We're currently experimenting with infusing bourbon into cigars using a HumiForm Mini. Seems to be working very well with the filament on its lowest setting. Seems the higher vapor pressure of alcohol results in higher relative humidity than water for the same filament setting. When the lid is opened the aroma is awesome.
I purchased a produce keeper with vents on two sides that I lined with sheets of Spanish Cedar, and added a HumiForm on its lowest filament setting and a wireless hygrometer. This setup is able to maintain cigars in the 65% plus relative humidity range.
On Day 12, the humidor containing the two 84% RH pouches is showing considerable moisture content variation on the bottom, where the pouches are in direct contact with the surface. Moisture measurements include 9 points on the lid, 9 points on the bottom, and 4 points on sides of each humidor. One side of each pouch has been solidified since the first 24 hours of testing.
In future studies, we'll examine how much moisture variation occurs in cigars that are in direct contact with pouches.
