The worst smoke I recall off hand was from a pouch of Middleton Cherry blend. After I bought it, it was obvious that it had been sitting on the shelf for a very long time. Quite dried out. (It was bought from a smoke shop that specializes in cigarettes and had only a few pouches of OTC pipe tobacco.) - - I'm not a big aro smoker and maybe a fresh pouch is better. But, this had a metallic taste with no cherry at all. I might have gone ten puffs before calling it quits.
