How to fix dried up cigar without a humidor?

You can use your refrigerator but don't over do it. Be sure it won't be as good though.

No, no, no. Do not put the cigar in the fridge. Refrigerators are a very dry environment and will dry the cigar out. Go to your local cigar shop and get a humidifier "pillow". It is a small item that you soak in water for 20 seconds, then put in its plastic bag and put in with the cigar. Really, you should throw the cigar out if it is dried out, but if you really want to give this one a chance, try what I am suggesting.

Cigars can be properly re-hydrated without any impact on their taste or burn. Most cigar makers actually prefer a dry cigar to a wet cigar. All you need to do is take a humidifier (if you have one). If you do not have one then take a paper towel and wet it with distilled water. Place it in an aluminum foil, wrap it up with the foil and poke a few holes in the foil so that the water can gently escape. Place it in a zip lock bag with the cigar (the cigar on one side and the aluminum foil humidifier on the other). Seal the zip-lock bag and leave it in there for about a day. You are ready to go. Never push humidity into the cigar too quickly as that will cause the tobacco to go into shock and will burst the cigar's wrapper. The cigar will be back to new if you are patient. Never throw out a good cigar because it is dry. It always come back to life.
