A bomb blast has damaged a winery in the Languedoc region of France, according to Decanter. The bomb - a stick of dynamite - was detonated at La Baume winery last Monday, Decanter said, in an apparent protest against the power of larger companies.

No-one was injured in the blast but the barrel cellar and roof suffered some damage.

Decanter said that it is alleged that a group called Comite Regional d'Action Viticole (CRAV) took responsibility for the attack, in the form of a scrawled message on a wall at the winery.

Tim North, UK director of Les Grands Chais de France, which owns La Baume, blamed "a small minority of extremists" who had "not moved with the times" and had "strong feelings against global companies."

"Many people in that part of France understand the world is changing and people are no longer content to drink cheap vin de pays," North told Decanter. "But there are others who have not moved with the times and they have strong feelings against global companies."

Les Grands Chais de France is the country's biggest wine exporter.
