He said after 21 days the USDA Choice Ribeye he aged was every bit as good as USDA Prime.
My thoughts is that is a lot of time and space to take up in the fridge, vs just paying more for prime to begin with or be happy with choice. Now if it was better than prime it might be worth it for me...
my friend says what he likes is that by using the bag he could age the beef in his regular household refrigerator since he doesnt have an extra fridge. Just throw it in and walk away he said..
