I used to do this fairly regularly but not so much today. The technique I found the most convenient was to use the same spray bottle I used to dampen my beads. With the Vinotemp door open and as a backdrop, a couple of spritzes would do the trick. The excess would hit the door and help rehydrate my beads. I found this to have beneficial effect with many of the "sale" cigars from 99-00 production. But as I ran low on these cigars, I found it had less of an effect on fresher cigars. I never found any positive results on non-Cuban cigars of any age.
