In the culinary world, cheese holds a special place due to its intricate and delicate nature. One of the key aspects of cheese that enhances its flavor is the aging process, where a combination of humidity, temperature, and time work together to give each cheese its distinct characteristics. For restaurants that pride themselves in offering an array of aged cheeses, maintaining the right conditions in their cheese aging rooms, also known as cheese cellars or caves, is of utmost importance. In this article, we will discuss the fundamental aspects of temperature and humidity control for aging cheese in a restaurant setting.
Before we delve into humidity and temperature control specifics, it is crucial to understand why these factors are so significant in the cheese aging process. Aging cheese is not merely a matter of letting the cheese sit and mature over time. It is an intricate process that needs constant monitoring and control, much like aging fine wine or curing meats.

The aging process allows for the development of the cheese’s flavor and texture. The microbiota and enzymes present in cheese act on the proteins and fats, resulting in the development of the characteristic aroma, flavor, and texture. However, this process is highly dependent on the environment the cheese is aged in, especially the temperature and humidity.
The temperature in a cheese aging room or cellar controls the activity of the molds and bacteria that contribute to the cheese's flavor. It significantly influences the rate of moisture loss, the development of the rind, and the overall aging process. The ideal temperature for aging cheese is usually between 50 to 55 degrees Fahrenheit (10-12 degrees Celsius). This range will keep the bacteria alive but slow down their activity, allowing the cheese to age at a controlled pace.

However, the specific temperature can vary based on the type of cheese. For instance, blue cheeses require a slightly higher temperature to encourage the growth of the particular mold, Penicillium roqueforti, that gives them their distinctive flavor.
To maintain the desired temperature in a cheese aging room, it is essential to have a reliable and adjustable cooling system. This system should be able to maintain a stable temperature, even during warmer months, and should be adjustable to cater to different types of cheeses.
Next to temperature, humidity is the second most critical factor in aging cheese. Humidity controls the rate at which a cheese loses moisture. If the air in the aging room is too dry, the cheese will lose moisture rapidly, resulting in a hard, dry cheese. Conversely, if the air is too moist, the cheese will not lose enough moisture, leading to a soft, possibly spoiled cheese.
The target humidity level for most aging cheeses falls within 80 to 95 percent. Again, this range can vary depending on the type of cheese. For example, hard cheeses such as Parmesan need lower humidity (around 80 percent), while soft cheeses like Camembert require a higher humidity level (close to 95 percent).
To control humidity in a cheese aging room, you may need to invest in a humidifier or a dehumidifier, depending on the external conditions. It is also essential to monitor the room's humidity level regularly to ensure it remains within the desired range.
While temperature and humidity are the main factors, they are not the only ones to consider. Air flow and fresh air exchange are also crucial in a cheese aging room.
Air flow helps to ensure even temperature and humidity throughout the room and to prevent mold and bacteria from growing excessively in certain areas. It also helps in removing the buildup of certain gases that can affect the cheese's flavor.
On the other hand, fresh air exchange is necessary to introduce new, clean air into the aging room, which helps to maintain a healthy, balanced microbial population.
The design and maintenance of the cheese aging room can also affect the temperature, humidity, and air exchange. For instance, a room with good insulation will maintain a stable temperature and humidity level more efficiently. Similarly, the materials used in the room, such as wood or stone, can impact the moisture levels.
Regular cleaning and maintenance of the aging room and its equipment are essential to prevent mold contamination and to ensure optimal conditions for aging. This is particularly important for the cooling system and the humidifier or dehumidifier, as dust and mold buildup can affect their efficiency.
In conclusion, temperature and humidity control is a complex but critical aspect of cheese aging. By understanding and managing these factors, restaurants can offer a wide variety of aged cheeses, each with its unique and delicious flavor.
In addition to the control of temperature and humidity, the storage techniques used in a cheese aging room also play a significant role in the quality of the aged cheese. The type of cheese, its stage in the aging process and the desired end result all influence how cheese should be stored.
First off, the placement of cheese in the aging room matters. Cheese should not be placed directly on the floor or too close to the cooling system as it can affect the cheese's temperature and could lead to uneven aging. Likewise, cheese should not be positioned too close to each other to prevent cross-contamination and to allow for proper air circulation.
The way the cheese is wrapped also holds significance. The traditional method involves wrapping cheese in cheese paper, wax paper or parchment paper. These materials help maintain the right level of moisture while still allowing the cheese to breathe. Plastic wrap, on the other hand, can cause the cheese to sweat and alter its flavor. However, waxed rinds, cloth-bound wheels or natural molds require neither paper nor plastic, they simply need the right temperature and humidity conditions to develop.
Shelf life or the length of the aging process varies according to the type of cheese. Fresh cheese like mozzarella requires minimal aging, typically a matter of days. Hard cheeses like Parmesan, on the other hand, can be aged for months to years, enhancing their flavors over time.
Lastly, don’t forget that the aging process doesn't stop once the cheese leaves the cheese cave. Storing cheese properly even after aging can help preserve its flavor and texture. This involves keeping it in a cool place, ideally a refrigerator set to around 35 to 40 degrees Fahrenheit (1 to 4 degrees Celsius), and rewrapping it in fresh paper after each use.
Creating the perfect cheese aging room in a restaurant setting involves striking a fine balance between several factors. It is not just about maintaining the right temperature and humidity but also ensuring proper air flow, incorporating effective cheese storage techniques, and regularly cleaning and maintaining the room and its equipment.
Each aspect plays a crucial role in the cheese making process, influencing the growth and activity of microbiota and enzymes and ultimately determining the quality, flavor, and texture of the aged cheese. By understanding these factors, restaurants can effectively control the aging process to produce an array of high-quality cheeses, each with its unique characteristics and shelf life, that cater to the varying tastes of their customers.
From the type of cheese to the conditions in the cheese cave, every detail matters. By dedicating the time and attention to these factors, restaurants can ensure that their cheese will not only have a longer shelf life, but will also be a high-quality product that enhances the dining experience for their patrons.
In conclusion, by investing in a well-designed cheese aging room and adhering to temperature, humidity and storage guidelines, restaurants can perfect the art of aging cheese. The end result? A selection of delectable cheeses that can impress even the most discerning cheese connoisseur.
