The Longest any have aged once they have arrived in my humidor is about 1 year. That happens to be a CAO America I was saving for the 4th this year. I may have ruined it though. My 4th plans fell through so I didnt smoke it. That night I was carrying stuff in from my car, ran out of hands, and put it in my pocket. Before I made it into the house, My brothers friend backed into our ditch and I had to go push him out. It got a little tore up in the process, We will have to see if it still smokes well.
