I'm hearing a lot lately on the youtube about cigar purging. Even a video about how it burns off ammonia or something.
It just reassures what cigar smokers know about resting and puffing a cigar; and how much the wrapper plays a part in the taste.
So when you purge, you are as it seems to me, igniting the blend. So after purging, you are then burning the wrapper. when purging you are insulating the inside and then when puffing you are igniting the wrapper and tasting it all together.
I dunno, just something i notice. I do blow through the cigar time to time and notice. just my cents. keep smoking brothers and sisters
