Most cigars cigars improve with age...some more than others. Most domestics are ready to smoke when you get em. Cubans need to rest several years if they are recent production. all cigars change in time.

The best thing to do is buy a box and smoke one immediately. If it's not to your liking, let them rest. Smoke one every six months or so. When you think they have peaked burn em up.

I've got several cigars ten plus years old. They still change every time I smoke one.
