The Japanese Grading System
Wagyu grading is primarily based on the Japanese Agricultural Standard (JAS), a rigorous system that evaluates the beef’s marbling, meat color and brightness, and fat quality. The JAS system assigns grades ranging from A5 to C1, with A5 representing the highest quality wagyu beef.
Marbling
Marbling refers to the delicate streaks of fat that permeate the muscle tissue of wagyu beef. This intramuscular fat contributes significantly to the meat’s flavor, tenderness, and juiciness. The JAS system evaluates marbling on a scale of 1 to 12, with 12 being the highest level of marbling.
Meat Color and Brightness
The color and brightness of wagyu beef are also important grading factors. High-quality wagyu beef exhibits a deep red color with a bright, lustrous appearance. The JAS system evaluates meat color on a scale of 1 to 5, with 5 being the highest level of color and brightness.
Fat Quality
The quality of the fat in wagyu beef is paramount. High-quality wagyu fat is soft and pliable, contributing to the meat’s melt-in-your-mouth texture. The JAS system evaluates fat quality on a scale of 1 to 5, with 5 being the highest level of fat quality.
Other Grading Factors
In addition to the above factors, the JAS system also considers other aspects of wagyu beef, including:
