I am posting this here as it seems the most appropriate place to get the most circulation among people who will be harvesting game.
I have been processing meat, (lamb, beef, pig) both on the ranch and working in packing houses. I have also processed game meat, mostly my own, for over 50 years. We used to "dry age" our meat in walk-ins, but having moved out of the livestock business, I no longer had a walk-in available to me. Used to keep a spare fridge for it, but again, really not big enough for a good size deer and definitely not an elk. Commercially about 8-10 years ago "cry" packs (short for cryogenic) for large cuts of meat came onto the market. A few years back, "wet aging" came into vogue with the ready availability of consumer vacuum sealers.
I have been using it for several years and as long as you keep your meat
clean and debris free, it works extremely well. On my latest elk kill, I packaged my meat and made lots of steaks out of the hind quarters and they now have 18 days of wet aging on them. I cooked one at 9 days and another today (18 days) and the difference in tenderness is notable.
It still requires a spare fridge maintained at ideally 34-36 degrees.
I will freeze the loin roasts and steaks at 21 days as they are inherently more tender by nature, let the hindquarter steaks go to 25 days then freeze them.
Here is the process as described by the "Meateater" bunch.
