📍 Origin

Gunma Prefecture in Japan is one of the most renowned Wagyu-producing regions, known for its mild climate and carefully managed livestock diet of grains, corn, and rice.
The result: exceptionally pure meat with excellent marbling, aromatic flavor, and a silky texture.

🔥 Cooking Instructions

• Grill / Teppanyaki: 1–2 minutes per side (medium rare)

• Tataki: Sear quickly for 20–30’’ in a hot pan, then slice thinly

• Sous vide: 55°C for 45’, then caramelize with a blowtorch or in a pan

• Oven: 180°C for 10–12 minutes (for larger pieces only)

💡 Chef's tip: Wagyu A5 needs very little cooking — the goal is to melt the fat and release its aroma, not to cook it all the way through.
