Parmesan cheese is a hard, aged cheese with a distinctly sharp flavour. It is traditionally made from cow's milk and aged for at least 12 months, during which time bacteria break down lactose and contribute to flavour development through the production of by-products. Harder cheeses like Parmesan have lower moisture content, which inhibits bacterial growth and allows them to be stored safely without refrigeration for longer periods. This process of maturation and flavour development through bacterial action classifies Parmesan as a ripened cheese.

What You'll Learn
Parmesan is a hard, ripened cheese
The ripening process for Parmesan involves the use of bacteria, which break down the lactose in the cheese. This breakdown of lactose by bacteria produces a slightly acidic byproduct, which impacts the flavour of the cheese. Additionally, some bacteria cut protein chains to certain lengths, and these protein chains have very distinct flavours.
The texture of Parmesan, which is hard and sharp, makes it a popular cheese to grate or shave and sprinkle on top of salads, pasta dishes, and even grilled cheese sandwiches. It can also be formed into chisels and combined with nuts for a snack similar to trail mix.
As a hard cheese, Parmesan does not require refrigeration. However, once opened, it is best to refrigerate or freeze Parmesan to extend its longevity. Properly stored, Parmesan can last up to about six weeks in the refrigerator and even longer if the package is not opened.

Parmesan is low in lactose
Parmesan cheese is traditionally made from cow's milk and is aged for at least 12 months. During the ageing process, the lactose in the cheese is broken down by bacteria, which means that Parmesan has pretty low lactose levels compared to some similar cheeses. This makes it a good option for those who are lactose intolerant, as it can be eaten in moderation.
However, it's important to note that while Parmesan is low in lactose, it is not completely lactose-free. Those with lactose intolerance may still experience symptoms if they consume too much Parmesan. It is always important to know your limits and stick to them when it comes to food intolerances. Keeping a food diary can be a helpful way to understand your limits and manage your diet.
The ageing process of cheese not only reduces lactose levels but also impacts flavour, meltability, and hardness. As cheese ages, its flavour becomes stronger, and its texture becomes harder. This is why Parmesan has a distinctively sharp taste and hard texture.
In addition to being low in lactose, Parmesan is also a good source of calcium and other nutrients. Aged cheese tends to have higher levels of fat, protein, retinol, B12, zinc, calcium, magnesium, and other nutrients compared to younger cheese. This makes Parmesan a nutrient-dense option, especially for those who are lactose intolerant and may struggle to get enough calcium in their diet.
It's worth noting that some people with lactose intolerance may experience symptoms from consuming Parmesan due to the presence of whey, which is added during the cheese-making process. Whey is a protein found in dairy that can cause similar symptoms to lactose intolerance in some individuals. Therefore, it is important for those with lactose intolerance to understand their specific triggers and tolerances to manage their diet effectively.

Parmesan can be stored without refrigeration
Parmesan cheese is a hard cheese with a low moisture content, which means it can be stored for long periods without refrigeration. In fact, if stored properly, Parmesan cheese has a long shelf life. However, once the package is opened, it is best to refrigerate or freeze the cheese to extend its longevity.
When it comes to storing Parmesan cheese, there are a few things to keep in mind. Firstly, if you choose to keep it out of the fridge, plan on using it within three to seven days. Secondly, the cheese should be stored in an airtight container or bag to prevent oxidation, which can affect its flavour and texture.
If you do decide to refrigerate your Parmesan cheese, it is important to avoid the cheese drawer, as this is usually located close to the refrigeration vents, which can dry out the cheese. Instead, store it in the crisper drawer. Additionally, for the best flavour, let the cheese come to room temperature before serving.
A whole, unopened block of Parmesan cheese can last seven to nine months in the refrigerator, while an opened block will last one to two months. Grated Parmesan cheese, on the other hand, will only last about one week in the refrigerator.
In conclusion, while Parmesan cheese can be stored without refrigeration, doing so will reduce its shelf life. For optimal flavour and texture, it is recommended to store Parmesan cheese in an airtight container in the refrigerator, preferably in the crisper drawer.

Parmesan is made from cow's milk
Parmesan cheese is made from cow's milk and is aged for at least 12 months. In the production of Parmesan, whole milk and naturally skimmed milk are combined and then distributed into copper vats for heating. During the two-step heating process, additional ingredients like whey and rennet, a natural enzyme found in the stomach of young mammals, are added to form the curd. The longer the cheese ages, the more lactose is processed by bacteria, resulting in a stronger taste and ideal texture. This also reduces the moisture content, making the cheese denser and more nutritious.
The traditional Italian Parmesan cheese, known as Parmigiano-Reggiano, is made from unpasteurized cow's milk. It is produced in specific regions of Italy, including Parma, Reggio Emilia, Modena, Bologna, and Mantova. The strict geographic origin and production methods of Parmigiano-Reggiano are legally protected within the European Union, where the term Parmesan may only refer to this specific variety.
Outside of the European Union, the term "Parmesan" is used more generically for locally produced imitations of Italian Parmesan. These cheeses are also typically made from cow's milk but may have different aging requirements and production standards. For example, in the United States, "Parmesan" must be made from cow's milk, cured for at least 10 months, and meet certain moisture and fat level regulations. However, some American manufacturers have been investigated for exceeding allowed limits of anticaking agents in their grated "Parmesan" products.
The use of cow's milk in Parmesan production is an important distinction from other similar cheeses, such as Pecorino Romano, which is made from sheep's milk and has a stronger and saltier flavour profile. The type of milk used and the aging process significantly impact the taste, texture, and nutritional content of the resulting cheese.
Overall, Parmesan cheese is known for its distinctive granular texture and nutty flavour, which make it a versatile ingredient in a variety of dishes, from pasta to salads. Its low lactose levels and sharpness elevate the taste experience, making it a popular choice for food enthusiasts worldwide.

Parmesan is aged for at least 12 months
Parmesan cheese is a hard, aged cheese with a low lactose content. It is traditionally made from cow's milk and is aged for a minimum of 12 months, with some varieties aged for longer. For example, Cello Copper Kettle Parmesan is aged for 16 months in copper vats, creating a sweet flavour through the natural fermentation of the milk.
The process of ageing Parmesan involves a two-step heating process, during which additional ingredients like whey and rennet are added to form the curd. The longer ageing process reduces the moisture content of the cheese, making it harder and less perishable. This means that hard cheeses like Parmesan can be stored for longer periods without refrigeration compared to softer cheeses.
The ageing process also affects the flavour of the cheese. As the cheese ages, bacteria break down the lactose, causing a change in flavour. Different bacteria thrive at different stages of ageing, further influencing the taste. The longer ageing process of Parmesan contributes to its distinct, sharp flavour.
In addition to its flavour, the ageing process also impacts the texture of Parmesan. The low moisture content resulting from ageing makes Parmesan a hard cheese. This hard texture makes it ideal for grating or shaving, and it is commonly used as a topping for pasta, salads, or snacks like trail mix.
The ageing process also contributes to the nutritional profile of Parmesan. Aged cheeses like Parmesan have higher levels of fat, proteins, retinol, B12, zinc, calcium, and magnesium compared to younger cheeses. This makes Parmesan a denser source of nutrients.
In summary, the ageing process of Parmesan cheese for at least 12 months is crucial in developing its characteristic flavour, texture, and nutritional profile. The longer ageing process transforms the cheese, making it a versatile and flavourful ingredient in various dishes.
