When I buy cigars at my B&M, no aging is necessary, they take excellent care of the cigars there.

When I buy online, I keep them in a completely seperate humidibag to quarantine and dry them out a bit. Online suppliers keep them a little wet so when they ship they don't dry out in the delivery truck. Plus, I am quarantining them just in case of beetles. I have 400+ cigars at risk, and all it takes is one infestation and you are fucked.

As for aging for taste - I have some very fine cigars, and some Cubans, aging in my small 70 ct humidor. I am aging those, have been for about a year. I try a few once in a while to see how things are going, and I believe most of them are improving with age. Once i figure out which ones age well, I will start using a larger humidor and see what 1-3 years of age do to my favorite cigars. And i age Cubans because more often than not, they drastically improve with age.
