I've never went to the extent of freezing my sticks. I know many have great success with this process but in the years I've been smoking, I've never had any problems with just keeping the cigars stored the conventional way. I prefer about 65% humidity and temps usually don't get much above 70 degrees.

I remember years ago (when I once lived in Florida and this was a big concern for me) I was told the magic number of 140. That is, between your humidity and temp, keep the number at 140 or less and you should be fine. Now I know that is certainly not a scientific answer or approach, but I do believe it is a fairly good gauge to use.
