Kinda old/kinda new guy here. Look alot and need to post more. Anyway, I have a "test" going on a 10-11# choice strip and boneless ribeye subprimal. I need to re-learn how to post pix and stuff here but if you go to this site http://www.drybagsteak.com/
you can get alot of info. It's a bag to dry age your meat in. If you check on the site, I plan on post'n a pic of each week. I started on the 16th and have a pic of day 6. I don't sell for them or anything, I'm just try'n it out and I give my honest opinion. If you have questions I'll answer truthfully w/out too much BS ;-). First time I've ever done this and I(nor my family) have had dry aged beef, that we know of. When we go out to eat we usually eat seafood cause we eat meat at home and it's hard to beat homemade.
Anyway, check it out. So far it was a real PIA bag'n the rib, it's in the second bag. The choice went great, but was my second try. I hope it works, so far so good. As I post it is day 9 and all looks good.
