Understanding Wagyu Beef Marbling: The Ultimate Guide

At The Carnivore Market, we take pride in offering some of the finest Wagyu beef available. But what makes these steaks truly special? The secret lies in marbling, the intricate webbing of creamy white fat that gives Wagyu its legendary tenderness, juiciness, and buttery flavor.

To measure marbling quality, Wagyu and Kobe beef use a Beef Marble Score (BMS)—a grading system that determines the richness and texture of each cut. Here’s what you need to know about Wagyu marbling grades and how they compare across Japan, Australia, and the U.S.

The Japanese Wagyu Marbling Scale

Japan is home to the most sought-after A5 Wagyu and Kobe beef, and their grading system is meticulous.

🔹 BMS Scale: 3 to 12 (Higher number = more marbling)

🔹 BMS 3 is the minimum requirement for Wagyu quality.

🔹 BMS 12 is extremely rare, with steaks nearly white with fat marbling.

Since more marbling means more tenderness, higher BMS Wagyu is more expensive and is prized by steak connoisseurs.

The Australian Wagyu Marbling Scale

Australia is one of the largest producers of Wagyu outside of Japan, using its own grading system known as AUS-MEAT.

🔹 AUS-MEAT Marbling Scale: 0 to 9+

🔹 BMS 0 = No marbling

🔹 BMS 9+ = Extremely high marbling

While BMS scores 10-12 exist in Japan, Australia caps its grading at 9+, meaning anything above a BMS 9 is grouped into the 9+ category.

USDA Grading & American Wagyu

In the United States, the USDA beef grading system focuses on three primary grades:

✔️ Select – Leaner cuts with minimal marbling

✔️ Choice – More marbling, juicier than Select

✔️ Prime – The highest USDA grade, rich with marbling

However, even USDA Prime steaks only compare to about BMS 3-4 on the Wagyu scale.

Since full-blood Japanese Wagyu imports were restricted in the 2000s, American Wagyu has gained popularity. These cattle are often crossbred with Angus, blending Wagyu’s richness with classic American steakhouse flavor. Like Japanese Wagyu, American Wagyu follows the BMS grading system.
