Samuel Smith's Old Tadcaster.
Geez, how can I forget Anchor Porter?
I think most porters are named as such. So if it doesn't say "porter" on the menu, it's probably not.
I'm kinda surprised at the lack of popularity of this style, at least locally. I can't think of a bar that has one on tap.
Making the world a bitter place, one IBU at a time.
