Is there any institution that can identify the authenticity of foreign wine? I've looked everywhere, but I can't find it.

The International Alliance Against Counterfeiting Spirits (AACS) is a global certification body legally authorized by eight foreign wine manufacturers. Is a non-profit organization, which comprehensively represents eight foreign wine manufacturers to deal with intellectual property issues such as product counterfeiting around the world, and its purpose is to share any worldwide problems with its members.
