It really depends on taste and what you’re looking for in a cigar. If I had unlimited funds I would buy a dozen or so boxes of one cigar and wait a year between cracking each one so that by the end I was smoking cigars with a good 10 years on them. If you read MRN he says that you can even note changes in the 20-25 year time frame, but I’m dubious about that. But who knows what a really developed palate may notice. Some cigars are a waste of time to smoke young, like a Choix. I’ve had young ones with no flavors at all, and I’ve had 10 year old ones that have smoked like a dream and that’s been something that’s been consistent with every one I smoked. Cohiba is another brand that is a waste to smoke young, the grassiness overtakes the vanilla/bean/coffee flavors of them. Some cigars like the PLPC (new) are going to be just outstanding in a few years IMO. The ones I’ve smoked have had a very light sweetness to them with undertones of caramel. I don’t think there’s any hard and fast rule for how long any type of cigar should be aged. Obviously the larger the ring, the longer it may take them to evolve. Part of the fun of this hobby is smoking a few cigars across dates and seeing how the ageing process has affected the flavors.
