Tailgater, Good question.
In my experience, cigars can age side by side without any problems, providing of course that the cigars are not flavored, or scented. The "marriage" of pure tobacco is internal, not external. The most important, and often most overlooked issue, however, are the different conditions needed for particular types of cigars.
As you may have gathered, I am a big proponent of correct humidity levels and conditions for different types of cigars. So, rather than focusing on wrapper "contamination", cigar smokers should focus more on segregating their cigars into correct environments. Example: Heavy Maduros @60-62%, Cubans, Cameroons, Indonesian, and Rosado wrappers @65-68%, and Claros, Connecticut and Candelas @68-70%.
This way, you will always enjoy your cigars in peak smoking condition.
I hope this helps.
