I’m in the 2-4 times camp. Light... tap, then maybe once twice more. Perhaps dry out your tobacco a little more, or rethink your packing technique.
I always dump the ash halfway through a bowl as I find it tastes nicer and you get a better draw.So you never get to the point where there is so much ash you simply can’t relight???
I do, but only with certain tobaccos in certain pipes. I smoke SG 1792 flake in a big Chacom with a quite a deep bowl. That blend produces quite a lot of fine ash which occasionally can deaden the coal and stop the flame getting to it for a relight. If that happens i'll just invert the bowl and tip the loose ash out.So you never get to the point where there is so much ash you simply can’t relight???
