I'm not into aging tobacco, but I am a moderate smoker, so when I enthusiastically buy a few tins, they can sit around for quite a while. Without unpacking my cellar tin by tin, I'd have to guess. I do have a tub of Half-and-Half that goes back several years. At the time, I should have spent a few more bucks at the J&S outlet and bought a tub of Carter Hall. It's an example of thrift gone astray. I keep hoping that the H&H Virginias will improve over time, but I think that's folly. On a brighter note, I have several blends that might actually improve with their several years of waiting, like McC's Dark Star and maybe my GL Pease Westminster and Dunhill Elizabethan. I'm not refraining from opening these, just not needing them yet. I have several jarred bulk blends and a still-ample selection of samples sent to me by a Forums member that delay my popping tins. I'm not roaring through my cellar, and I don't have a wall of tins, although I did admire the recent photo of foggy with his tall book cases full of McClellands.
