From other answers I can see that fine grounded pepper looses its freshness and flavors so freshly ground is better.
Does this apply as much to coarse ground, I imagine when you bite it more parts of the pepper is newly exposed and the flavour will be better?
With some containers of fine ground i notice, after removing the lid there is a seal with foil paper. I imagine the fine grounded it and immediately sealed with foil paper to keep freshness and non exposure to air. Would the foil paper actually make a difference or should I consider finely ground in a bottle with foil paper still to have lost most of its flavour like those in packets?
