What is difference between those types of cheese ?

Explanation

a. The difference between these types of cheese is due to different microbes used to make them and the time for which they are ripened. This gives them a different texture and taste.
b. Cottage cheese, cream cheese, mazzarella are the soft and fresh type of cheese. If cheese is ripened for 3 to 12 months, semi-hard Cheddar chees is obtained and if rapened for 12 to 18 months, Parmesan cheese is obtained, which is harder than Cheddar.
