RH revelation

[vortex]

I think I know why many prefer their RH at or below 65% - it's correct for their temperature!

Check out this page:
http://www.cigarsofhabanos.com/cigarinfo.asp

After viewing this chart relating what RH is required to equal 70% RH at 70 degrees (13.15mmHg), I realized this explains at least two things.
1. Why many people prefer a lower RH than %70
2. Why my cigars are sometimes too moist or too dry.

I knew of this relationship but did NOT know the degree to which it can make a difference.

I.E.

At 68 degrees a 75% RH is required and
at 72 degrees a 65% RH is required!

Almost 5% change for every 2 degrees!

This may explain why many find their cigars more smokable at 65%...

Thanks for this link,seems it was in my bookmark folder but I have not read it.

I still like my gars between 65-70.When they are kept on the low side they tend to be harsher and dry tasteing.I fear loseing essential oils as has been the case in past experiances.

Thanks again for the link,very interesting indeed.

Disregard that chart. I have no idea why it is propagated all over the net but I do know it is total bs. I keep my humis as close to 60% as possible regardless the temp and they always smoke fine. During the winter my basement gets down to 55. Going by that chart my sticks would need to be dripping wet. RH is just that, relative humidity. It's all you need to know.

Interesting. It may be there is truth in between, too. I looked for this because on a cold night I noticed my RH dropping quickly with the temp so I realized there must be SOME kind of relationship. But it may not be as simple as this chart suggests. But it did explain many observations that had baffled me. As is the case so often with extreme explanations, the truth lies in between somewhere.

Thanks for your input!

Technically that’s right and backwards and the wrong application. If you have a humidor at 70F and 65% RH raising the temperature will cause the RH to rise along with it. Same with lowing it. But we just shoot for maintaining so 65% is what we keep it at through out. That’s why people like beads; they give and take continuously to keep the 65% regardless of the temp.

Don't get me wrong. Your RH will rise and fall with temperature changes. My point was you want to try and keep your RH at your desired level regardless the ambient temp. As Mrepp stated, he likes to keep his at 65%. As Jack Sparrow would query, "Savvy?"

See this post from last year.

I could go into an explanation of why Relative Humidity is the correct property to control, but trust me on this one, it is.

The key post in AVB's link is a bit hard to read but right on the money.

So I suppose the only reason I saw RH vary with Temp is because the beads were just lagging behind in adjusting for the change and would have equilibrated at 65% eventually. Also, for all practical purposes, RH is the important thing and not the partial pressure of gaseous water when it comes to cigars.

Bottom line: the chart has no relevance to cigar storage!

Wow! thanks for posting that. Now I know why I can never get 70% in my room because it's always 74F in there.
