I was reading a magazine called Cigar Journal. It is an english/spanish magazine ( https://www.cigarjournal.com/about/current-issue/ ) . I don't usually find anything in it particularly interesting but this issue has an article on Maintaining the Aroma of Cigars. The author seems to have extensive experience with old cigars. His observations were interesting. I wish I could remember the details but I don't own that issue so I can't look back on the article.
Check it out if you can.
