What is Green cheese?

Green cheese is a fresh cheese that has not thoroughly dried nor aged, which is white in colour and usually round in shape. The Oxford English Dictionary gives a reference from the year 1542 of the four sorts of cheese. The first sort is green cheese, which is not called "green" because of its colour but for its newness or under-ripened state, for the whey is not half pressed out of it yet. The phrase is not commonly used to describe the colour of a cheese, though there are some cheeses with a greenish tint, usually from mold or added herbs. There are other instances in which the word "green" is used to mean "new", such as in the term "greenhorn", which refers to an inexperienced person.
