I'll offer something that just made me laugh and prove how subjective beer sensory perception is. Two comments, from two different judges, from the same competition, judging the same beer: (1) Good, long lasting head retention, perfect for style, good carbonation; (2) Head quickly receded, exhibits very low carbonation for the style.
I submitted only two bottles, one of which had to be for the BOS round. Being that this beer didn't make the BOS round they clearly were pouring from the same bottle.
