Gosh, tsuwm, philtrum is just so danged clinical! Completely unpoetic. It sounds like something one would use in a laboratory.....something one would, at best, brew a concoction in.

But here's another beer word for you:

wort n. -- fermenting malt, incipient beer; anything fermenting

...from that old word tippler, Mrs. Byrne.
