A fresh cigar is not the same as a “well conditioned” or “well kept” cigar.  “Fresh” refers to a cigar that was just made: “right off the bench”.  Typically fresh cigars are at much higher humidity levels and are not ready to be smoked: a post production aging  (Añejamiento)  will be necessary for the flavors to blend and synergize.

Under proper conditions, a cigar can age and develop for a lifetime.  Essentially, aging cigars is the very slow process of organic decomposition, also known as Añejamiento.  In that process, the flavors of the leaves will continue to marry and refine.  Over time the cigar and wrapper will exude oils and develop a richer, glossier sheen.  The flavor and aroma changes a cigar will go through will vary by brands and are impossible to predict.  For that reason, cigar connoisseurs enjoy aging their cigars to experience the surprising nuances that develop.
