Some aspects of cheddar cheese.

Cheese is one of the oldest, most nutritious and
versatile foods. It was a prominent article of
diet of the Greeks and Romans as early as 2,500
years back.
Though the actual origin of all the basic types
of cheese is unknown, most of them arose through
chance. As knowledge of the basic facts about
cheese-making advanced, it became possible to
evolve new types of cheese by modifying the
making and ripening processes of the established
varieties. There are hundreds of varieties of
cheeses with different names, but differing only
slightly in their characteristics.
