Melted cheese is a delicious phenomenon that occurs when solid cheese is heated until it becomes a thick fluid. This process is influenced by the cheese's moisture content, age, and how it was curded. Younger cheeses with higher moisture content, such as mozzarella, melt smoothly and stretchily, while aged cheeses with lower moisture content, like cheddar and parmesan, may leak fat or fail to melt at all. The melting ability of cheese is also determined by its pH and curd size. The act of melting cheese has been described as seductive and delicious, with the term melty cheese sometimes used to describe cheese sauce.

What You'll Learn
The melting point of cheese varies
Moisture content is a key determinant of a cheese's melting point. A cheese's moisture content is influenced by the curd size, with larger curds leading to higher moisture content. Fresh, young cheeses are made with larger curds, which allow the cheese to hold together better and stretch more when melted. Dry, aged cheeses are made with smaller curds to remove as much whey as possible during the cheesemaking process, resulting in lower moisture content and a higher melting point.
The age of the cheese also affects its melting point. In fresh cheeses, the casein protein molecules are large and stretchy, causing the cheese to become stringy when melted. In aged cheeses, ripening enzymes break down the casein molecules into smaller pieces, resulting in a smooth, oozy melt.
The way the cheese is curded also impacts its melting abilities. Cheeses curded with acid, such as queso blanco and paneer, do not melt when heated because the acid causes the protein bonds to tighten and forces out any water. On the other hand, cheeses curded with animal rennet keep the calcium-to-protein bond intact, allowing the cheese to melt.
Additionally, the pH of the cheese, influenced by the amount of calcium in the curd structure, can affect its melting abilities. Cheeses with a lower pH tend to get gooier when heated but may not melt completely.
Different types of cheese have different melting points. For example, mozzarella, a fresh and soft cheese with high moisture content, melts at around 130 degrees Fahrenheit. Aged and dry cheeses, such as cheddar and Gruyere, melt at higher temperatures of about 150 degrees Fahrenheit. Hard, grated cheeses like Parmesan require even higher temperatures of 180 degrees Fahrenheit to melt.

Fresh cheeses like mozzarella are great melters
Mozzarella is made using a technique called "pasta filata" or "string dough". The milk is processed so that it forms elastic strings, which are then kneaded together into balls of mozzarella. This process is what gives mozzarella its signature stretchy texture when melted.
The age of the cheese also plays a role in its melting abilities. In fresh cheeses like mozzarella, the casein protein molecules are large and stretchy, tangling up to form a rope-like structure. On the other hand, in aged cheeses, these casein molecules are broken down into smaller pieces by ripening enzymes, resulting in a smoother, less stringy melt.
Additionally, curd size affects a cheese's moisture content and melting ability. Fresh cheeses like mozzarella are made with larger curds, which allow the cheese to hold together better during melting, resulting in a stretchier and pull-apart texture. This is why mozzarella is known for its excellent melting qualities and is often used in dishes that require a good cheese pull, such as pizza and fried mozzarella sticks.
The melting ability of cheese is also influenced by its pH level and acidity. A cheese made at a relatively neutral pH will have enough calcium bonds to keep casein molecules stiffly bound together. Adding some acid loosens the structure, allowing for a more fluid melt. However, too much acid can prevent the cheese from stretching and melting properly. Therefore, a good melting cheese requires just the right amount of acid to achieve that perfect, stretchy texture.

Aged cheeses have less water content
When it comes to the meltability of cheese, one crucial factor to consider is the moisture content, which varies across different cheese types. Aged cheeses, for instance, boast a lower water content compared to their younger counterparts. This characteristic arises from the fact that aging cheeses involves a dehydration process, where the cheese slowly loses moisture over time. The aging process not only reduces the water content but also transforms the cheese's protein structure, making it less elastic and more prone to breaking when heated. As a result, aged cheeses tend to become oilier and separate when melted, rather than achieving a smooth, creamy consistency.
The reduced water content in aged cheeses is a key factor in their unique melting behavior. During melting, the water in the cheese evaporates, and the proteins denature and separate. In cheeses with higher moisture content, this process contributes to a smooth, creamy melt as the water prevents the proteins from clumping together. However, in aged cheeses with less water, the proteins can aggregate more easily, leading to a greasy texture and a tendency to form lumps or separate into oil and solids.
Cheese with higher moisture content, such as fresh mozzarella or young cheddar, tend to melt more easily and smoothly. This is because the water molecules within the cheese act as a lubricant, allowing the proteins to slide past each other and resulting in a creamy, homogeneous melt. On the other hand, aged cheeses like Parmesan or aged Gouda have undergone significant moisture loss during the aging process, which leads to a higher protein concentration. This higher protein content can cause the cheese to become tough and rubbery when heated, as the proteins coagulate and contract, squeezing out any remaining moisture.
The type of protein in the cheese also plays a role in meltability. Casein, the primary protein in cheese, exists in two forms: alpha and beta. Alpha casein is more heat-sensitive and contributes to melting, while beta case casein impacts the cheese's elasticity and viscosity. Aged cheeses tend to have a higher ratio of beta casein to alpha casein, which makes them less prone to melting smoothly. Additionally, the calcium ions in aged cheeses can bind to the beta casein proteins, further reducing their ability to melt evenly.
To enhance the meltability of aged cheeses, it is recommended to combine them with other ingredients that can add moisture and prevent protein clumping. For example, adding a small amount of young, moist cheese or a starch-based thickener like flour or cornstarch can help create a smoother, more cohesive melt. Alternatively, shredding or grating the cheese can increase its surface area, allowing it to melt more evenly and reducing the likelihood of lumps or oil separation.
In summary, the lower water content in aged cheeses influences their melting behavior, making them more prone to oil separation and a less creamy texture compared to younger cheeses. Understanding the science behind cheese meltability can help consumers and chefs make informed choices when crafting recipes or creating dishes that highlight the unique characteristics of different cheese types.

Acid-curd cheeses don't melt
When most cheeses are heated, their proteins unravel and tangle up in a disorderly fashion, creating a molten mass. This is what we typically think of as melted cheese. However, not all cheeses behave in this manner when subjected to heat. Acid-curd cheeses, also known as cottage cheeses, are an example of a cheese that does not melt in the traditional sense.
Acid-curd cheeses are characterized by their high acidity and loose, crumbly curds. They are typically made by adding an acid, such as vinegar or citric acid, to milk, which causes it to curdle. This method of cheese-making results in a soft, moist cheese with a mild flavor. While these cheeses have their place in various dishes, they do not melt in the same way that a cheddar or mozzarella cheese does.
The high acidity of acid-curd cheeses is the key factor that prevents them from melting. The acid denatures the milk proteins, causing them to form a tight network of bonds that does not relax or unravel when heated. As a result, instead of melting and becoming fluid, acid-curd cheeses tend to dry out and become tougher when exposed to heat. They may even break down and become grainy or lumpy.
This unique behavior of acid-curd cheeses limits their use in recipes that require melted cheese. However, they can still be heated and used in various dishes. For example, they can be baked or fried, creating a crispy exterior while retaining a soft and creamy interior. They are often used as toppings or fillings, adding creaminess and a tangy flavor to dishes without melting completely.
