Deer meat is one of the essentials of life in this house! Congrats.
Venison's "gaminess" is affected by the sex and age of the deer killed. Generally in my experience, larger bucks have a tougher, thus gamier, meat. Does (plural of "doe, not "duz") and young bucks/yearlings, have the best meat. But it is in how it was butchered also. It can be dicey; if certain organs were hit in its getting shot, it could effect the meat. I would not eat any if it has a dark and bruised look to it.
