Hard cheese is a type of cheese that has a low moisture content, making it firm and dense. It is typically aged for a longer period, which contributes to its strong flavor and crumbly texture. Common examples of hard cheese include Parmesan, Pecorino, and Grana Padano. These cheeses are often used in cooking, grated over dishes, or enjoyed on cheese boards. Due to their durability, hard cheeses can be stored for extended periods without spoiling. They are rich in protein and calcium, making them a nutritious addition to various meals.
