An RFID label comprising an RFID circuit and an RFID antenna, and optional secondary security label ensures the authenticity of a beverage contained in a beverage container. The RFID label cannot be removed without destroying the RFID label or rendering it inoperable. A secondary security label may be placed over the closure of the beverage container to provide a secondary measure against tampering as well as a visual indicator of authenticity. It is placed on a portion of the bottle, a portion of the beverage container's closure, and the RFID label. An attempt to remove the secondary security label will also render the RFID label unusable.
