What’s Ireland got to do with the UK’s alcohol laws? If it’s a racist trope you’re trying to make, you might be happy to know that Ireland consumes virtually the same quantity of alcohol per capita as the UK.
I mentioned Ireland because Ireland is in the EU and uses English officially so I wouldn't be at all surprised if the use of "alcohol-free" in Ireland corresponds to the use of "alkoholfrei" in Germany rather than to the use of "alcohol-free" in the UK, those two apparently being different. It honestly hadn't occurred to me that someone might suspect a racist trope!
It’s an EU wide definition that exists in 27 countries not specific to Ireland. Your comment was unfortunately worded if thats the case as at least two other people picked up on the same remark. Apologies if so.
