A Revenue spokeswoman said the beer was seized "following routine profiling aimed at identifying alcohol products that may be diverted onto the market without payment of the tax and duties due".
She said: "Investigations are ongoing. This seizure is part of Revenue’s ongoing operations targeting the supply and sale of illicit alcohol products in the shadow economy.
"If businesses, or members of the public, have any information, they can contact Revenue in confidence on Confidential Phone Number 1800 295 295."
