What Percentage of your cellar are tins or bulks?

It's a loaded question, and so I've aged tobaccos 4-5 years unopened in both ways. Some with an inch of airspace in the head, and some packed entirely full. Honest opinion is I think the entirely packed tight jars seem to age better and more slowly, while Virginia based mixtures with an entire inch of air left at the top tend to get a lot more fermented and sour and rotten fruit-ish.

It's a loaded question because you have aerobic and anaerobic aging processes and the aging is going to end up slightly different doing it various ways. I've also been able to somewhat stop the flavor changing in my long aged experiments by drying down tobaccos nearly crispy before jarring them. One example, I did with the first year 2016 release of C&D Small Batch Carolina Red Flake. I've got some that still tastes nearly fresh because I dried it before jarring to prevent molding issues, and then I have some moist jarred for the same amount of time that tastes entirely different, darker, and not nearly as good by any means. Muddied in many ways, vs what you expect from a red and bready high sugar VA when somewhat fresh. I wanted to capture that flavor and unfortunately I may be disappointed with the many tins left in tins if they did not convert anaerobic quickly within the first year inside the tins. Fingers are crossed, though.
