The California Court of Appeal has ruled in favour of the Napa Valley Vintners, thus ensuring that any wine that carries the word Napa' on the label contains wine made from at least 75% Napa grapes.
This ruling is the latest judgement in a long-running battle with the Bronco Wine Company (famous for producing 'Two-Buck Chuck'), which argued that its brand, Napa Ridge, was exempt from the rule as it was established before 1986, when the regulation came into force.
Kathleen Sullivan, a lawyer representing the Napa Valley Vintners, said: We are extremely happy that the brand name can now be protected against fake Napa wine.'
Bronco said it may appeal to the California Supreme Court.
