Haunted Bookshop was one of the first few tobaccos I smoked. And the first one I really "got". I think it's because I was/ am coming to pipes from cigarettes. When pushed, HB gets quite cigarette-ish. When slowed down, it's much different. That bit of cigarette helped me learn to smoke, I think.
And with a few years in a jar, most of the rough edges are gone and I've found the flavors mature wonderfully. Well worth the space in the cellar.
