So as some of you know, I went on a quest to try and find this stuff to try it out. I even bought a Cob pipe to try it in. Turns out I really like it. As in, I REALLY like it. When I do the math on the cost of a box with 6 pouches, it's not as expensive as I was led to believe. (about $4.11 per oz). So I'd like to buy more of this stuff but am wondering how long the sealed pouches last given all the crap they put into CB (Poly Glycol and Humectant)? I've seen CBW in Tins and also in the 6 pack sealed pouches. I would think it would last pretty long in the sealed pouches but I remember a recent thread where someone opened one up and it was really dry and tasted awful (ok, no comments like "how would they know the difference, there is no taste", "how could you tell that awful taste from the normal CB awful taste").
