I’m a fairly experienced pipe smoker, about ten years in and tongue bite has never really been an issue for me. But somehow MacBaren Navy Flake, which I picked up on a whim, really has me stumped. I find it delicious but no matter how slowly I smoke it (I’m talking an hour and 15 for a single flake), I get a tingly and mildly irritated tongue. I have tried using it with filter crystals, drying the baccy, delayed gratification, same deal. Do I just give up, or is there hope?
