Initial aging after their rolling is essential to allow the cigar to dry and stabilize. Not only will this greatly improve the flavor, but also greatly improve the burn and draw. Stabilization takes only 6 to 8 weeks, however allowing your cigars to age even longer will let the flavors of the blend meld and mellow into a more harmonious smoke. A cigar's complexities and nuances will be greatly enhanced with long-term aging in a proper environment.
Every cigar eventually hits a peak, and from there on it is downhill.
So it is just as important to not overage your cigars, as it is to age them in the first place. All cigars are better a year later in my opinion. This is a good time to start smoking those Habanos and Hondurans. This is also the peak period for many Dominicans, and most light bodied smokes. Typically the stronger fuller bodied cigars age better over a longer duration of time.
