Warped/Bowed Door fix?

I also think this is a moisture effect. If you store wine horizontally, the corks will breathe out a significant amount of moisture making the inside of the room pretty humid. That seems to have affected the door.

I am not sure that weights and the sun are needed. I wouldn't put the door outside unless the humidity is low. I think you need to take the door off, dry it out, and then seal the inside of the door. Oil finishes are not good moisture seals. I would use a low vapor poly - my favorite is Resisthane. It is categorized as a pre-cat lacquer which describes it's characteristics well but it is a water based plastic finish. I think you need the inside of the door to be completely sealed to resist the humidity from the wine. I would apply the same finish on the outside but it is less critical there. If you use a finish that gives off a low amount of fumes, like a water based, you should not hurt the wine.

You may be right about the wine moisture JimD. But what I can't figure out is that the door bows outward. In my way of thinking if the unfinished side of the door is exposed to excess moisture from the inside, then the grain should absorb it and cause it to expand, thus causeing the door to bow inward. Is my logic wrong here?

Incidentally, as a temporary fix, I have applied a nontoxic oil used for cutting boards on the inside of the door. It has reduced the bow in the door by quite a bit. It has not totally restored it by any means, but it at least it shuts easier now. I will eventually take it off and flatten as well as seal both sides as you suggest. We are in a heavy rain time for us, so I want to wait until w get to fairly dry weather again.

Wood shrinks as it drys. It grows when it is wet. I don't think there is a universal rule on what shape it will take. Probably has something to do with the grain in the wood.
