The shelf life of unopened mozzarella cheese is influenced by several factors, including packaging, storage temperature, type of mozzarella, and expiration date. Proper storage is crucial to maximize its longevity. Unopened mozzarella cheese should be kept in its original packaging and stored in a cool, dry place within the refrigerator, ideally in the cheese or dairy compartment. This helps maintain consistent temperature and humidity levels, preserving the cheese's texture and flavor. Refrigeration plays a vital role in slowing down bacterial growth and enzymatic activity, preventing spoilage. The recommended temperature range for storing mozzarella cheese is between 32-40°F (0-4°C).
What You'll Learn
Fresh mozzarella should be eaten on the day it's made, according to connoisseurs
Fresh mozzarella is best enjoyed the day it's made, according to connoisseurs who savour its delicate, milky flavour and soft, creamy texture. These enthusiasts believe that refrigeration compromises the cheese's texture and flavour, making it chewier and more rubbery. They recommend keeping mozzarella at room temperature and consuming it as soon as possible.
However, not everyone adheres to this strict guideline. Some suggest that fresh mozzarella can be refrigerated but should be removed from the fridge one to two hours before serving to allow it to return to room temperature, optimising its mouthfeel, texture, and flavour. Others maintain that it can be safely stored in the refrigerator until ready to eat.
The conflicting advice stems from the fact that refrigeration does alter the characteristics of fresh mozzarella. Food scientist Dave Arnold's experiments support the notion that refrigeration absorbs water into the curd, making the cheese firmer and less milky in flavour. This transformation is undesirable for those who appreciate the unique, delicate qualities of fresh mozzarella.
For those who choose to refrigerate their fresh mozzarella, proper storage is essential. It should be kept in its original packaging or a sealed container to maintain moisture and prevent contamination. The ideal refrigerator temperature for mozzarella is between 34°F and 38°F (1°C to 3°C), and it should be placed in the coldest part of the fridge, typically the back, for the most stable temperature.

Refrigeration is key to preserving mozzarella
Firstly, it's important to understand the role of temperature in preserving mozzarella. Low temperatures in the refrigerator slow down bacterial growth and enzymatic activity, which are primary causes of food spoilage. The ideal temperature range to store mozzarella is between 32°F and 40°F (0°C to 4°C). Maintaining a consistent temperature within this range is crucial for preserving the cheese's texture and flavor. Therefore, it's best to keep mozzarella in the coldest part of the refrigerator, usually the back, to ensure a stable temperature.
Additionally, the placement of mozzarella within the refrigerator matters. Avoid placing the cheese near the refrigerator door, as this area is more susceptible to temperature fluctuations, which can negatively impact the quality of the cheese. Instead, keep mozzarella in the cheese or dairy compartment, as these dedicated compartments are designed to maintain optimal temperature and humidity levels for dairy products.
The packaging of mozzarella also plays a significant role in its preservation. Unopened mozzarella should be stored in its original packaging, which is designed to protect the cheese from moisture and contaminants. Vacuum-sealed packaging helps to prolong the shelf life by minimizing exposure to air and potential contaminants. If the original packaging is damaged, transfer the cheese to an airtight container or resealable plastic bag to prevent air exposure and maintain freshness.
It's worth noting that freezing mozzarella is not recommended, as it can alter the texture and flavor of the cheese. However, if freezing is necessary, ensure the cheese is well-wrapped and consume it within a few months.
By following these refrigeration and storage guidelines, you can effectively preserve unopened mozzarella cheese and maintain its quality, freshness, and safety for a longer period.

The type of mozzarella impacts shelf life
The type of mozzarella cheese you have will impact its shelf life. Fresh mozzarella, for example, has a shorter shelf life than low-moisture, part-skim mozzarella. Fresh mozzarella is typically packaged in brine, whey, or a water/liquid packing solution to help retain its shape, moisture, and soft, creamy, slightly elastic texture.
Expert opinions vary on the shelf life of fresh mozzarella. Some believe it should be eaten on the day it was made and advise against refrigeration, as this affects the texture. Others say it's okay to refrigerate but to remove it from the fridge one to two hours before eating to let it return to room temperature, improving the mouthfeel, texture, and flavor. A third group says it's fine to leave fresh mozzarella refrigerated in its solution until you're ready to eat it.
Vacuum-sealed containers of unopened, refrigerated fresh mozzarella will last up to four to six weeks from the date of manufacture, assuming it's salted. Once opened, it should be refrigerated and consumed within four to seven days. It won't go bad after this time, but it will begin to sour and change in taste.
Traditional aged mozzarella, on the other hand, has a much longer shelf life due to its lower water content and the processing it undergoes during manufacturing. Unopened and refrigerated, it can last up to three weeks beyond the use-by date or up to 70 days after the production date. If unopened and frozen, it can last between four and six months after the use-by date.

You can freeze mozzarella to extend its shelf life
Mozzarella is a versatile cheese used in many dishes, from pizzas to salads. It is a soft cheese made from cow or buffalo milk, and its shelf life depends on its form and whether it has been opened. While freezing is an option to prolong its shelf life, there are some things to consider.
Freezing Mozzarella
Freezing mozzarella is a practical way to extend its shelf life, especially for shredded and block varieties. However, it is important to note that freezing can alter the characteristics of the cheese. Fresh buffalo mozzarella, for example, is not recommended for freezing as it can affect its delicate texture and fresh, milky flavour.
On the other hand, freezing shredded and block mozzarella can be more successful, although it may still experience some texture changes. Block mozzarella can become slightly grainy, but this may be less noticeable when melted in dishes like pizza or lasagna.
Steps to Freeze Mozzarella
To freeze shredded mozzarella, portion it into resealable freezer bags, removing excess air before sealing and freezing flat. For block mozzarella, tightly wrap it in plastic wrap or foil, then place it in a freezer bag or use a vacuum seal.
Thawing Frozen Mozzarella
It is best to thaw frozen mozzarella slowly in the refrigerator overnight or for several hours. Avoid using the microwave or thawing at room temperature, as this can lead to uneven thawing and undesirable texture changes.
Shelf Life of Frozen Mozzarella
The length of time mozzarella can be stored in the freezer depends on the type. Shredded and block mozzarella can be frozen for 3 to 6 months, while fresh mozzarella is best consumed within 1 to 2 months. Properly stored, frozen mozzarella will maintain its best quality for about 6 months but can be safe to consume beyond that period.
Signs of Spoilage
It is important to check frozen mozzarella for any signs of spoilage. Look for freezer burn, which appears as ice crystals or dry, whitish patches. Thawed mozzarella should not feel overly mushy, crumbly, or rubbery compared to its fresh state. Be cautious if you notice any off odours or flavours, such as a sour smell or unusual taste, as these may indicate spoilage.
