I've been working on approximating Sam Smith's Taddy Porter for the past few months and have had a difficult time nailing the yeast profile. After some searching, I noticed that Wyeast has a seasonal strain called West Yorkshire (or something to that effect) that is possibly the Sam Smith's strain. Unfortunately, it's not available right now. Are there other yeasts that will get me in the ballpark? Maybe Wyeast Ringwood? London ESB? Whitbread? At this point, I'm not terribly interested in making a perfect clone of the Taddy Porter. I'd be happy with something relatively close. Suggestions?
