Cigars and the "marrying" thing
I've been asked about the marrying thing a lot, and I know there are some cigar smokers who are particularly finicky in this regard. A few have told me that they have special sections in thier humidors and/or separate cigar humidors just for their maduro cigars, their Nicaraguan cigars, their Cuban cigars, whatever, and have even described other variations of cigar segregation too numerous to mention.
I've been comingling my cigars in my humidors for years and I've never noticed any distinct difference in the way they smoke or taste. Perhaps there is some credibility as to the "marrying" with other tobaccos over long periods of time, but from my experience the cigars don't seem to be affected much at all. If anything, they taste better.
I advised the writer to put some cigars of varying brands in his humidor with their cellos and some without. Then, after a few months, to smoke one of each and compare to see if the flavor was affected in any way.
