As far as a higher temp boil, I don't know that it, in and of itself, is problematic, since meat stewed in a pressure cooker is often great. I imagine it is problematic for some other reason. Just my thoughts. Certainly the sauce is worse at a high boil because the fat and liquids emulsify leading to bad tasting shit.

i agree with most of this. but i have noticed on braises that are cooked too high that the exterior of the meat appears dried out. i'm not sure of the exact mechanics of why that happens, though. certainly, matt is right that too active a boil does free up a lot of scraps and debris from the meat, leading to a cloudy sauce.
