9 Line Wagyu

9 Line publishes the thing most American producers leave out, which is where their cattle sit on a scale that has several rungs. Its own page sets them out: most Wagyu sold in the United States is an F1, half Wagyu and half Angus; F2 is around three quarters; and a purebred, in this country, needs to reach only 93.75 percent. Fullblood means every ancestor is Wagyu, with no other breed anywhere in the pedigree.

Read that ladder once and a lot of labels change meaning. Purebred sounds like the top of the scale and is not, and the gap between 93.75 percent and 100 percent is the difference between a herd with an Angus somewhere in it and one without. The farm states its herd is 100 percent fullblood, DNA-verified and never crossbred, and it says how few such cattle exist in the country, which is a claim that would be embarrassing to make loosely.

The cattle are described as dual registered as fullblood with both the American Wagyu Association and the Australian Wagyu Association, tracing to the original Japanese importations. Both bodies are pedigree registries: they record ancestry and parentage, and increasingly verify it with DNA. That is a strong thing to be able to say and a narrow one.

Neither registration says anything about how a particular carcass turned out. Marbling is an outcome of genetics, feeding and time, and a registry certificate is about the animal's family tree. A producer that is registered and says so is telling you the pedigree is checkable; whether that pedigree expressed itself in the steak is a separate question that only grading or eating answers.

The herd is described as founded on the Tajima and Kedaka lines. Those names matter because Japanese Black is not one uniform animal: Tajima is the Hyogo strain associated with fine marbling and smaller frames, and Kedaka, from Tottori, is associated with growth and size. Breeders balance them, which is why naming both is more informative than naming neither.

Tajima is also the bloodline Kobe comes from, and the farm handles that carefully on its own site rather than trading on it. Its cattle carry the same Japanese genetics, it says, and the difference is that only beef produced in Hyogo Prefecture can be called Kobe. That is exactly right, and it is the distinction this directory checks hardest, because place rather than pedigree is what the Kobe name protects.
