MOS Food Services Inc. (President and CEO: Eiso Nakamura, headquarters: Shinagawa-ku, Tokyo), the company behind MOS Burger, will launch a new limited-time product, the 'Black Angus Burger,' at MOS Burger stores nationwide (excluding some locations) from Wednesday, July 15, 2026, through early September. This burger offers a robust, meaty eating experience.

This launch features the 'Black Angus Burger,' crafted to highlight premium beef enjoyment. It uses Black Angus beef, known for its tender lean meat and rich natural flavor. The patty is seasoned with a special blend of spices and seasonings designed to maximize the inherent taste of the beef, delivering an appetizing, aromatic fragrance and juicy, savory satisfaction. The burger features a 'double sauce' system: a bold mustard sauce infused with garlic to enhance the meat's richness, and MOS's original Aurora sauce, which pairs perfectly with fresh vegetables. These two sauces work in harmony to create a well-balanced flavor profile where the meat and vegetables complement each other. This product is designed to provide hearty sustenance, helping customers power through the intense summer heat.

Key Features of the Black Angus Burger

【Feature 1】 Premium Black Angus Beef with Ideal Lean-to-Fat Balance

Black Angus cattle are a globally acclaimed breed, prized for their exceptionally tender texture. The meat has minimal gamey odor, with a superb balance of juicy marbling and flavorful lean meat—making it highly compatible with Japanese palates. The patty is seasoned with aromatic spices to highlight the beef's natural umami and savory aroma.

【Feature 2】 'Double Sauce' System: Garlic-Infused Mustard Sauce and Aurora Sauce

Two distinct sauces are used to enhance both the meat and vegetable components. First, a mustard sauce with a strong garlic kick that brings out the savory depth of the beef and stimulates the appetite. Second, the Aurora sauce, also used in popular items like the 'MOS Veggie Burger,' which pairs excellently with tomatoes and green leaf lettuce. By sandwiching the patty between these two sauces, the burger delivers a harmonious and layered taste experience that maximizes the flavor of each ingredient.

● 'Black Angus Burger' (730 JPY)

This burger layers original Aurora sauce, a Black Angus beef patty, cheddar-based sliced cheese, and onion slices, topped with garlic-infused mustard sauce, tomato, and green leaf lettuce. The patty uses high-quality Black Angus beef with an ideal balance of lean and fat, seasoned with spices to enhance its rich aroma and savory taste. Finished with the 'double sauce' system, this is a rewarding burger perfect for boosting stamina during the hot summer months.

*The cheese is pre-cooked at the factory.
