A calm barn, a tag on an ear, and a promise on paper. This food history documentary follows Wagyu from Hyōgo barns to grading rails, showing how proof, patience, and low-stress care build the melt people talk about. We explain breed identity, the long finish, Japan’s A–C yield and 1–5 quality grades with BMS marbling, and how protected names like Kobe are verified. You’ll see how global programs adapt the idea without losing clarity, and what chefs check before a cut hits the grill or hot pot. Bold claim: when names, records, and routine align, flavor is not a mystery—it’s a documented outcome.
