Sour milk cheese Sour milk cheese Sour milk cheese or acid-set cheese is a cheese that has been curdled (coagulated) by natural souring or by the addition of lactic acid bacteria, such as traditional curd cheese or cottage cheese.

Most sour milk cheeses are white mould cheeses or red mould cheeses, and many are flavoured
