I bit off a part of a guy's ear in a fight in AC just about 25 years ago when I was a bit of a dangerous psycho. [I bit into his nose as well.] I don't remember it having much of a taste, but the blood was somewhat salty.
I didn't swallow the ear, just spit it in his face. He was very scared and unhappy.
I have a great picture of myself from those "dark days" ... maybe I'll scan it and put it up on the "status" page ... I got an all-in-one scanner for "free with rebate" but I've never taken it out of the box. Maybe this weekend ...
