At college, a kid in the dorm used to get care packages, often containing a tin of cookies. The lid was closed on a sheet of wax paper, underneath that was a slice of bread covering the cookies. The slice of bread was always dried/stale, while the cookies were fresh and delicious.I am definitely not an expert on this but a slice of white bread has help me save some old Sugar Barrel.
I don't know if that is how I'd describe it, but I've never liked the result of rehydrating.In my experience. Rehydrate tobacco with distilled water makes the taste of tobacco fades.
Having grown up in South Carolina I remember that tobacco farming ranked up there with cotton in the 60's. Any tobacco farmer of any size had their own barns where they hung the tobacco to dry. Even as a youngster in the 50's & 60's the aroma in those barns were things of fond memories.Years ago, before bulk barns, we cured tobacco on sticks. After curing we had to open the barn doors during the night to let the leaves obtain some moisture and become pliable so they didn't crumble while unloading the barn and hauling to the pack house. That's how I handle dry pipe tobacco. I pour the crunchy tobacco into my wife's biscuit pan and place it on the porch overnight. By early next morning, if pinched between the fingers, it will hold together and be soft. I just place it in a mason jar and seal it up. This works because the tobacco will only absorb the moisture amount it needs and is never introduced to liquid All that's left is washing biscuit pan and slipping it back in the kitchen before she's any the wiser.
The first sentence is so wrong it's criminal. 10-14% is the moisture content; RH @70º would be a range of perhaps 60-80% RH. There are tables showing conversions, but my example is made up.Per the article: "The proper RH of pipe tobacco is only around 10-14%." This seems off to me because 1) in most areas the average RH in the atmosphere is much higher, and 2) RH refers to atmospheric moisture, not moisture in a solid (which is "moisture content"). I have read that the moisture content of pipe tobacco should be around 18-22%. So, about 1/5 of its weight is water.
Not a surprise, and not confirmation that bail tops are poor containers for tobacco: They are quite good except for l/t storage, but also if used for a bowl full a few times a week or more.In any case, the article is still very helpful. The RH where I live is very low, and I have some spritzing to do. I have been sealing my tobacco in mylar bags, but have a pound of flake in one of those hinged and gasketed glass jars that's become downright crispy in just a year.
Recently I’ve experimented with something similar: little containers of salt and drops of distilled water. Table salt should keep the RH at 70%, and I had more water slowly as the tobacco takes the humidity down. within a few days it it stabilizes and I know the tobacco is rehydrated, but not too much.
