I am a real beef eater, love it. I often buy large quantities of various cuts, cryovac it, and let it sit for a while in the fridge. I seldom pass 40 days though, the flavor is not to my liking after that. I bought 15-20 pounds of beef ribs, some standard cut short ribs, some cut across the bone (Korean BBQ Style), and some full ribs. They were all cryovaced and in a 33 degree fridge drawer. I keep a thermometer to check the temp. I took it out tonight to cook it, and all three packages had a terrible odor. Two were 35 days old, one was 20 days old. They were all properly sealed. The meat had not oxidized at all. The odor was like human poop. No other way to put it. Not manure, not grassy or beefy, but poop. It made the whole house smell like a bad baby diaper. I rinsed it and rubbed it in cold water, no change. I cut off the outside, not help. I cut right to the bone, but the meat all the way in the center had the same odor. I am used to the smell of aged meat. Sometimes it can be a little offensive. This was not that smell. It did not dissipate like the bag smell will. The meat looked and felt pristine. Not slimy, good texture, firm fat. the fat was very light, like fresher meat. The juices were deep red, not at all discolored. Just a really terrible odor. I threw it all away, very reluctantly. Can anyone give me some input on this? The only thing I could think is perhaps the bones do not age well? I have aged bone in rib before with no problem. Does short rib not age well? Any help is really appreciated.
