I love 5100. I love all of McClelland's Virginias. And their English, Balkan, VaPer....anything flake. The ketchup thing evades me, though. I get the spice. Mike McNeil says that it's the smell of fermenting tobacco. That might be some of it, but McClelland blends have a unique aroma that to my limited knowledge has to be a topping. Clove? What else? That could be misconstrued as ketchup, but as Styler says, no tomato aroma at all. I don't even get an acetic acid smell and I spent years smelling that stuff in photo stop bath. Either way, I've socked away 5# bags of most of their flakes and 5100. Time is going to be a wonderful thing for these unique blends.
