Aging tobaccos was a complete freak of production. There's no exact science to any of it. Tobacco all goes through three sweats before it is fully cured, and sometimes aged two m ore years before being used in production, sometimes farmers will set on a crop for years waiting on prices to go up or saving up for a larger bankroll at one time. Then when it's tinned, some vacuum the air out, some add air, it's all inconsistent. And, intentional aging of tobaccos is a game of risk. While I have not personally tasted a blend that went bad, I will acknowledge that it is a possibility. Turning vile? I have to wonder what that even means. I conjure up tastes of Lakelands swamped in grandma soap. Besides a Lakeland, I've never tastes a vile tobacco. But, sure, maybe it's a possibility. However if that Capstan was vile, I want to swim in a sea of that sweet gorgeous smoky vileness... naked.
But, yes, every manufacturer will say that their product is ready to smoke right away. And, if you don't like it fresh, you probably shouldn't waste time and money on aging it. But, with potential for price changes, my getting very damn close to retirement budget, possibilities of tobacco being restricted from being able to use the mail, or just some sort of anti-smoking apocalypse, there are plenty of reasons to set tobacco back. Aging it, is just the freaky side effects of this.
Smoke it now, a year, 2, 4, 8, 20, whatever you want. Explore the tastes. Try new things. I am a butterfly pipe smoker, lighting on this taste for now, then fluttering over to that one. I live for the experience.
