Video and photos posted on social media showed large groups of people gathering outside Hennessy's headquarters in Cognac, some wearing jackets showing the logos of CGT and Force Ouvriere, another union.
Hennessy management told employee representatives on Tuesday that it planned to first send a sample shipment of 1,000 litres of its very special old pale (VSOP) cognac to China to test the product's stability, added Lablanche, who said he was briefed by employees after the meeting.
The test shipment is due to take place on Dec. 15, local newspaper Charente Libre reported.
If the test is successful, the group will relocate the whole VSOP bottling line to China, added Lablanche, to handle 600,000 cases of the brandy, or all of its 2025 China sales.
Remy Cointreau, a smaller cognac maker, has said it will
raise cognac prices in China to help mitigate the impact of tariffs imposed by Beijing, and could also cut costs in areas such as manufacturing and advertising spending.
It has no plans to relocate its bottling line, a company spokesperson said.
The Bureau National Interprofessionnel du Cognac, an industry lobby group, has repeatedly urged the French government to negotiate a solution to protect the cognac industry.
"Some houses may be forced to explore all options that would enable them to maintain the presence of the appellation on the Chinese market," it said in a statement on Monday.
