There are many types of cheese, each with unique flavors and textures. Common varieties include cheddar, mozzarella, and brie. Cheddar is known for its sharp taste, while mozzarella is often used in pizzas and salads for its mild flavor and stretchy texture. Brie, a soft cheese, has a creamy interior and a white rind. Cheese can be categorized by its milk source, such as cow, goat, or sheep. It can also be classified by its aging process, with fresh cheeses like ricotta being consumed shortly after production, and aged cheeses like parmesan developing stronger flavors over time.
