I smoked a Juan Lopez Petite Corona today and it was musty tasting. I've smoked several others from the same box and hadn't experienced it before with them. I noticed a Montecristo No.2 and a Partagas Series D No.4 had the same mustiness a while back but others from the same box that didn't. What's this from? I keep everything just below 65% and about 68° so I think the conditions are correct.
