I think boils (ha punny!) down to the difference between sanitize and sterilize. Drinkin' liquor (80 proof) is not strong enough to truly sterilize. We use 70% (140 proof) in the lab to kill bacteria, and still don't consider that truly sterilized. And especially since wood is very porous, that gives the bugs plenty of places to hide from any sanitizer - ethanol, Starsan, bleach, anything. Heat is probably best. I vote boiling it briefly.
Random Fact: Human Immunodeficiency Virus particles have approximately the same density of 1.170 wort. I know because I float them on a sucrose gradient in the lab to purify them for research.
Drinking: Belgian strong golden, Northern Brown, Porter
