I always enjoyed the ritual of picking the stick, inspecting it, clipping it, taking a cold draw and then slowly lighting the foot by passing a lighter over it until I started to get a glow. Then a friend told me that he read that the "charring" of the foot could give an off flavor to the start of the cigar. I've done some reading since and have run across similar reports. Personally, I still enjoy the practice. What would be the difference between slowly and evenly lighting the foot or torching it as you draw? As long as it's done evenly. Either way you're burning the tobacco.
I was just interested whether anyone had a different take.
I guess it's kind of like warming the length of the cigar. I don't subscribe to the practice since I don't trust myself not to burn the wrapper, but if you can do it and not torch the wrapper, and it enhances the experience..... go for it......
