Venison is like any game meat, it really depends on the quality of the animal you take down. It can also depend on what wild diet that deer has had, what age it is, what gender it is, how well it was field dressed then hung and butchered. Then it comes down to the skill of the cook and preparing a cut of meat properly allowing for it being lean wild game and what part of the deer it came off of. Do it all right and you have some of the best, healthiest meat you could ever eat.
The best venison I ever had was years ago. We had a family member who ran a blue ribbon herd of beef cattle on his farm. He never allowed hunting but over the years the white tail population on his farm literally exploded. Those darn deer were hopping fences to steal his top quality cattle feed, use the salt licks and sip at the cattle water tubs. He finally decided a controlled hunt would be best to cull them back a bit.
That venison, from deer never hunted, never stressed by harsh conditions, that were feeding off the best wild and farm feed to be found was literally to die for......yummo!
