I can't point to any hard numbers, but I think it's safe to say that among pipe smokers the ratio of facial-haired men as compared to the clean-shaven is probably much higher than among the public in general, and I can count myself among you lot with an unabashedly hirsute kisser.
I have recently noticed that anytime I smoke pipe tobacco with a pleasant scent (and not just "aromatic" tobacco, mind you), and for a while after, I compulsively curl my furry upper-lip up to my nose and take a whiff. I'm actually doing this right now smoking a sweet Japanese-market tobacco, its maple-syrup-y undertones readily absorbed by my 'stache.
And so, I have invented a term for this which I would like to officially introduce into the lexicon of pipe tobacco evaluation, fitting neatly alongside the well established scent descriptors tin-note and room-note: mustache-note. Of course, evaluating mustache-note makes one look ridiculous (in fact, I'm trying to commission someone to covertly photograph me in the act for your amusement), but not any more than, say, a wine enthusiast gurgling a mouthful of Riesling, or a "cupper"s hundred-decibel slurping of a fine espresso, and ultimately offers just one more innocently eccentric way to enjoy the smoking experience.
Assessing mustache-note requires no investment in new hardware, of course (in fact, you can go ahead and throw out your razors - a rather liberating experience), but should you feel the need to make a fresh acquisition to mark the beginning of your new life, we've around 200 pipes we're adding to the site today...
