The launch is the first stage in a brand overhaul for the Buckinghamshire dairy.
The packaging has been redesigned by branding agency P&W. It features a farmyard gate, with the aim of highlighting Beechdean's rural heritage.
The product is being launched to mark the 20th anniversary of the Beechdean brand.
The company is looking to increase its share of the retail market to complement its foodservice business, of which the Tower of London is a customer.
