"Little Joe Black Angus marbe score 4+ is naturally raised by accredited farmers in Southern Australia. The cattle is raised in a free range environment and fed only a pure grass diet." The tenderloin is the most tender cut of beef, the most desirable and therefore the most expensive. Because the muscle is not weight-bearing, it contains less connecting tissue, which makes it tender. With Little Joe, JBS has created a marble score 4+, which previously was thought to be impossible to achieve from grass fed cattle.
