Feta cheese is stored in brine to keep it fresh
Feta cheese is a soft, white, Greek cheese made from sheep's milk or a mixture of sheep and goat's milk. It is a staple in many kitchens and is used in a variety of dishes, from appetizers to desserts. However, feta cheese can go bad if not stored properly, developing an overly sour or bitter taste and a rubbery texture.
To prevent this, feta cheese is often stored in brine, a solution of water and salt. The brine helps to preserve the cheese, keeping it moist and fresh for longer. It also adds a salty flavour to the cheese. When purchasing feta cheese from a supermarket, it is typically sold in sealed packages with a small amount of brine. This brine helps to extend the shelf life of the cheese, but once the package is opened, the cheese is exposed to air and can dry out and lose flavour.
To keep feta cheese fresh for longer, it is recommended to make your own brine by dissolving kosher salt in water and storing the cheese in this solution. This can be done by completely submerging the cheese in the brine and sealing it in an airtight container in the refrigerator. This method can keep feta cheese fresh for up to three months. Additionally, when the brine level gets low, it can be topped off with filtered water and salt to maintain the correct level.
Another option for storing feta cheese is to use a milk bath, which will reduce the saltiness and create a creamier texture. However, this method does not preserve the cheese for as long as brine, and it is recommended to only soak the cheese in milk for a couple of hours before use. Overall, storing feta cheese in brine is the best way to keep it fresh and flavourful for extended periods.

Feta cheese is a beloved food enjoyed worldwide and used in various dishes, such as salads, sandwiches, pasta, or even eaten alone with crackers. It is a soft, white, brined cheese with a tangy and salty flavour, originally from Greece. It is typically made from sheep's milk or a combination of sheep's and goat's milk.
Feta cheese is a unique cheese that requires specific handling and storage to maintain its distinctive flavour and texture. Proper storage is essential, as improper storage can cause the cheese to go bad before it can be enjoyed. Feta cheese is typically sold in a brine solution, which helps preserve its freshness and keeps it moist. However, once opened, it is recommended to consume the cheese within one to two weeks for maximum deliciousness, even though it may last up to six months unopened.
To extend the shelf life of feta cheese and maintain its quality, it is crucial to follow some expert storage tips. Kathleen Serino, a cheese expert, recommends that if the brine solution decreases, it can be topped off with filtered water and salt. Dissolving two teaspoons of kosher salt in one to two cups of water can create a brine solution. The concentration of salt in the water can be adjusted to achieve the desired saltiness for the cheese. Subsequently, the feta cheese should be completely submerged in this brine solution and stored in an airtight container in the refrigerator. This practice will help maintain the moisture content of the cheese and prevent contamination.
Additionally, it is advised to use a clean utensil or very clean hands to remove the cheese from the brine solution to avoid introducing any contaminants. Feta cheese can also be frozen for longer-term storage, lasting up to six months. However, it is important to note that freezing may affect the texture and flavour of the cheese.

It is typically ready to eat after a few days, but some varieties are aged for several months. During this time, the cheese is stored in a brine solution and regularly turned to ensure an even distribution of flavours.
Feta has a shelf life of up to six months, but once opened, it is recommended to be consumed within one to two weeks.

Even if the cheese isn't going bad, you'll get a tastier snack if you eat it shortly after opening.
To extend the shelf life of opened feta, it is important to follow proper storage procedures. Feta should be stored in an airtight container in the refrigerator. The brine should be changed every few days, and if it gets too low, it can be topped off with filtered water and salt. This will help the cheese retain its moisture and freshness. Remember to always use a clean utensil or your hands to remove the cheese from the brine to avoid contamination.

It is spoiled when it becomes rubbery, tough and dry
Feta cheese is a beloved and versatile food enjoyed worldwide. It is a brined, white cheese with a salty and tangy flavour, originally from Greece. It is used in many Mediterranean dishes, from appetizers to desserts. Feta is typically made from sheep's milk or a combination of sheep's and goat's milk. It has a unique, crumbly texture and a strong taste.
To maintain its distinctive flavour and texture, feta requires specific handling and storage. Proper storage is critical to prevent the cheese from spoiling prematurely. Feta is typically sold in a brine solution, which helps preserve its freshness and keeps it moist. However, even with proper storage, feta cheese can still spoil.
One indication that feta cheese has spoiled is a change in texture. It is spoiled when it becomes rubbery, tough, and dry. This occurs when the cheese loses its moisture. Instead of being crumbly and moist, spoiled feta becomes difficult to cut or crumble. It may also appear shrivelled or shrunken, indicating moisture loss.
In addition to textural changes, other signs of spoilage in feta cheese include the development of a funny taste. It may become overly sour or develop bitter notes. This change in flavour is a clear indication that the cheese is no longer at its best. Spoiled feta may also exhibit noticeable signs of mold growth, such as dark or green discoloration on the surface.
To prolong the shelf life of feta cheese, it is essential to follow proper storage practices. Feta should be stored in an airtight container in the refrigerator. If the brine solution decreases, it can be topped off with filtered water and salt to maintain the correct salinity and moisture levels. By following these storage guidelines, the risk of spoilage can be minimised, and the feta cheese can be enjoyed for longer.

Its strong smell is due to bacteria and moulds
Feta cheese is a soft, white, brined cheese, originating from Greece. It is made from sheep's milk or a combination of sheep's and goat's milk, with rennet and salt. Feta is a crumbly, salty cheese with a tangy taste, widely used in Mediterranean cuisine.
Feta has a strong smell, which is due to bacteria and moulds. The pungent odour is a result of the natural aging process and the presence of microorganisms, which produce volatile compounds such as propionic acid and butyric acid. These compounds contribute to the cheese's distinct aroma. While some may find the smell unappealing, it is not an indication of spoilage or contamination. In fact, the unique aroma is embraced by many as a characteristic of the cheese.
The aging process of feta gives the cheese its firmer texture and more complex flavour. During this time, the cheese is stored in a brine solution, which preserves it and gives it its salty taste. The brine solution also helps the cheese retain moisture, contributing to its longer shelf life.
To ensure the freshness of feta, it is recommended to store it in an airtight container in the refrigerator. The brine solution should be changed every few days, and the cheese should be completely submerged. Feta can last for up to six months in the refrigerator, although it is recommended to consume it within a week or two of opening for maximum taste and quality.
While feta's strong smell is a characteristic of the cheese, there are indicators to determine if it has gone bad. This includes the development of a funny taste, such as an overly sour or bitter flavour. Additionally, noticeable signs of mold growth or discolouration indicate that the cheese should be discarded.
