Roaring Forties Blue is an Aussie cheese hailing from King Island, south of Melbourne, at the western end of Bass Strait. The cheese is named after the infamous Roaring 40's westerly winds of more than 100km per hour that blow directly down the 40°S longitude.

Produced by the King Island Dairy, Roaring Forties Cheese is a handcrafted blue, made from the milk of cow's grazing on lush green pastures of the island. Cheesemaker Ueli Berger ensures that each of his cheese wheel is full flavoured with a sweet, slightly nutty character, a rich mouth feel and good aftertaste. For that he matures the cheese in a wax coating, which cuts off the oxygen supply and encourages sweet and fruity flavour. The wax coating also preserves the cheese's moisture and creates a smooth and creamy texture.
