I have been smoking this blend for a few years and I have a question about why the blend seems to improve so much after roughly a year or slightly less in a mason jar. I like it 'fresh' as well, but after almost a year, the blend just becomes deliciously smooth. Looking on TR, some reviewers note this too but none offer a reason. When I examine the constituent tobaccos in it, I am left wondering why does it age as it does rather swiftly. Any ideas?
