How is blue cheese made today?

Legend has it that blue cheese was first made or discovered when a cheese maker left a loaf of bread behind in a cave in Roquefort, France. Upon returning sometime later, he discovered mold from the bread had covered and transformed the cheese. After trying it – and liking it – he decided to re-create it.

Today, blue cheese is made in a much more scientifically controlled fashion. Raw cow's milk, sheep's milk or goat's milk is pasteurized and treated with a starter culture that converts lactose to lactic acid and changes the milk from liquid to solid. Rennet is added to coagulate the milk and the curds are cut to release the whey. As the curds are formed into wheels, a blue cheese mold (Penicillium roqueforti) is added to the cheese before it is left to age for 60 to 90 days. During the aging process, the cheese is spiked with stainless steel rods that allow oxygen into the middle of the wheel and encourage the mold to grow. The result is the iconic blue veins within the cheese.

There are several types of blue cheese, with flavors ranging from mild and creamy to sharp and pungent. Roquefort, stilton, gorgonzola, and cabrales are among the most well-known varieties.
