How the Japanese Grading System Works
The Japanese Meat Grading Association evaluates beef using two components. The first is a yield grade, scored A, B, or C, which indicates how much usable meat the carcass produces relative to its total weight. A is the highest yield, meaning more of the animal is premium meat. The second component is a meat quality score from 1 to 5, based on four sub-factors: marbling, meat color and brightness, firmness and texture, and fat color and quality. The combined score gives us designations like A5, A4, B5, and so on. A5 represents the highest yield with the highest quality, making it the pinnacle of the Japanese grading system and the most sought-after beef in the world.
Understanding the BMS Scale
Within the meat quality score, the Beef Marbling Standard is perhaps the most important factor. The BMS scale runs from 1 to 12, with 12 representing the most extreme marbling possible. To receive a quality score of 5, the highest, the beef must achieve a BMS of 8 or above. A BMS of 8 to 9 represents extraordinary marbling by any standard, while a BMS of 10 to 12 is almost beyond comprehension, with the meat appearing nearly white with intramuscular fat. For comparison, USDA Prime beef typically scores around BMS 4 to 5 on the Japanese scale. At Blu' Steakhouse in Hollywood, FL, the A5 Japanese Wagyu selections represent the top tier of this incredible scale.
A5 vs A4: Is There a Difference?
A4 Wagyu scores a meat quality rating of 4, which typically corresponds to a BMS of 5 to 7. It is still exceptional beef by any global standard and features marbling that surpasses USDA Prime. However, the step from A4 to A5 is significant. A5 Wagyu with a BMS of 8 or above has a completely different texture and eating experience. The fat is so abundant and finely distributed that the beef literally melts on your tongue at body temperature. The flavor is rich, buttery, and intensely umami with a sweetness that surprises many first-time tasters. A4 is outstanding, but A5 is a category unto itself, which is why premium steakhouses specifically source A5 grade.
Famous Japanese Wagyu Regions
Japan produces Wagyu in several prefectures, each with distinct characteristics. Kobe beef from Hyogo Prefecture is the most famous internationally, but Miyazaki, Ohmi, and Matsusaka are equally revered in Japan. Miyazaki Wagyu has won the prestigious Wagyu Olympics multiple times. Matsusaka beef, often called the queen of Wagyu, comes from virgin female cattle raised with meticulous care. Each region's cattle have slightly different genetic profiles and raising methods that create subtle flavor differences, similar to the terroir concept in wine. When dining at Blu' Steakhouse, ask your server about the specific origin of the Wagyu being served to deepen your understanding.
How to Eat A5 Wagyu Properly
A5 Wagyu should be approached differently than a conventional steak. Because of its extreme marbling, it is typically served in smaller portions, often two to four ounces at a time. Eating a 16-ounce A5 Wagyu steak would be overwhelming because of the sheer richness of the fat. It is best enjoyed in thin slices, seared quickly at high heat or cooked on a hot stone. Seasoning should be minimal, usually just a touch of sea salt to let the beef speak for itself. At Blu' Steakhouse, Chef Javi Cano prepares A5 Wagyu with the restraint and precision it demands, from the Wagyu Filet at $98 to the Wagyu Tomahawk at $500.
