Castel, the French wine group, has signed a deal to acquire the Selles wine merchant, which operates in the Rhone Valley and Beaujolais regions.

Family-owned Selles, founded in 1975, specialises in appellation controlee wines, said Castel today (9 July). Financial details of the detail were not disclosed.

"Selles activity is complementary to Castel's as it will increase the group's development in own-label and private brands in France and abroad," said Castel, which is one of the world's largest wine merchants.

The move for Selles comes after Castel bought own-label wine specialist Oenoalliance in Bordeaux in 2008.

Selles has two bottling facilities in the southern French Rhone area.
