I know, this will be wildly subjective, but I'm curious since my aged stock is getting depleted.
Tell us what smokes you prefer at sub 24 months old, and which smokes you ALWAYS defer to a minimum 24 months of box age. Give specific box codes if its not too much trouble.
For me; SUB 24 MONTHS: Montecristo No. 1 (BUM ABR 15), Montecristo No. 5 (MUL OCT 14), PL Montecarlo (EML JUN 15), and Cuaba Divinos (TOS JUN 16) have been quite good at sub 24 months, though I hope they continue to improve if I can keep my hands off them to let them age - NOT GONNA HAPPEN!
Cigars I will seldom touch young, requiring a MINIMUM OF 24 MONTHS of age are most Partagas, but especially the 8-9-8 Varnished (LAU JUN 16) and Lusitanias (no rececnt acquisitions). There is something magical that happens with these vitolas as they cross into the 4-5 year range. From my experience, Lusis continue to develop well past 10 and even 15 years.
Recent stock that I think needs more time is JL Seleccion #2 (SEA ABR 16), and RyJ Cazadores (ORG MAR 16) - though I never bought them before so I don't know how long they actually need. The Cazadores seems very flavorful, but a bit wild and inconsistent, so I think another 6-12 months would settle them down. The JL were consistent but very one-dimensional, straight and simple solid tobacco core. It seems to me the JL will open up and evolve a little over time.
