No holder of a Certificate of Approval shall offer to a wholesaler any brand that would by nature of its label be handled by a single licensee or a restricted group of licensees. All such brands approved for sale must be available to all retail licensees for resale to the consuming public. In instances wherein the affected wholesaler has a brand on allocation, all retail licensees shall be allowed, on a percentage basis, to purchase the allocated brand.
