I've got a question. I'm becoming cognizant of what I like and dislike and made my rounds, for the first time, re-purchasing, in slightly bigger quantities, those blends which I enjoy: Ebony, Dark Velvet, etc. My question is, over time, do most custom blends die out? Since I like those particular blends, instead of buying an Oz or two, should I be buying in much larger quantities and stockpiling? I figure the Captain and the Prince aren't going anywhere, but PipesandCigars Anniversary Kake, or other custom blends, should I be stocking up on preparing for their inevitable demise or do most shops keep their most popular blends on tap indefinitely? I'm trying to figure out where mason jars fit in with my particular style and I don't see any need to do that if I can purchase these as readily as I can a can of Coke when I run out. I don't have the forethought or space for a masonry jar collection. I view masonry jars as those tobaccos which are vintage and would be passing on in my estate. I think I would blow the lids off the jars within weeks of sealing them just due to sheer necessity. I'm only buying what I intend to smoke is what I'm getting at here, but I won't be if these blends have a production shelf-life. Thanks guys.
