Mozzarella is a popular cheese with a high moisture content, which means it can spoil faster than other cheeses if not stored properly. To determine if mozzarella cheese is still good, it is important to consider factors such as the 'best before' date, smell, texture, and any signs of spoilage. Aged or drier varieties may exhibit visible mould on the exterior, while pre-grated mozzarella may have a sour or yeasty smell. If you plan on cooking or melting the cheese, it is generally safe to do so even if it has a slight tang, but use your senses and intuition to determine if it has gone bad. Proper storage methods, such as airtight containers and refrigeration, can also help extend the shelf life of mozzarella cheese.

What You'll Learn
Check for smell, texture, and any signs of spoilage
Mozzarella is a soft, high-moisture cheese, which means it can spoil faster if not properly stored. Therefore, it is crucial to store it properly to maximize its shelf life. Fresh mozzarella cheese has a shorter shelf life, while low-moisture mozzarella lasts longer and can be stored for an extended period.
When checking if mozzarella cheese is still good, one of the key things to look for is any change in smell, texture, and any signs of spoilage. If the cheese has developed a sour or yeasty smell, or an excessively cloudy appearance, it is likely spoiled. Aged or drier varieties may also exhibit visible mold on the exterior, which can be cut off if the remaining cheese looks and smells fine. However, if there is any doubt, it is best to discard the cheese to avoid the risk of food poisoning.
It is important to note that proper storage can help extend the shelf life of mozzarella cheese. This includes keeping the cheese sealed, chilled, and immersed in its liquid, such as lightly salted water, if applicable. Pre-shredded mozzarella can be stored in an airtight bag, while fresh mozzarella can be wrapped tightly in plastic wrap or parchment paper to maintain freshness.
Additionally, it is recommended to follow general guidelines for proper storage, such as always storing mozzarella in the fridge and never leaving it out at room temperature for more than two hours. Checking the expiration date and using the cheese before it expires will also help ensure its quality and reduce the risk of spoilage.
While some people may choose to consume mozzarella cheese past its expiration date, especially if it looks and smells fine, it is important to use your senses and intuition. If the cheese has an unusual taste or smell, it is best to discard it. Proper storage and regular checks for spoilage will help ensure that your mozzarella cheese remains safe and delicious for consumption.

Consider the best-before date
The best-before date is a useful indicator of a food product's quality and safety. While mozzarella can be consumed past its best-before date, it is important to consider the potential risks associated with consuming expired food products.
Mozzarella, a high-moisture cheese, has a shorter shelf life compared to aged hard cheeses. Proper storage is crucial to maintaining its freshness and delaying spoilage. It should always be refrigerated and kept chilled, with an optimal storage temperature of below 40°F. To prevent moisture loss and the growth of bacteria, mozzarella should be stored in airtight containers or wrapped tightly in plastic wrap or parchment paper.
The best-before date assumes that the cheese has been stored properly. If your mozzarella has been stored correctly and is only slightly past its best-before date, it may still be safe to consume. However, it is essential to thoroughly inspect the cheese for any signs of spoilage.
When considering whether to consume mozzarella past its best-before date, always trust your senses. Examine the cheese for any visible mold, especially on drier varieties. While mold can be cut off from harder cheeses, softer cheeses like mozzarella should be discarded if mold is present. Additionally, be cautious of any changes in texture, such as a dry or cracked appearance.
Smell is another crucial indicator of freshness. Aged or drier varieties may exhibit a sour or yeasty smell. Brined varieties may have a musty or sour odour, similar to smelly feet, or an excessively cloudy brine. If the cheese has an unpleasant or strong odour, it is best to discard it.
It is important to note that consuming expired food products, including cheese, carries a higher risk of foodborne illnesses. While proper storage can delay spoilage, it does not eliminate the risk of bacterial growth. If you are unsure or concerned about the potential risks, it is always safest to discard the mozzarella and opt for a fresh product.

