How the pig is hunted and killed has a lot to do with how it tastes. It should be easily understood that running a hog with dogs, and how it is eventually killed, in the sight and smell of man, isn't going to taste good compared to a naturally occurring, randomly foraging, at peace with the forest, shot through the heart (or spine or shoulder), dropped in its tracks, DRT pig.
The "Primordial Soup" of fight or flight adrenaline (and chemistry) being distributed in every artery, vein, and capillary throughout the muscles (meat) in the minutes (or hour) prior to death by dog run hog just does not taste good to the human palate.
Another bold and bad taste in hog is the number and placement of scent (musk) glands that if not double checked and removed before baking or roasting will poorly flavor every piece of meat on the grill or in the oven.
I am told that big old boar meat can be "seasoned" to taste significantly better if it is quartered, placed in a cooler filled with ice, the ice replenished as needed over three days, and the blood allowed to drain out of the muscle during that time. I have not verified this.
