Interesting that you consistently got the sourness, too Martin. I'll try a few more bowls. The sample I have is from 2008, Mark so not enough age is probably not the issue. I'll definitely try it in a cob, though. It sure looks and smells amazing in the bag.
So far Old Gowrie is far preferable - loved that one at first puff. Still need to try Hal o' the Wynd.
