On the Full Blood Steers we have found that the different fat profiles, AA, VA, VV appears to make a big difference in the flavor of the beef. AA being the preferred that type.
Even the steers that we process get DNA tested for fat profiles and tenderness.
We believe that there is a difference between the flavor of breeds and crosses ...there all good, but there is definitely a difference in taste, tenderness, and fat type.
We pull one steak from every steer we process to sample, record picture, check marble fineness, basically a quality check. We always cook them the same with no spices or anything on it.
It's kind of ironic, but the best steer we ever raised was one we sold, of course you don't know until you eat that sample steak.
