Do fluctuations in temperature over time effect the taste of a cigar if the moisture level its holding stays the same? My knee jerk reaction first thought would be that as long as it has a day or so to stabilize at a normal 70 degrees it would be fine... I'm certainly no expert though.
also most people let cigars they get rest for several weeks so they stabilize to the RH in your humidor. most people go with 1% humidity a week so depending on your set up it can take several weeks for them to stabilize.
Happiness? A good cigar, a good meal, a good cigar and a good woman - or a bad woman; it depends on how much happiness you can handle- George Burns
