Lately Forums members have subscribed to the benefits of aging burley. Burley has always been considered as keeping well. I haven't decided yet, because it seems to smoke extremely well when fresh, or aged, so I'm not sure aging is a big plus. That said, I confess I've had a tin of C&D Burley Flake #1 sealed and mellowing for two or three years. From my own experience, I feel I have a choice, it's a flip of the coin.
