Mishima Reserve cattle are long-fed a carefully managed diet of grasses and grains and raised up to a year longer than the American standard. By allowing the animals to gain weight slowly, Mishima Reserve maximizes development of the superior characteristics of the prized wagyu breed. In fact, it's during that extended year that some of the most important qualities of wagyu begin to develop, including the marbling. This last stage is also when nature works its magic, transforming the composition of the fats themselves by increasing the ratio of unsaturated fats and the omega-3 and omega-6 linoleic acids present in the meat.
