Last night I was wondering how to get a better seal on mason jars and I found this http://m.instructables.com/id/How-to-vacuum-seal-a-mason-jar/ Seems like it’s easy enough to do. Would vacuum sealing a jar help with storage? Or does it not really matter? Figured I’d share!
Neat Hack, I don’t think it matters much. and seems like a pain every time you want to access your snuff.But for bulk long term storage it may be worth the trouble.
Now for Pipe tobacco you want the air inside your jar for the aging process can begin ."There are two types of fermentation that can change a blend- aerobic and anaerobic. Aerobic fermentation occurs in the American-style tins and in bulk blends put up in mason jars as these containers still have a fair amount of air in them. After the microbes use up the oxygen in the container, anaerobic fermentation will occur. Anaerobic fermentation is what will happen in the European-type vacuum sealed tins, and in mason jars where a vacuum pump is used to evacuate air, or by using heat to draw a hard seal."Russ Ouellette
Q: What about vacuum sealing?
A: Vacuum sealing is great for vegetables and coffee, but is pointless for tobacco. Tobacco needs some air to be locked in with it , at least to begin with, in order for it to age. A perfectly vacuum sealed container will likely keep the tobacco “fresh,” but it may not really age the way we expect it to. I’m more than a little suspicious about the heavy plastic “bags” used by most of these machines. They hold moisture in just fine, but they really don’t prevent gas exchange, and I’m not sure they’re truly able to stand the test of time. Tins are best. Jars are a close second. The special high barrier bags we used for a while for our 8oz packaging have several layers, each designed to be impenetrable to a different sort of molecule. I’ve conducted extended tests with this material, and am satisified that the tobacco will age nearly, if not as well as in the tins, at least for the short term. They are only slightly evacuted to facilitate packing and sealing. For best long-term aging, though, I still recommend tins. GL Pease
Agreed @basement_shaman. You can store snuff in tins and it will cause a hard seal on its own (drawing the pop up portion of the lid down flat) soon enough. No need to worry about it. I do disagree with Pease a little and with Russ a little on tobacco storage in jars but that will have to be another discussion later on. The science is right I just do it a little different and like the results so far.
