Fresh mozzarella is mild-smelling, so a strong odour is a sign of spoilage
Mozzarella is a soft cheese made from cow's milk or water buffalo milk. It is a popular cheese of Italian origin and is used in a variety of dishes, including pizza, calzone, baked ziti, and pasta. As a soft cheese, mozzarella tends to spoil more quickly than hard cheeses, and it typically lasts about two weeks in the refrigerator and six months past its expiration date when frozen. Fresh mozzarella, in particular, has a milder scent compared to other cheeses, and its shelf life is influenced by various factors, such as storage practices and the original packaging.
When it comes to determining if your mozzarella has gone bad, your senses of sight, smell, and taste can be your best tools. Firstly, inspect the cheese for any signs of mould, which is a clear indication that the cheese is no longer edible. Most mould on cheese will be green or blue and easily visible against the off-white colour of the mozzarella. If you notice any mould, discard the entire block of cheese, as consuming spoiled cheese can be hazardous to your health.
In addition to mould, a strong or sour odour is another sign of spoilage. Fresh mozzarella typically has a mild aroma, so if it starts to smell sour or "off" in any way, it's best to throw it out. This sour smell is indicative of old mozzarella, and while it may not cause any stomach aches, the taste will be unpleasant. Trust your sense of smell, and if something seems off, it's better to be safe and discard the cheese.
If your mozzarella passes the smell test, you can also perform a taste test by cutting off a small piece and sampling it. If the cheese has a sharp, sour, or unfamiliar taste, it has likely gone bad, and you should discard it. While tasting a tiny amount of old mozzarella may not make you sick, it is essential to trust your taste buds and avoid consuming anything that doesn't taste right.
To extend the shelf life of your mozzarella, proper storage is crucial. Always keep it refrigerated, and if it comes in liquid, you can store it in that liquid to help maintain its freshness. Otherwise, wrap it tightly in plastic wrap or cheese wrap to prevent it from drying out and hardening. Additionally, store it away from other foods with strong odours, as mozzarella can absorb flavours and odours from its surroundings.

If it smells like sour milk, it's gone bad
Mozzarella is a soft cheese made from cow's milk or, traditionally, the milk of water buffalo. It is a popular cheese of Italian origin, used in dishes such as pizza, calzone, and baked ziti. Soft cheeses tend to spoil more quickly than hard cheeses, so it is important to know how to tell if mozzarella has gone bad.
If your mozzarella smells like sour milk, it has gone bad and should be discarded. While eating small amounts of spoiled mozzarella is unlikely to make you sick, it is still unpleasant and could be hazardous to your health. The bacteria and mold that form on soft cheeses may or may not be toxic to humans, so it is better to be safe and avoid any possible problems.
Mozzarella has a light, mild aroma, so an off smell is a clear sign that the cheese has gone bad. In addition to smelling the cheese, you can also look for signs of spoilage. Mold, hardening, or dryness around the edges are all indications that the cheese is no longer good to eat. If stored incorrectly or for too long, mozzarella can begin to dry out and harden. While mold can be trimmed from some hard cheeses, it is not safe to do so with mozzarella, and the entire block should be discarded.
To extend the shelf life of mozzarella, it is important to store it properly. Mozzarella should always be kept refrigerated, and it should be wrapped tightly to prevent it from drying out and absorbing flavors and odors from other foods. It should also be stored away from meat to prevent possible contamination. Large chunks of mozzarella will keep longer than small pieces or slices, which generally begin to lose quality after a month or less.

