Cheese sweats are real and can occur in two ways. Firstly, some people may experience gustatory sweating, or cheese sweats, after consuming cheese. This is a medical condition known as gustatory hyperhidrosis, which is sometimes connected to nerve damage and conditions such as diabetes. However, this phenomenon is rare and generally occurs due to volatile organic compounds in the food. Secondly, cheese itself can also sweat, which is caused by the release of moisture into the air. This happens when cheese is kept at room temperature for too long and is more common in high-fat cheeses. While sweaty cheese is mostly safe to consume, it may not be aesthetically pleasing and can impact the flavour and texture.

What You'll Learn
Sweaty cheese is generally safe to eat
The main reasons why cheese sweats are fatty acids and condensation. Fatty acids are released when casein proteins in the cheese loosen up as it reaches room temperature. These acids then rise to the surface as small drops of oil. Condensation occurs when cheese releases water vapour, which can become trapped if the cheese is wrapped in plastic, leading to the formation of condensation on the surface.
To prevent cheese from sweating, it is recommended to limit its exposure to heat. Only remove the cheese from the fridge when you are ready to serve it, and avoid returning it to the fridge after it has been taken out. If possible, serve cheese indoors, especially on warm days, and consume it promptly.
Additionally, the type of cheese can impact its tendency to sweat. High-fat cheeses, such as hard cheeses and sheep's milk cheeses like Manchego, are more prone to sweating. On the other hand, pressed cheeses that are low in fat are less likely to sweat.
While sweaty cheese is generally safe, there is one important caveat. If the cheese is left for an extended period, it can become mouldy, especially if it is covered with plastic wrap or a cling film. Therefore, it is important to inspect the cheese for any signs of mould or discolouration before consumption.

Cheese sweats due to condensation and fatty acids
Cheese sweats due to two main reasons: condensation and fatty acids. Firstly, condensation occurs when cheese releases water vapour, which can lead to the growth of bacteria and mould, causing unsafe spoilage. This can be prevented by removing the plastic wrap and replacing it with greased paper, perforated aluminium foil, or beeswax wraps, which allow moisture to escape. Secondly, fatty acids are released when the casein protein matrix in cheese loosens as it reaches room temperature. The release of fatty acids can be minimised by limiting the cheese's exposure to heat before serving and storing it properly.
Cheese sweats due to condensation when it releases water vapour. This can occur when cheese is left out at room temperature or stored in the refrigerator, especially if it is still wrapped in plastic. Condensation can lead to the growth of unwanted bacteria and mould, causing the cheese to spoil and become unsafe for consumption. To prevent condensation, it is recommended to store cheese properly by using greased paper, perforated aluminium foil, or beeswax wraps, which allow moisture to escape.
Fatty acids are the second main reason why cheese sweats. Cheese is made from milk and contains casein proteins, which loosen up as cheese reaches room temperature, releasing fatty acids. These fatty acids then rise to the surface of the cheese as small droplets of oil. Higher-fat cheeses, such as Gruyère, Comté, and Manchego, are more prone to sweating as they contain more fatty acids. To minimise the release of fatty acids, it is important to limit the cheese's exposure to heat and avoid letting it reach room temperature before serving.
The combination of condensation and fatty acids can result in cheese sweats, affecting the texture, flavour, and overall quality of the cheese. While sweaty cheese is generally safe to consume, it may not be at its peak in terms of flavour and appearance. Proper storage and serving practices can help reduce cheese sweats and preserve the desired characteristics of the cheese.
In summary, cheese sweats are primarily caused by condensation and the release of fatty acids. By understanding the science behind cheese sweats and implementing proper storage and serving techniques, it is possible to minimise condensation and retain the desired fatty acids in the cheese.

