an investigation.
