Maduros can be more problematic.. especially the real leathery broadleaf's (CT, PA). Keep your puffs at 1 per minute at the fastest. Try and hold ash to an inch or so before ashing (I wouldn't risk longer than that with an unpredictable stick).
If I have a problem child, I'll gently blow on the area(s) that aren't burning in tandem with rest of the char line. That Tabernacle you had doesn't like a quick smoker. I also practically snort each and every cigar I smoke before lighting. At the foot, my nose is literally touching the long leaf while taking deep sniffs.
Depending on the filler, you can start to get a sense on whether certain sticks are wetter or not (with time and practice). There's a certain dankness you can get that is evident in wet cigars. After leaving out as I described above, it should dissipate some.
If it was stored too long wet, and that dankness has had enough time to permeate the filler all the way to the cap, it's done. You can't dry that out at that point. You'll smell and taste it the whole time.
Are all these sticks coming from a B&M?
