When I was heavily into cigars about 17 years ago, I would use this method to infuse cigars that I didn't like. The local B&M even sold kits consisting of a tall jar and a humidifier that you poured bourbon into. I made my own and would dip the head of the cigar in a shot glass then place the cigars foot down in the jar and seal it for about two weeks. It actually improved some of the cigars.
Ok its been close to a month, I removed the buffalo trace and the tobacco smells like an attempt to make FMC. It rehydrated my dry Star of the east extremely well. I let it air dry and off gas for 2 hours and then I jarred it up with a cobe of the whisky barrel stave thats been soaking in buffalo trace for a month. now to shake the crap out of it daily and let it sit and do its thing. I will update as soon as I smoke it. right now its too boozy smelling to try.
