I too have wondered the same thing.

People are used to the corn feed flavor of beef, chicken and pork.

You are what you eat is literal. I can taste the difference between valley deer eating soybean, corn and clover and mountain deer eating acorns and various different browse.

"Game taste" or "game flavor" to me is in the blood. The more blood I can get out of the game meat, the less the game meat tastes like beef liver or a similar dark, bloody cut of meat. I prefer to remove the blood. To each his own.

I agree with the above that acorn fed, southern Missouri venison tastes different from grain fed, central Illinois venison. I suspect this flavor is in the fat.
