I agree with the premise it seems a bit short sighted to state "its burley, it won't age". A few months ago I asked a question
What to Cellar for Improvement?. Now the question on cellaring changed from what to age to what do you want to smoke in the long run and got because of the question deeper into the topic. Tobacco is never one straight leaf. The example is a flake, so several plants have to be dried, shredded to ribbons, pressed under steam and then there is no chance a few plants or leafs will get in with a somewhat other consistency or sugar content? Doubt it. Also if I look at the flake I see specs of different colors.
Now on the question of if the leaf is aged.... Doubt it also. There are cigar brands like Padron and certain Habanos releases that guarantee you a cigar which is rolled from 8 year old pillons or from a certain plant stock, specially fermented and rolled by the most skilled rollers. But these come at a hefty premium, the investment costs upfront compared to a younger and shorter fermented leaf are quite big. A tin of this is for me cheaper than a tin of HH Burley flake (for example) with a 2 euro margin between both. So why put the Aged in it? Because of the 6 weeks of pressing? Don't think so.
On the tobacco; I first found it boring, just earthy and flat, no cocoa which I look for when smoking a burley. Persistent as I am I have a tin open 3 months without jarring it and it hit a switch with getting a molasses / brown sugar sweetness. I actually enjoyed it now more, which shows for me the effect on opening it for a longer time. Still not something I would cellar, but still maybe a here and there additional to a TAD/Cellar order.
