Me, when making a rib roast, I also like to “marinate” the roast for a few hours at room temp with garlic, olive oil, Worcestershire sauce, cracked pepper and fresh rosemary.
Why are you taking the roast off the rack when you lower the temperature? Seems to me you’ll end up “poaching” the bottom part of the roast because it’ll stay in the juices.
I assume you mean “brown,” not “braise.” Braising means simmering in a small amount of liquid. BTW, the main purpose of browning is to add flavor. It doesn’t seal in the juices.
Be careful not to overcook the roast. 130 degrees F is good for medium-rare. Let the roast rest for 15 to 20 minutes before carving to allow the temperature to equalize and the meat to re-absorb the juices - if you carve it as soon as it comes out of the over the roast will appear underdone in the middle and the juices will run all over.
I agree with NicePete that you shouldn’t let the roast sit in the bottom of the pan. You want to roast the meat, not stew it.
