Oh, but a "gamey" flavor does occur! It is caused by particular acids that build up in the system due to a rise in adrenaline caused by fear and stress. The longer the deer remains alive under stress, the worse the meat flavor can become.

Other things add to the "gamey" taste. The deer's primary diet is one. The fat on a deer carries a rancid taste. Blood can become rancid and cause a bad taste.

Of all, the acids cause the "gamey" taste most often.
