I recently started an experiment on tubos. I have LRE 09 and MUR 13 Bolivar Tubos No1. They have a semi metallic taste that seems to be holding back their potential. I had one that had sat out of it's tube for awhile after traveling and it was not as bad. So in talking with some people for experienced than myself, I took their advice and have put them in a hermetically sealed food container with some cedar from empty boxes and a 72rh Boveda. Literally just did this so no reports yet, but maybe I'll post something when the time elapses and I have a conclusion. Pic attached for reference on setup. Bought food containers on Amazon for like $16. I store ALL my custom rolls in them with Bovedas as opposed to having them in my cabinets.
Tubos have been an enigma for me. I like the style, convenience, and ideal of aging in confined space. Unfortunately, the reality seems less attractive since it's higher price, more likely to inhibit mold, and now add this metallic taste to it. Especially Cohiba tubos that add 20% on cost in some cases. Coooooool factor...
@ApeSmokes your aging question is a loaded gun with answers that probably vary from person to person as you ask around. I've personally started using the food containers and have also upped the rh in my cabinets considerably after gathering info from more experienced people instead of trusting the dogma taught on most forums. I'm not going to say I have all the answers, but changing from 63% and slowly moving the needle to 70-72rh digital since I returned from Havana has led to a burn far superior to what I experienced before with less touchups, longer time between puffs without having to relight, and all around much more flavor. I also take cigars I plan to smoke and keep in a travel humi with 72rh Boveda and when possible let the humi sit in the sun to heat up for awhile before smoking. And if smoking an older stick or drier looking wrapper, I soak it with water prior to cutting/lighting to revitalize the wrapper. Love it.
As far as box aging, some people wrap with foil, others vac seal, some just put in humi as is. Some wait a few years for ammonia to escape, some say seal them right away, others don't.
I think I've learned the biggest key is to make sure you are going to age something good, because aged shit is still shit. Cigars are total ass now, maybe they'll be good in a decade? Then in a decade, maybe you didn't have them at the right rh? Oh wrapper won't burn for shit, probably need to drop your rh to 45% so that piece of leather burns? Perfect snakeoil disclaimer. Maybe they're just really shitty cigars with thick junk wrappers.
See above for what Cass has laid out....if you believe him that is.
