Brie <span class="style4">d'Affinois is similar to classic Brie in production, appearance, and flavour. Howver it differs slightly in its production method. Before cheese making the cow's milk undergoes a process called ultrafiltration. This removes water from the pasteurised milk, concentrating all other components. One effect of this process is that it allows the acceleration of the cheese making process. Whereas classic Brie takes eight weeks to make, Brie d'Affinois can be made in two weeks. Ultrafiltration also results in a milk that retains more nutrients and proteins, and the cheese has a relatively high fat content of 60%.
