So look at the label. “Ireland Beer”. Green background. Some Celtic castles that look suspiciously like the Dublin coat of arms. “Dublin Export”.
But, I don’t think this beer has anywhere near Ireland, let alone Dublin. It’s made by “Corbelli Wines”, the Dublin coat of arms is normally portrayed on a blue background, and there is no indication that this beer is specifically made in Ireland. Yep, I think it is made in the EU, but Corbelli comes from the West Midlands! which is even more confusing.
One to avoid. Dubious origins and crap beer.

I think this is quite a nice beer. Good flavour, reasonably priced, and it comes in 500ml cans – winning:)
