How long can cigars be stored in the humidor?

Assuming that the humidor is in good condition and the humidification system is working properly, cigars can easily be stored in the humidor for many years. Even the best humidification system does not help, however, if there is not enough space in the humidor to allow the air to circulate freely. So it's important to avoid over-filling the humidor.

Most premium cigars should be aged at home in the humidor for several years to reach their peak taste.

A simple way to fully grasp the difference between a young cigar and one that has been suitably aged, is to buy a box of cigars and smoke them, one by one, over the course of months and years, keeping notes as your experiment progresses.