Look for mould
Mozzarella is a high-moisture cheese, which means it can spoil faster if not properly stored. Therefore, it is crucial to store it properly to maximize its shelf life.
When it comes to determining whether your mozzarella cheese is still good, one of the key things to look for is mould. Mould can indicate that the cheese is no longer safe to consume. Aged or drier varieties of mozzarella may exhibit visible mould on the exterior. If you see mould on a drier variety, you can cut it off and use the remaining cheese as long as it doesn't smell. However, it's important to exercise caution, as mould can be dangerous.
Pre-grated mozzarella can also show visible mould. Additionally, it may have a sour or yeasty smell, indicating spoilage. If you notice any mould or an unpleasant odour, it's best to discard the cheese.
Brined varieties of mozzarella may have a musty, sour, or unpleasant odour. If the brine appears excessively cloudy, it could be another sign of spoilage. In such cases, it is advisable to discard the cheese rather than risk potential food poisoning.
While mould may be more noticeable on drier varieties, it can also occur in moist cheeses like mozzarella. These cheeses can harbour harmful bacteria such as Listeria, E. coli, brucella, and salmonella. Therefore, if you notice any signs of mould or suspect spoilage, it's best to err on the side of caution and discard the cheese.
It's important to trust your senses and intuition when assessing the freshness of mozzarella cheese. If it looks, smells, or tastes off, it's best to discard it rather than risk potential foodborne illnesses. Proper storage, including refrigeration, airtight containers, and adhering to expiration dates, is essential to maintaining the quality and safety of mozzarella cheese.

Store mozzarella properly to maximise its shelf life
Mozzarella is a soft cheese with a high moisture content, which means it can spoil faster if not stored properly. Fresh mozzarella is best consumed on the same day it's purchased, but if you want to keep it for a few days, there are several storage methods you can use to maximise its shelf life.
Firstly, it is important to note that mozzarella should always be stored in the refrigerator. The ideal spot is the crisper drawer of your fridge, as it has a different humidity level that helps keep the cheese from drying out. If your fridge doesn't have a crisper drawer, opt for the middle shelf. Keep your fridge temperature between 34 and 40 °F (1 and 4 °C).
When storing fresh mozzarella, it is crucial to keep it immersed in liquid. Fresh mozzarella is typically packaged in water or brine (a mixture of water and salt). To store leftovers, replicate the liquid in which your cheese came. If your mozzarella came in salted water and you store it in plain water, the cheese will lose some of its salt content, altering the taste. Therefore, always try to use the same liquid as indicated on the ingredient list or packaging.
If you don't want to store your mozzarella in liquid, you can wrap it in cheese, parchment, or wax paper and then place it in a plastic bag or airtight container. However, avoid tightly wrapping mozzarella in plastic wrap as it needs to breathe. Additionally, keep an eye on the moisture level of your cheese, adding a small amount of water if needed.
For shredded mozzarella, simply seal it in its original packaging after opening. Shredded mozzarella usually has a longer shelf life than fresh mozzarella due to its lower water content.
While freezing mozzarella is an option, it is generally not recommended for fresh mozzarella as it significantly alters the texture and flavour. If you choose to freeze mozzarella, cut it into desired portions, wrap each piece in aluminium foil or plastic wrap, and place it in a freezer bag. Frozen mozzarella will keep for up to four months but will have a crumbly texture instead of the desired smooth and creamy consistency.

Taste it
Taste is one of the best tools to determine whether mozzarella cheese has gone bad. While smell is also a good indicator, it is not always reliable, especially for those with a blocked nose or sinus issues.
Mozzarella is known for its mild, creamy flavour and elastic texture when melted. It is considered a healthy option among dairy products due to its low-fat content and high protein. However, it is a high-moisture cheese, which means it can spoil faster if not properly stored.
When tasting mozzarella cheese to determine if it is still good, pay attention to the following:
- Acidic notes: Good mozzarella should have a slight acidity, similar to buttermilk or a fine beer. If the cheese tastes excessively acidic, bitter, or sour, it has likely gone bad.
- Sweetness: A good mozzarella will have a pleasant sweetness that is balanced by its slight acidity. If the cheese tastes overly sweet or savoury, it may be a sign of spoilage.
- Texture: Mozzarella should be crisp, elastic, moist, and soluble. If the cheese has a soft, pudding-like consistency or leaves a fatty residue in the mouth, it is likely not fresh.
- Aftertaste: After chewing and exhaling through the nose, a good mozzarella should leave a buttery and herbaceous aftertaste, with hints of acidity. A pleasant aftertaste is a sign of a good-quality mozzarella.
- Pleasurability: Ultimately, the taste of a good mozzarella should bring pleasure and inspire positive sensations, memories, or culinary ideas. If the cheese tastes unpleasant or induces negative sensations, it is likely not fresh or has gone bad.
It is important to note that even if the mozzarella tastes slightly off, it may still be safe to consume, especially if it is cooked or melted. However, if there are significant signs of spoilage, such as a strong sour or yeasty smell, visible mould, or a musty odour, it is best to discard the cheese to avoid the risk of food poisoning.
