What's better for using in a humidifier, distilled water or 50/50 solution? That is the question - and one that's been batted around ever since I got into the premium cigar business. I've had more questions about humidity control and humidifiers than any others, which is not surprising. After all, as avid cigar smokers, if our sticks aren't in tip-top shape, trouble follows.
When I started in this business they didn't have crystal-based or bead-type humidifiers. When you bought a humidor, if it came with a humidifier it was usually a green oasis foam unit (many manufacturers today still provide them with their boxes). Most experienced cigar smokers know that using 50/50 PG in foam humidifiers will eventually clog them. Now that crystal-based humidifiers are the state-of-the-art, the question also applies to them: Do you use 50/50 PG solution or distilled water? Since the crystals are made of polyglycol, one would logically presume that distilled water is all that's necessary. But some experts, including moi, have recommended 50/50 PG for crystal-based units. My hope is that this post will shed some new light on the question, and perhaps even put an end to the debate.
