I agree with Old#12 ...the leaf WLT sells is already aged . I just noticed a bag of whole leaf I have has the date 2006 on it...I'm sure 2006 was the grow year, but thats 8 years old already, thats aged before it was rolled. The other leaf I blended it with to roll a stick was grown more recent than that but how long were the cigars (the store bought ones)tobacco aged before they got to the rolling table, before they left the factory, before they were imported, how long did they sit in a warehouse before they got to you. Time. Lots and lots of it. I wouldn't say that aging only mellows it out , but it matures . The leaf ,whether or not it's still a single freshly cured leaf or a combination of compacted fermented leaf we refer to as a cigar cigarette or pipe tobacco, has various aromas and flavors somewhere inside it . It takes a lot of time to get to the point where they come out in the right proportions and play along with the others by help of a flame and it meets the sensors on this piece of flesh inside our mouths we call a tongue . I've rolled a few sticks that were so-so immediately after rolling them. You know , I just couldn't wait to try my first one of the batch . I let the same blend sit and it gets better after just a week . I've also rolled a few that were great right off the bat. But set that stogie in the right temp and humidity in a spanish cedar box for a month...3 months ...a year . That cigar will only get better. Like a good wine. Yes , it does "mellow out", there are maybe a few points of sharpness ,tongue bite,etc, but the flavors get a chance to mingle with one another, to marry. Roll a few sticks lets say roll 5 clones to be exact. Smell and smoke 1 right away .Then put the rest in a box and take a good deep sniff , remember that aroma...ok, now set those other 4 aside and smell them again in a week, smoke another one. Its different. Now ,same process a month later.6 months then finally a year. You'll smell aromas you didn't notice that first sniff. You'll get a more improved "finish" . Age, my friend ...it improves ,it mellows, it brings all the flavors and aromas to the palate party.
I started out with WLT Sabroso Medio blend a year ago and even though I rolled them all the same way in leaf proportion, every time I smoke one, its different but better.
