Interesting to get any input from any Irish in here on the implementation of this. I find it bizarre that the increase cost goes into the pockets of the seller. I would have thought the government would have used used some sort of mechanism of collecting the money and using it elsewhere.
We've had it in Scotland for a few years now. It is bizarre but in Scotland at least it was done because the Scottish government doesn't have the power to raise alcohol duties so this was a workaround.
It has basically killed the market for cheap ciders like White Lightning. There have been some limited studies showing reduction in drinking, at least up until Covid, though I don't think there has been anything conclusive to show MUP was the cause.
For me personally, and for the vast majority of people it hasn't made much difference at all - everything I was drinking was already above the minimum price anyway.
