Great ideas about helping the meat after the fact, marinades and all. Venison does pick up the flavor of the feed. Our local butcher has shown me via smell tests deer that come from swamps and have been eating swamp plants you can smell swamp in the meat. The deer I shoot have been eating my apples all summer and have a distinct apple flavor. After all the great ideas herein this string of posts are tried and venison is still gamy to your wife there is one sure fire solution. Shoot a 3-4 month old bambi . You can not beat the mild flavor and all cuts are tender without any fuss or muss.
