It depends on how many cigars I have. When I first started out, I struggled to wait to smoke one. If I want to smoke a cigar ROTT (right off the truck) and that is what I had at hand, I smoked it. If I have a choice, I let them sit in my wineador for a month or more before I smoke one, or I might smoke one within a day or two of receiving if the mood hit me.
I prefer at least 3 years on most of my Fuente cigars. They seem to age well and I am a Fuente whore.

If you buy a lot more than you smoke, time of rest becomes a non-issue.
