If there is one tragedy where a box of high-quality cigars is concerned it would be in their being ignored and going stale. While many people wrongly believe that a sealed box of cigars is impervious to many common problems, the fact of the matter is that they are not packaged to retain their best qualities. This is the reason that the best tobacconists keep their cigars in proper storage cabinets with humidifiers and hygrometers fully engaged.
Something to always consider when buying or receiving cigars is that they are extremely sensitive to environmental conditions and even when only recently removed from the store shelf they may be unsatisfactory for smoking right away. This might be due to the way they were stored in the tobacco shop, the conditions that existed during shipping, or the way your friend or family member kept them before giving them to you.
The next step requires you to buy a bottle of distilled water which is available at almost any pharmacy, and to dampen a brand new sponge with this water. Ring it out well and place this in the bag with the cigars, but be sure that the sponge is not in contact with any of them. Leave this setup in the closet for another week to ten days. This part of the process is going to slowly rehydrate the cigars without overdoing it and causing them to split wide open.
Once the initial rehydration process has been completed, you can then move them to the humidor that is actively humidifying its contents. Of course you still have another thirty days to wait before the cigars will have reached a decent level of moisture for smoking, but it is well worth the effort and the wait.
If you want to age cigars that have been dehydrated, you simply follow this same process and leave them in the humidor for another full calendar year. The humidity level must be at seventy percent and the ambient temperature at seventy degrees for the process to work successfully.