If it's spoiled, it may have a sharpness or unfamiliar taste
Smell is one of the best ways to determine whether mozzarella cheese is spoiled and unsafe to eat. If you detect the telltale odour of sour milk, the cheese is no longer good to eat. However, sometimes the cheese can be spoiled without an obvious smell, and this is where tasting becomes important. If you are still uncertain about its edibility, use a sharp knife to cut away a small piece and sample it. If the mozzarella has developed a sharpness, sourness, unfamiliar taste, or bitterness, it has gone bad and should be discarded. Spoiled cheese may also exhibit a highly acidic taste, with an overgrowth of bacteria leading to excessive fermentation and a strong, sour taste.
Mozzarella is a soft cheese, and these tend to spoil more quickly than hard cheeses. It is also a moist cheese, and therefore can harbour dangerous bacteria such as Listeria, E. coli, brucella, and salmonella. If you are in doubt, it is always best to throw the cheese away.
To prevent mozzarella cheese from spoiling, it should be stored in the refrigerator at around 4-5 degrees Celsius (39-41 degrees Fahrenheit). It should be tightly wrapped to prevent exposure to the air, which can cause it to dry out or become contaminated.

It should be tightly wrapped in the fridge to prevent it from drying out and to stop it from absorbing other food odours
Mozzarella is a soft cheese, usually made from cow's milk, and is a popular ingredient in dishes like pizza, calzone, and pasta. Soft cheeses tend to spoil more quickly than hard cheeses, and mozzarella is no exception. It has a mild aroma, and any strong, sour, or "off" smell indicates that the cheese has gone bad and should be discarded.
To prevent spoilage, it is important to store mozzarella cheese properly. This involves keeping it tightly wrapped when stored in the refrigerator. The cheese naturally absorbs flavours and odours from other foods, so a tight wrap will help to maintain its mild aroma and prevent it from taking on undesirable smells.
The wrapping also serves to prevent moisture loss and slow down the drying process. If mozzarella cheese dries out, it becomes hard, which affects its quality and texture. While hardened mozzarella can still be melted and used in certain recipes, it is not ideal for all applications and is generally considered inferior in quality.
To summarise, tightly wrapping mozzarella cheese in the fridge serves two main purposes: it helps to maintain the cheese's moisture content and slow down drying, and it prevents the absorption of unwanted food odours, thus preserving the cheese's mild aroma and overall quality.

It's traditionally made from water buffalo milk, but most mozzarella today is made from cow's milk
Mozzarella is a soft cheese with a light, mild aroma. It is typically made from cow's milk, but it can also be made from water buffalo milk, particularly in Italy, where the cheese originated. The water buffalo milk variety, known as "mozzarella di bufala" or "muzzarella 'e vufera" in Italy, has a stronger, tangier, almost sour taste compared to the milder, sweeter flavour of cow's milk mozzarella. The texture of water buffalo milk mozzarella is softer, less firm, and more moist, with a slightly spongy feel. It is also brighter white in colour.
Mozzarella made from cow's milk is the more common variety found in stores and is often produced in countries like the United States, where it is easier to source cow's milk. This type of mozzarella is often described as less tasty or flavourful compared to its water buffalo counterpart. However, some people prefer the milder flavour of cow's milk mozzarella, especially when served by itself or with certain dishes.
The production of mozzarella from water buffalo milk has a long history in Italy, dating back to the beginning of the 12th century. It became widespread in southern Italy during the second half of the 18th century. Today, it is still traditionally manufactured in specific regions of Italy, such as Campania, Lazio, Apulia, and Molise. The Italian government officially recognises this variety as "mozzarella di latte di bufala" to distinguish it from cow's milk mozzarella.
Water buffalo milk contains higher levels of solids, resulting in higher percentages of protein, fat, and minerals compared to cow's milk. This difference in composition gives water buffalo milk mozzarella its distinct taste and texture. The milk is produced by Italian Mediterranean buffalo, which account for approximately 30% of the total dairy buffalo population worldwide.
While cow's milk mozzarella is more readily available and may be preferred by those who enjoy a milder flavour, water buffalo milk mozzarella is sought after for its stronger taste and softer texture. It is often considered a more premium product and is used in various dishes, such as calzone, salads, pizza, and grilled bread.
