This has been a plaguing question that we've been answering for years - and rightly so! Keeping your prized cigars fresh is a challenge. Heck it's even a challenge at most cigar shops and cigar bars nationwide! But here in Colorado and other arid states have it extra rough. It seems like we are always playing a tortuous game of catch-up.
SEASONING There are a few rules to keep in mind if you own a standard, home-based, cigar humidor. First, you have to season it. Not once, but regularly. What is seasoning you ask? Seasoning is the act of throughly wetting ALL of the interior wood of your humidor. Be generous! The easiest way is to use a clean spray bottle and spray the interior until there is a pool of water at the bottom. Then do it again for good measure! You can also use a very wet rag to wipe it down. Go nuts! When you are done, close the lid and wait just long enough so that the wood is no longer wet to the touch. Now you can put your cigars back in there. You need to do this because the Spanish cedar inside of your humidor is very soft and porous - and dry! It will battle your cigars for the humidity you introduce - and it will win! Essentially, the wood will soak up all of the humidity and leave your cigars dry as a bone. To combat this we "season" the wood and fully impregnate it with water so that it doesn't steal them from your cigars. Feel free to do this as often as you want. Or at least every couple of months. Every couple weeks would be ideal.
