The answer to that isn't really black and white...and it isn't a stupid question at all.
As much as anything it’s personal preference but there are blends that benefit more from aging or cellaring much like a cigar would. Most aromatic blends (in general) do not change much with age...though it can depend on the method (Casing or topping).
Non-aromatic blends can change much like a well aged cigar can. The different types of leaf can either mellow out and/or marry over time creating a much different experience than a "new" blend.
Good evening from Greece, i am smoking Clan Aromatic in a Brebbia while drinking Kahlúa. I am not watching the "Eurovision" song contest because has nothing to do with real European countries and it's not vision but corruption and politics.
