I only drank some Irish beer that had close to 10% alcohol in it. The vast majority of beer has around 5% alcohol, slightly under or slightly over it. That's common knowledge.
I don't know. I've never had it. Even went out of my way to try it a few weeks back but none of the places we went to had it. Even a few with big Stella logos on their building.
I don't know if that means they're hiding in shame or what, but Stella is hard to find. In Belgium...
