I have found the first (but I doubt it will be the last) pipe tobacco to give me the chemical reaction known as tongue bite - Sir Walter Raleigh Aromatic. It's a shame too, because up until I realized it halfway down the bowl, I had been enjoying the aroma and taste.
This wasn't a steam burn ... I did that on my very first bowlful when I puffed on it like a cigarette and basically boiled my tongue like a basket of crawdads. I think it was Balkan Sobraine, which tasted pretty good on the first puff. I ought to find the tin and try that one again, since I have no idea what it tasted like from the second puff onward.
Since I am still an unreformed cigarette smoker, I do light up a stick first thing in the morning to get the morning "kick in the chest" and calm the nicotine receptors enough to enjoy the pipe. If it's a rough morning I'll smoke two cigs before moving on to the good stuff. Since I still feel a bit clumsy with a pipe, I also smoke cigarettes when I am driving.
Back to the biter, the roguish Sir Walter ... I still have the 1.5 ounce pouch minus one regular bowlful. I know I will try it again - probably in a much smaller bowl - just because I am hard-headed like that and need confirmation. How soon I get back into the ring for another swing depends on how fast the Biotene works, and whether or not I find another one that bites. I have caught myself eyeing the pouch already this morning ...
