The marbling content of beef provides the excellent features of juiciness, tenderness and taste for which Wagyu has become famous. Grading of the beef is presented as Marble Score (MS) and is objectively measured by a specially designed carcass camera. The MS considers the quantity, distribution and texture of the intramuscular fat and is measured on the ribeye. A higher MS is associated with premium prices.
Wagyu beef averages between MS 4 to 6 which is very rare in other cattle breeds. Depending on genetics, nutrition and age at time of slaughter, scores up to MS 11-12 can be achieved. Above MS 9, the beef will be rare and extremely expensive.
