I know at one period they were into letting meat get high, or what we now would consider high, because it supposedly softened up tough and stringy meat and intensified flavor. I never tried it so who knows. I’m brave enough to keep and eat cooked chicken for more than three days though.

Aging a beef or deer sides & quarters?
I age deer quarters 3 days. In our college apartment, we took out the fridge racks and had deer quarters aging.
Some beef sides are aged several weeks before cutting up.
