No, I didn't. I had problems with mold. So this could be the reason. Do mold infected cigars really smell sour?
That's good advice. Thank you. Some of my 8-10 years old cigars tasted sour, flat, boring or way too mild. I thought they were over the peak...
I have not seen any mold on my 2013 SLR DCs but thats one of the boxes that smells a bit sour.
