Most people love cheese, whether in chunks or strips, or melted on bread for a grilled sandwich. It is a part of the cuisine of nearly every culture, and variations on the theme are legion. Cheese is usually categorized into four types: soft, semi-soft, semi-hard and hard.
It describes the consistency of the cheese. Usually they are hard enough to easily grate. Cheeses such as parmesean, asiago, and romano would fall into this category. They are usually aged so more water leaves the cheese, thus making in hard as opposed to a soft cheese like goat cheese or brie.
