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
Cheeses of Mexico cows’ milk, with some made from goats’ milk. More recently, efforts have been made to promote sheep’s milk cheeses. Most cheeses are made with raw (unpasteurized) milk. Cheeses are made in the home, on small farms or ranches, and by major dairy product firms. Between 20 and 40 different varieties of cheese are made in Mexico, depending on how one classifies them. Some, such as Oaxaca and "panela", are made all over Mexico, but many are regional cheeses known only in certain sections on the country. Some of the least common are in danger of extinction.
