Less than 3 percent of all cuts of USDA beef qualify as Prime.
Choice is the second highest in quality. Most cuts of beef are Choice. These are very good cuts of beef that have a bit less marbling than Prime cuts. Choice cuts of beef can be sold in restaurants and supermarkets.
Select has even less marbling than Choice and is the lowest grade of beef that's readily available in stores. It is good, but lean and can be tough. Standard cuts are inexpensive and have almost no marbling.

Aside from marbling, other qualities that determine the grade of beef are the physiological age of the animal, its muscle texture, as well as color and firmness.Learn more about Meat, Poultry & Seafood
