Bleu de Bresse (aka Bresse Bleu) is a milk blue cheese.
It is made in cylinders weighing from 125 to 500 grams.
Outside, it has a smooth, off-white rind similar to the rind on Brie and Camembert cheese. Inside, it is creamy and soft like Brie, almost spreadable, with patches of greenish-blue mould. It has a mild mushroomy aroma and flavour.
The cheese is made from pasteurized cow’s milk. The curd is made, cut and stirred, then turned, drained and salted. It is injected with the Penicillium roqueforti mould starter. Then it is moulded, then taken out of the mould, and dusted with Penicillium camemberti to grow on the outside and form the skin. It is aged 3 to 4 weeks, then packaged and shipped.
Gorgonzola, or another mild blue cheese.
Bleu de Bresse is a modern cheese, invented by the Société Laitière Coopérative Agricole de Servas in Servoz, Bresse in the Rhône valley of France.
In 1984, they tried to start calling it “Fourme de Bresse.” They were challenged in this by the makers of Fourme d’Ambert and Fourme de Monbrison cheese. The legal battle went on for a few years, until finally in October 1993 the “Cour de Cassation” forbade the Bresse makers from using the term and declared invalid the trademark they had tried to register for it. 
Eventually the cooperative grew into becoming the “Bressor Alliance”, which in 1990 associated itself with Bongrain company.
