I don't have any self control. If a cigar ages in my humi, it's because other cigars in there have been more appealing to smoke.

I've smoked a Punch Gran Cru Vintage 2000 - that's about as old as I've gotten to go. James Suckling has a video of him smoking a really old cigar - I'll look for it and edit this post later if I can find it again.

A search should yield some great results for you. You don't need a fancy humidor to age cigars.
