"PRIME Beef," the highest grade of American beef.

What is PRIME BEEF? It's a grade awarded to only the top approximately 10% of beef (as of 2025) after rigorous inspection by experts at the United States Department of Agriculture (USDA). It's the prestigious title of rare American beef that captivates the world. That's Prime Beef.
"PRIME" is the highest grade of American beef. The beef grading system was pioneered by the United States Department of Agriculture (USDA). The rigorous grading of each individual animal is proof of its reliable quality. The grades, from highest to lowest, are PRIME, CHOICE, SELECT, and STANDARD.
The deliciousness only found in PRIME BEEF. Maturity (youth): The younger the cow, the more tender and smooth the texture. Marbling: The richer the marbling, the juicier the meat. The grade is determined by the balance between maturity (youth) and marbling. Only beef that meets the conditions for Prime is certified as the highest grade. A perfect balance of finely textured, high-quality lean meat and beautiful marbling. The fine texture of the meat, unique to young cattle, allows the sweetness of the fat to melt when cooked, enhancing the rich aroma of the lean meat.
