I have a 7 bone about 7 days into a 60 day age ATM and have done a few CAB 3 bones to 45 days.
You'll want to age whole roasts, not steaks themselves. There's a bit of trim loss when you dry aged and there would be nothing left if you did it with steaks.
You can do it with as little as a fridge with space that doesn't get opened all the time and has very good air movement around the roast in question.
That's a basic answer to your question. There's quite a few of us who have and do it so please post any follow-ups you might have :-)
. Here is my process ....including the learning curve
I did indeed. Sorry.Did you forget to post the link?
I followed Sous Vide Everything (YouTube) method with Umai Dry Age bags. Worked great and was really easy.
