Country of Origin: France
Bleu d'Auvergne is a French blue cheese, named for its place of origin in the Auvergne region of south-central France. It is made from cow's milk, and is one of the cheeses granted the Appellation d'Origine Contrôlée from the French government.
Bleu d'Auvergne is of relatively recent origin, developed in the mid-1850s by a French cheesemaker named Antoine Roussel. Roussel noted that the occurrence of blue molds on his curd resulted in an agreeable taste, and conducted experiments to determine how veins of such mold could be induced. After several failed tests, Roussel discovered that the application of rye bread mold created the veining, and that pricking the curd with a needle provided increased aeration. It allowed the mold to enter the curd and encouraged its growth. Subsequently, his discovery and techniques spread throughout the region.
