Just a few thoughts:
Arturo Fuente Chateau series (Chateau, Double Chateau, Cuban Belicoso, Royal Salute)...I don't think these cigars necessarily require aging before smoking. I can grab one right off the shelf and enjoy it while in the store. They do improve with age, but they are good tasting cigars without it.
Arturo Fuente Hemingway series...same as above. Never had a bad hemingway, fresh or aged. They taste better after a couple of years in the humi...especially the maduros. :love: However, they taste very good without any aging at all.
Padron 1964 Anniversary and Padron Serie 1926...if you want to spend a bit more money, both of these taste fine right off the shelf. They improve with age, but are excellent cigars from the get-go.
Padron (regular line)...I can also smoke these right off the shelf. They improve a great deal with age, but they are quite smokable right away.
There are many, many others that taste fine right off the shelf. It is a matter of taste and what you like in cigars. I personally believe cigars taste better with age (varies depending on the cigar), but others might not. No cigar NEEDS to age...most smokers just prefer the taste after they have.
Hope this helps.
