We have always aged our deer as long as possible, usually a week to 10 days if we do not have access to a walk in and temps. allow. Venison and beef have an enzyme that breaks down tissue making the meat more tender. Lamb and and pork lack this enzyme so once the animal is cool cut it up and freeze. I have been to a growing number of popular high end restaurants that to dry aging, under de-humidified and control conditions, steaks, usually New York Strips , that are aged up to 60 days. I have done up to 21 days with a Coctco N.Y. strip with awesome results. For venison and beef, aging is good.
