💡 Did you know?
The marbling in Wagyu beef is so fine and evenly distributed that it has a lower melting point than other beef fats, which is why it literally begins to melt at room temperature and gives that signature 'melt-in-your-mouth' sensation.

FAQ
What does 'Aust. marble score 4/5' mean?
It refers to the Australian Wagyu Association's marbling scale. A score of 4/5 indicates a high degree of fine, white intramuscular fat streaks throughout the meat, promising excellent flavor and tenderness.
How is this different from regular ribeye?
While both come from the rib section, Wagyu has significantly more intramuscular fat (marbling) than a standard ribeye, resulting in a richer taste, softer texture, and higher fat content per gram.
What's the best way to cook this cut?
Due to its high fat content, it's best cooked quickly over high heat (grilling, pan-searing) to medium-rare or medium. This allows the fat to render and baste the meat without overcooking the lean portions.