Prevent cheese sweating with proper storage
Cheese sweating is mainly caused by fatty acid droplets and condensation. As cheese matures, it releases water vapour. If you keep your cheese wrapped in non-breathable plastic wrap, the water vapour will condense inside the wrap, creating a damp look. To prevent cheese sweating, it is important to store your cheese properly.
Firstly, it is recommended to avoid wrapping your cheese in plastic wrap. Plastic wrap sucks all the moisture out of your cheese, turning it sweaty and, soon, mouldy. It also deprives the cheese of oxygen, which means the flavours have no room to breathe, and the cheese will begin to taste like plastic. Instead, cheese should be wrapped in a breathable material such as parchment paper, baking paper, beeswax wraps, or cheese paper.
If you are using plastic wrap, ensure a clean sheet of wrap is used each time to help prevent mould growth. Glass storage containers with a small vent are another great option for storage as they are airtight, but the small vent lets just the right amount of oxygen in.
For fresh cheeses, it is recommended to store them completely airtight and only for a few days. To keep cheese fresh for longer, you can try the sugar cube hack. This involves double-wrapping your cheese in cheese paper and then storing it in a damp towel-lined plastic container with two sugar cubes, which will regulate the temperature.

People can experience perspiration after eating cheese
It is true that some people experience perspiration after eating cheese. This phenomenon is called "cheese sweats" or, in scientific terms, gustatory sweating or gustatory hyperhidrosis. While it can be caused by a wide range of foods, cheese tends to cause the most powerful reaction. The severity of the cheese sweats is influenced by several factors, including the amount of cheese consumed, individual genetics, and the efficiency of enzymes in the saliva in breaking down food. In rare cases, cheese sweats can be linked to nerve damage in the face or diabetes. However, this condition is uncommon.
Cheese sweats are caused by the release of volatile organic compounds during digestion. Specifically, the casein proteins in cheese loosen up at room temperature, causing the release of fatty acids in the form of tiny drops of oil on the cheese's surface. Additionally, condensation can occur when water vapour is released from the cheese and becomes trapped within its packaging or on its surface. High-fat cheeses, such as hard cheeses and sheep's milk cheeses like Manchego, are more prone to sweating due to their higher fatty acid content.
To prevent cheese sweats, it is recommended to limit the cheese's exposure to heat before serving. This includes removing only the portion of cheese that will be served from the fridge and avoiding leaving it at room temperature for extended periods. For outdoor events, it may be necessary to keep the cheese indoors to prevent sweating. Additionally, serving cheese in larger blocks or bricks delays the onset of sweating since slicing increases the surface area exposed to air.
While sweaty cheese is generally safe to consume, it is not aesthetically pleasing and may indicate a loss of optimal texture and flavour. Removing the cheese from its plastic packaging and wrapping it in greased paper, perforated aluminium foil, or beeswax wraps can help prevent condensation and the growth of unwanted mould. Alternatively, a sugar cube placed in an airtight container with the cheese will absorb excess moisture.

Sweating cheese is not optimal for taste or aesthetics
Sweating cheese is not only unappetising to look at, but it also indicates that the cheese is losing its optimal flavour and texture. While it is still safe to eat, the cheese will not taste as good as it would have without the sweating.
Cheese sweats when it releases moisture into the air, usually when kept at room temperature for too long. This happens due to the presence of fatty acids and water vapour in the cheese. The fatty acids are released as the casein proteins in the cheese loosen up at room temperature. The fatty acids then rise to the surface of the cheese as little drops of oil. The water vapour is released as the cheese matures, and if the cheese is wrapped in plastic, the vapour will condense inside the wrap and create a damp look.
High-fat cheeses, such as cheddar, Swiss, and sheep's milk cheeses like Manchego, are especially prone to sweating. However, any type of cheese can sweat if kept at warm temperatures. To prevent cheese from sweating, it should be kept in the fridge and only removed an hour or so before serving. It should also be kept wrapped, but not in plastic, as this traps moisture and causes condensation. Instead, cheese should be wrapped in greased paper or aluminium foil, which allows moisture to escape.
If the cheese has already started sweating, there is no way to stop the process. However, the sweat can be blotted with a paper towel to improve the appearance of the cheese.
