A lot of food tastes the best a short time before it spoils.

Fresh beef tastes good. One day old beef tastes like chewing on a rubber piece. Stored at the right temperature in a low moisture atmosphere for 4 weeks it turns into exclusive dry aged beef. One more week and it’s spoiled.

This is a different thing. It’s because it’s aged as a cheese wheel in controlled conditions, when you buy it, it’s not a wheel anymore, it’s been opened and you buy a wedge, hence it’s open to contamination.

It’s still unlikely for a 7 year aged cheese to go bad in two weeks unleass you store it unrefrigerated, but if you vacuum seal it, it will last a long time.

I know with veggies you can ferment them in a jar with the right amount of salt in the water. You just can never let them touch the air or the bad bacteria takes over.
Dry-aged beef has spoiled. The trick to it is that you need a fairly large piece, like a whole leg or side, and then you trim off all the bad stuff on the outside. More simply, they don’t butcher it then age it. If you go buy a piece of dry-aged beef it’s gunna act a lot like any other piece of meat but if it hadn’t been butchered you could just keep aging it beyond when this individual piece would have gone bad.
It tasts better before it spoils? Pffft please, who told you that?
And, here I’ve been leaving it out on the counter for a month before eating it. I just thought I didn’t like beef.
Just put some salt on it
Ahh, high meat. A man of culture. Gut culture, that isn’t endemic.
