Guinness is one most highly overrated beers that I have ever had.
I disagree. But I am dark and brooding.
Several years ago, they changed the shape of Guinness bottles. I swear that when they did that, they also changed what was inside. It just didn't taste as good as it used to.
Draft Guinness, in Ireland, is wonderful stuff. Guinness in this country, draft or canned, varies from OK to not very good. Guinness from Nigeria, which is, or was, actually a thing, is foul.
It sounds pretentious, but it is true — draft Guinness, drank in Dublin, or Belfast, is wonderful. Don’t judge it until you have had it there.
