Yes, it's extremely strong. Anywhere from 9% alcohol for the North Coast one, to 11% alcohol for the Rogue brew. Definitely a celebration beer.

I think Sammy Smith's Imperial Stout gets distributed all over. (I've seen it in MD, IN, IL and ID). It's worth a try.

I know Bell's out of Kalamazoo makes a fantastic chocolate stout, but I don't know if they have an imperial.
