If it stings, I count it as tongue bite, though it affects the gums and the rest of the mouth too. If I brush my teeth with peppermint-like toothpaste, and it stings all over again, that's bite. Interestingly, to me anyway, the worst tongue bite I've experienced was from holiday blends full of flavorings, and I think the flavorings were the worst offenders.
I've had mild tongue bite from both burley and Virginia based blends, but not often, and not much. I've had some strong burleys in which I would include Tambolaka the Indonesian air dried leaf, C&D Big'n'Burley, C&D Dark Burley and others, and I've had no bite from them that I remember. I'd say none.
Dry out your tobacco. Sip don't puff. Have a beverage with your pipe.
