Mozzarella is a soft cheese that is highly perishable and has a short shelf life. Proper storage is essential to maintaining its freshness and preventing spoilage. Unopened mozzarella cheese stored in the refrigerator can last for a few weeks to a couple of months past the Best By date, depending on the packaging and temperature. Vacuum-sealed mozzarella can last up to 3-4 weeks, while shredded mozzarella can last about a week after the Sell By or Best By date. Freezing mozzarella can extend its shelf life, but it may affect the texture. It's important to regularly check for signs of spoilage, such as mold, off odor, or changes in texture, before consuming mozzarella cheese.
| Characteristics | Values |
|---|---|
| Packaging | Unopened mozzarella should be stored in its original packaging until ready to use. |
| Storage Temperature | Keep mozzarella in the coldest part of the refrigerator, typically the back, where the temperature is more stable. |
| Avoid Cross-Contamination | Store mozzarella away from foods with strong odors or potential contaminants to prevent any transfer of flavors or bacteria. |
| Shelf Life | Unopened mozzarella can last for about 1 week after the "Sell By" or "Best By" date on the package. Vacuum-sealed mozzarella can last several weeks in the fridge unopened—up to 3 to 4 weeks past the packing date. |
| Freezing | Fresh mozzarella can be frozen but may lose its creamy texture. Frozen mozzarella can be safe indefinitely. |

What You'll Learn
Vacuum-sealed mozzarella can last 3-4 weeks unopened
Properly storing mozzarella cheese is essential to maintaining its freshness and preventing spoilage. Unopened mozzarella cheese has specific storage requirements that should be followed to maximize its shelf life.
To maintain the quality of unopened mozzarella cheese, it should be stored in its original packaging until you are ready to use it. Keep the cheese in a cool, dry place within the refrigerator, ideally in the cheese or dairy compartment. This helps to maintain a consistent temperature and humidity level, which is crucial for preserving the cheese's texture and flavor.
Once opened, transfer the cheese to an airtight container or cover it with plastic wrap to keep it fresh. It can be stored in its liquid (if packed in water) or submerged in cold water in a container for up to 5 days for best results. Freezing is an option, but fresh mozzarella can lose its creamy texture.
Determining whether your unopened mozzarella cheese has gone bad requires careful observation. Spoiled mozzarella can pose health risks, so it's important to be aware of the signs of spoilage. Look for mold growth, an off smell, or a slimy texture.

Fresh mozzarella without brine dries out faster
Fresh mozzarella is typically stored in water and sold in balls or blocks. It is a high-moisture cheese, which means it can spoil faster if not stored properly. The traditional version, Mozzarella di Bufala, is made from the milk of water buffalo and is considered a delicacy with a distinctively rich and creamy flavour. Today, mozzarella is also made from cow's milk and has become a staple in many Italian dishes and world cuisines.
If you have discarded the brine, you can try storing the mozzarella in lightly salted water to help extend its shelf life by a few days. The salt in the water helps to draw out excess moisture from the cheese, slowing down the drying process. Alternatively, you can wrap the cheese in moistened paper towels and then in plastic wrap to help retain moisture.
Another option is to shred the mozzarella and place it on a paper towel in a warm oven (110-120°F) to dry it out slightly. This can be done in advance and stored in the refrigerator. However, this method may alter the quality of the mozzarella, so it is important to consider the intended use of the cheese.
Proper storage of fresh mozzarella is crucial to maintaining its quality and extending its shelf life. When stored unopened in its original vacuum-sealed packaging in the refrigerator, fresh mozzarella can last for several weeks, up to 3-4 weeks past the packing date. Once opened, it should be stored in an airtight container or wrapped in plastic wrap and kept in its liquid or submerged in cold water for up to 5 days.

Store mozzarella in its original packaging
Storing mozzarella cheese correctly is crucial for maximising its shelf life. If you've bought unopened mozzarella cheese in its vacuum-sealed package, it's best to keep it in the fridge until you're ready to use it. The packaging is designed to protect the cheese from moisture and contaminants.
The cheese should be kept in a cool, dry place within the refrigerator, ideally in the cheese or dairy compartment. This helps to maintain a consistent temperature and humidity level, which is crucial for preserving the cheese's texture and flavour. The low temperatures slow down bacterial growth and enzymatic activity, preventing spoilage. It's important to keep the cheese at a temperature between 32-40°F (0-4°C) to ensure its longevity.
Additionally, it's important to keep the cheese sealed. This helps maintain its moisture and prevents contamination. Keep the cheese in the coldest part of your refrigerator, typically the back, where the temperature is more stable.
It's also essential to avoid cross-contamination. Store mozzarella away from foods with strong odours or potential contaminants to prevent any transfer of flavours or bacteria.
By following these storage guidelines, you can extend the freshness of your unopened mozzarella cheese and enjoy its delicious taste and texture for a longer period.

Refrigeration slows bacterial growth, preserving cheese
Proper storage is essential for maintaining the freshness of mozzarella cheese and preventing spoilage. Unopened mozzarella cheese can be stored in the refrigerator for a few weeks past its packing date. However, it's important to maximize its shelf life by maintaining the right storage conditions.
Refrigeration plays a crucial role in preserving mozzarella cheese. By maintaining temperatures between 32°F and 40°F (0°C and 4°C), the growth of bacteria and enzymes that cause spoilage is slowed down. This temperature range ensures that mozzarella cheese remains safe to consume for a more extended period.
Bacteria thrive and multiply rapidly at temperatures between 40°F and 140°F. Therefore, keeping mozzarella cheese refrigerated helps to preserve it by slowing down bacterial growth. Additionally, proper storage involves keeping the cheese sealed in its original packaging, maintaining a consistent temperature, and storing it away from foods with strong odors or potential contaminants.
Vacuum-sealed packaging further prolongs the shelf life of mozzarella cheese by minimizing exposure to air, moisture, and external contaminants. This packaging method helps maintain the quality and freshness of the cheese by creating a barrier that protects the cheese from spoilage.
By following these refrigeration and storage practices, consumers can effectively slow down bacterial growth and preserve the quality, texture, and flavor of mozzarella cheese. Proper storage ensures that consumers can enjoy their mozzarella cheese for a more extended period while also reducing food waste.

Signs of spoilage: mould, off odour, flavour or appearance
Unopened mozzarella cheese can last for a while, but it's crucial to store it properly to maximise its shelf life. It's important to check for signs of spoilage and follow best storage practices to keep your mozzarella fresh and safe to eat.
Mould growth is a sign of spoilage in mozzarella cheese. If you see any mould, even in small spots, it's best to discard the entire package. The mould can appear as blue, green, or black patches on the surface of the cheese.
Off odour is another indicator of spoilage. If the cheese develops an unpleasant or strange smell, it should be discarded. A slight change in odour can indicate bacterial growth or other spoilage, so it's better to be cautious and throw it out.
Changes in flavour or appearance can also indicate spoilage. If the cheese tastes or looks different from what you would typically expect, it's best to avoid consuming it. Trust your senses and, if something seems off, it's safer to discard the cheese.
Additionally, check for a slimy texture or any signs of degradation, such as the cheese becoming chewy, brittle, or separated. These are signs that the cheese is past its prime and should not be consumed.
Remember, spoiled mozzarella cheese can pose health risks, so it's important to be vigilant about the signs of spoilage and prioritise your safety when in doubt.
