Woof... 50*??
Did you mean 60, or is that not a typo? Cause that might be your problem. All of my cigars, if they're that cold, get dry, brittle, burn fast and taste bitter. If you can get your temp to around 60, or better still, 65, I think you may like these sticks better... Also everything from CI takes a little humi down-time, IMO (well... Everything from EVERYWHERE, if it wasn't a B'n'M.
See if you can't raise the temp, and give them some down time. Fingers crossed, because I love these sticks, so I hope you can enjoy 'em too!
