Wagyu is a Japanese breed of cattle. Wagyu were originally draft animals used in agriculture, and were selected for their physical endurance. This selection favored animals with more intra-muscular fat cells - 'marbling' - which provided a readily available energy source.
The higher level of marbling provides more flavor, juice, and tenderness, and it is also healthy for you. It is lower in cholesterol with higher percentages of omega-3, omega-6 fatty acids, and monounsaturated fats.
Japanese cattle have four breeds, Atlas has the Japanese Black cattle with the bloodline.
There are 3 levels on the USDA scale for meat quality - Select, Choice, and Prime. Only 3% (roughly) of the traditional US cattle grade as Prime. In 2008, the Japanese Meat Grading Association raised their grading standard so that the BMS (Beef Marble Score) goes up to Grade 12. At Atlas, our meat continually grades at BMS level 9 or above, providing more flavor and tenderness in every bite.
