The Autorité de la concurrence, the French competition authority, has provided guidance on inter-branch reserves in the wine sector. They have stated that inter-branch organisations can implement a price tunnel principle, as long as the minimum and maximum price limits are set independently by each contracting party.

This opinion aims to ensure that competition within the wine sector is not distorted by the establishment of inter-branch reserves. By allowing operators to freely determine price limits, the Autorité seeks to maintain a level playing field and prevent anti-competitive practices.
