TFC Express, which already sells Kobe beef to Harrods and Selfridges, said the contract meant increased volumes would become available to multiples.
Kobe beef comes from the Japanese Wagyu breed of cattle. The meat is renowned for its high levels of succulence and has a price tag to match.
Wholesale prices for top end cuts are based on the marbling grade of the eye muscle, fat colour and flesh colour. Ribeye prices start at £60/kg, but cheaper cuts such as roasting joints are available from £15/kg.
TFC Express co-founder Leon Aarts said the company shipped the products chilled with full traceability. "All producers are inspected to ensure they meet our exacting standards. Product is only purchased once they comply with our standards."
