Marbling is described by one of the following classifiers.
It has at least a slight amount of marbling.
It is fairly tender but because it has less marbling it may lack some of the juiciness and flavor of the higher grades.
This is a good option for backyard cooks.
Yield grade the amount of fat between the outside of the ribeye and the skin fat that would basically turn to gristle when the steak is cooked.
Beef cuts with less marbling such as usda select can be cooked on the grill just like usda choice or usda prime grades but may need to be monitored a little closer and cooked a little less to keep it as tender as possible.
Just over half of the beef graded each year earns this grade.
Usda select has only slight marbling.
Noticeable marbling but not a lot.
About 2 to 4 fat.
Usda prime beef has the highest marbling score or fat content followed by usda choice.
Marbling the amount of intramuscular fat in the section of ribeye inspected by the usda.
The ribeye muscle may be slightly soft and in carcasses having the maximum maturity for this class the ribeye is moderately light red in color.
