There is popular opinion that pipe tobacco improves in taste and value much like wine. One rationale is that the tobacco is vacuum sealed, which inhibits the tobacco from degrading and allows its flavors to blend more thoroughly. If so, why wouldn't the same be true for the coffee bean or the tea leaf. Also, when the tobacco ages, at what point does it stop developing or begin to degrade.
An individual conducting this test themself is likely to be biased to what they believe true about the tobacco's. If they expect it to be better, most likely it will be. The test would need to be conducted by someone unbiased to the tobacco or the tobacco owner.
My personal opinion is that tobacco would improve with age to an extent. I'm a new "piper", so my palate is not developed enough to pick up the subtleties in tobacco myself, but I would like to know of anyone who has had the opportunity to taste aged tobacco and compare it to the same blend of fresh tobacco. And I would love to know anyone elses opinion on the subject.
Here is why—-

Once upon a time in Weaubleau Missouri, I stopped off at a store on the way to deer camp and overheard a middle aged man say to a young man about my age then—-
Hey, where’s that movie star girlfriend of yours?
And the young man said that no account #%*^} screwed all my friends and when she left she took all my stuff and put a restraining order on me and my landlord evicted me and I lost my job and almost lost my truck. I’m just now getting back on my feet. I’ll have to archery hunt because I can’t own my guns again for six months.
The older man said, I went through all that.
What I did is find me an ugly woman. They are grateful to have a man. She cooks and cleans and has a good job and with the lights out you can’t tell any difference, you know?
You should find yourself an ugly girlfriend!
The young man smiled, and said I don’t think I’ll try that, but I’ll bet you’re right.
Men overpay for somethings and pay for them gladly.
