FYI -- Smoking Pipes e-mailed an item from their blog today pertaining to anaerobic vs. aerobic aging (vacuum vs non-vacuum). I think the subject of the blog entry was buying tins vs. bulk. The advice on cellaring snuck in at the end. The intent to smoke the tobacco immediately or store it for future enjoyment was a deciding factor. My reading is the SP default position is this: Cellared bulk tobacco is best immediately transferred to a snugly packed glass jar and stored under vacuum conditions. So why not just buy and store tins, when available? Thrift, Horatio, thrift. Bulk buyers usually get more for their money.
