More than 23 thousand litres of beer has been seized at Dublin Port.
Revenue officers found the alcohol without correct papers in a truck that arrived from Holyhead this morning.
A man in his thirties has been questioned about the haul, believed to be worth more than €100,000.
In a statement, Revene said the contraband beer found "was an attempt to divert alcohol onto the market using fraudulent documents and without payment of the tax due."
"The driver, a Polish man in his 30s was questioned and an investigation is underway with a view to prosecution."
