I cellar in order to future proof my hobby (habit ). The changes a particular blend undergoes in the cellar are variable both in magnitude of the effect and the time required to achieve a change. As with most things in this hobby YMMV.
One needs to be careful about comparing a 5 yo tin with a fresh one, there are lots of variables in play (besides aging), for example the recipe has been changed, or the raw ingredients changed -- after all tobacco is a natural product, not every harvest is identical to the last. Similarly I've found some blends I liked and cellared, 5 years ago are just so-so today, is that because of aging, my tastes have changed or a combination, who knows?
