Deer doesn't benefit from aging like beef does as there is no fat in the meat. This is why I do my deer when they are warm and easy to skin and boneout. The secret to making deer taste really good is to soak the meat inthe fridge in salt water for 4-5 days dumping the salty, bloody water off every day and replacing with clean salt water. The salt water draws the blood out of deer and by doing so draws the "gamey" taste out of it.
