Okay, I've been struggling with this for a long time so finally decided to throw it out there. My favorite pipe tobacco is SG Black XX Twist rope. I've been smoking pipes in earnest for about 2 and a half years and I remember early on thinking I should wait awhile on rope tobacco until my palette has had more training, but then I said, screw it, I'm trying it. I loved Black XX Twist right away but one of the things that has always struck me (and partial reason for loving it) is the smell in the tin/jar. The smell is exactly like my dad's old shotgun cabinet when I was growing up. Now, it's possible my dad had smoked this blend or a close approximation and stored it there and it lingered. He did smoke pipes for a few years before I was born, but I'm doubtful he ever smoked anything too high end. This makes me wonder if there's something in the guns and ammo loading items, whether it be the powders, the cleaning oil, something in there that is responsible for this memory. Any ideas?
