Any product produced or packaged at the host brewer's premises shall be removed from the host brewer's premises within 10 days after the brewing or packaging process is completed. The finished product shall be returned to the tenant brewer's brewery of origin or to a wholesaler licensed pursuant to section 18 or to a license holder outside the commonwealth authorized to import malt beverages designated by the tenant brewer.
