Cheese ripening the cheese by fungi to occur. Mould-ripened cheeses ripen faster than hard cheeses, in weeks as opposed to the typical months or even years. This is because the fungi used are more biochemically active than the starter bacteria. Where the ripening occurs is largely dependent on the type of cheese: some cheeses are surface-ripened by moulds, such as Camembert and Brie; and some are ripened internally, such as Stilton. Surface ripening of some cheeses, such as Saint-Nectaire cheese, may also be influenced by yeasts which contribute flavour and coat texture. Others are allowed by the cheesemaker to develop bacterial surface
Cheese crystals Cheese crystals Cheese crystals are whitish, semi-solid to solid, slightly crunchy to gritty crystalline spots, granules, and aggregates that can form on the surface and inside of cheese. Cheese crystals are characteristic of many long-aged hard cheeses. Hard cheeses where cheese crystals are common and valued include comté, aged cheddar, grana cheeses like parmesan, grana padano, and Pecorino Romano, as well as old gouda. However, in some cheeses, like industrial cheddar, they are considered a production defect. Cheese crystals can consist of different substances. Most commonly found are calcium lactate crystals, especially on younger cheese, on the surface, and on
