Smelly Humidor ?

For what it's worth, someone on another forum did a "coffee" infusion test where they actually went as far as putting the cigar fully submerged in coffee grinds for a few months..

When they opened it, it still smelled like strong coffee.

The Cigar hadn't changed one bit.

That being said, I would suggest seasoning the humidor to get the wood to open up a bit, then I would put the baking soda in there in a small bowl.
