Jochen, I always bring as many Romeo Y Julieta back with me as I can from Cuba whenever I go, and thoroughly enjoy them when I play my weekly poker match. In fact I went a little too far this time and brought back about 150 Cedros No 1 and 2s, which my humidor is too small for
As they are tubeless I guess I will just have to enjoy them a little quicker than I expected
They are Cedar wrapped though so I'm not panicking yet.
With regards to your point, there is a little debate over actual ph levels in cigars but one of the bigger clinical tests done recently, of which an abstract is available here
http://www.informaworld.com/smpp/content~content=a718863875~db=all , states that
"The smoke pH values of the smallest cigars was generally acidic, changed little across puffs, and more closely resembled the profiles previously reported for typical cigarettes. Interestingly, the smoke pH of smaller cigars and cigarillos became acidic after the first third of the cigar was consumed and then remained acidic thereafter, whereas larger cigars became acidic during the first third, then became quite alkaline during the last third."
So I guess we are both right smoke-wise
Although I don't tend to smoke the whole of the last third of my cigars.
But interestingly "The aqueous pH of the tobacco from the cigars also varied widely with values ranging from 5.7 to 7.8" That indicates to me that the
average non-smoked tobacco appears to be more often acidic than not. As a humidor should be kept at a humidity level of between 60 and 80%, there would be enough water vapour to absorb the acidity and transfer that to whatever
wood the humidor is made from. (Usually cedar, but obviously can vary)
So to summarise again, I would not risk acidic vapours having seeped out of the tobacco and into my humidor, but that is just my opinion.
