Mold free here!
Just came up from my cellar to inspect everything for the first time in about 8-9 months and all is OK. The cellar stays in the 60's and is very dry. If it is not in a tin, I keep it in a glass mason jar. First, I took all of my square tins and wrapped them with tape. Been meaning to do that. One by one I went through the jars and it is funny the stuff you find you forgot you had.
Kinda hard not to open stuff and sniff it or take some back up but I have plenty to smoke upstairs. Lots of ropes, plugs, cakes, flakes and coins. All looking dandy. What I found interesting was that the only places I could get a sense of tobacco smell were the tubs that had tins stored in them!
Some nice plume on some G&H Brown Flake.
Considering what tobacco goes through drying, processing and storing, I think it unlikely that all tobacco doesn't have spores in it. Being super clean about hands, jars etc., doesn't hurt but unless they are filthy, I'm not sure it is a huge factor. The kicker is keeping it inactive. Don't give mold the conditions it wants. Cool temps, refrigeration even if you must, and pack tightly, keep the air away. If the stuff is overly moist, you might want to let it dry some in a clean area.
As to that smell, I guess the next time I dig the stuff out, I will probably put a tape seal on the round tins next. :mrgreen:
