"I was wondering if anyone has heard of a way to accelerate aging?"
store your cigars in cab style boxes,so that plenty of air can reach them.it allows young sticks to breath and mature more quickly,and I have found it can accelerate ageing for fresh cigars.
Six or seven months ago I purchased 3 bundles of fresh customs,which I mixed together with some 15 year old sticks.
So far the customs have not gone thru a sick period,and are still smoking like fresh customs.
Everyone who has had these customs has said they would be unsmokable from two months old until nearly a year old.
I have tried a lot of things in the 40+ plus years I have enjoyed cigars,these work best for me.........
