Feta cheese is a popular ingredient in many dishes, but it's important to store it properly to prevent it from going bad. Feta is traditionally preserved in a salty brine solution, which can keep it fresh for up to six months if unopened and stored correctly. However, once opened, feta should be consumed within a week or two to ensure optimal taste and texture. To extend the shelf life of opened feta, some people recommend storing it in olive oil, which can keep it fresh for up to three weeks. Storing feta in brine or olive oil helps retain moisture and protects it from bacteria, yeast, and other microbes that can cause spoilage.

What You'll Learn
Feta in brine can last up to six months unopened
Feta cheese is a delicious, tangy treat, but it can be hard to get through a whole block before it goes bad. Luckily, feta in brine can last up to six months if it is unopened. This is because the brine is a classic preservation method that keeps the cheese fresh for longer. The salty brine solution helps the cheese retain its moisture, just like how mozzarella stays fresh in its brine.
To keep your feta in brine lasting as long as possible, it's important to store it correctly. Firstly, make sure the cheese is completely submerged in the brine. If the liquid level is looking low, you can top it off with a mixture of filtered water and salt. Dissolve about two teaspoons of kosher salt in one to two cups of water, depending on how salty you want your cheese to be.
It's also important to keep the brine uncontaminated. Always use a utensil or very clean hands to handle the cheese and brine. This will help to avoid introducing microbes into the feta's environment, which could cause it to spoil.
While unopened feta in brine can last up to six months, it's recommended that you eat opened feta within one to two weeks to enjoy it at its best. If you want to extend the shelf life of your opened feta, you can store it in olive oil, which can keep it fresh for two to three weeks. The fat in the olive oil creates a barrier around the cheese, protecting it from outside contaminants.

Unopened feta should be fully immersed in brine
Feta cheese is traditionally sold immersed in brine, a classic preservation method that can keep the cheese fresh for up to six months if unopened and stored correctly. The salty brine solution helps the cheese retain its moisture, preserving it for longer. However, this method of preservation relies on the feta being fully immersed in the brine.
If the feta is not fully covered by brine, it is susceptible to spoilage. This is because the brine creates a protective barrier around the cheese, effectively sealing it off from outside contaminants such as bacteria, yeast, and other microbes. Without this protective barrier, the cheese is exposed to these contaminants, which can cause it to go bad.
To prevent this, it is important to ensure that the feta is always fully immersed in brine. If the brine level gets low, it can be topped off with a mixture of filtered water and salt. Approximately two teaspoons of kosher salt can be dissolved in one to two cups of water, depending on the desired saltiness. It is also important to use clean utensils or hands when removing the cheese from the brine to avoid introducing microbes that could cause spoilage.
By keeping the feta fully immersed in brine and following proper storage practices, unopened feta can be preserved for up to six months, ensuring it remains fresh and tasty for a longer period of time.

Crumbled feta sold without brine can get mouldy
Feta cheese is traditionally sold in a briny solution, which is a classic preservation method that helps the cheese retain its moisture and keeps it fresh for longer. However, crumbled feta is often sold without any brine, which means it is more susceptible to spoilage.
When feta cheese is submerged in brine, it can last for up to six months if stored correctly. The salty brine acts as a barrier, protecting the cheese from outside contaminants such as bacteria, yeast, and other microbes. However, without the brine, feta cheese will only stay fresh for a few weeks, even when stored in the refrigerator.
One of the main issues with crumbled feta sold without brine is that it can get mouldy. This is because the cheese is exposed to air and other contaminants that can encourage the growth of mould. Mould can develop even if the feta is stored in an airtight container, as mould spores can still be present in the air.
To prevent mould from growing on crumbled feta, it is important to store it correctly. One option is to create your own brine solution by mixing whole milk, water, table salt, and distilled white vinegar. Placing the crumbled feta in this brine solution will help to preserve it for longer. Another option is to store the crumbled feta in olive oil, which can extend its shelf life by two to three weeks. The fat in the olive oil creates a barrier, protecting the cheese from outside contaminants.
It is also important to handle the cheese with clean utensils and hands to avoid introducing microbes that can cause spoilage. Additionally, it is recommended to check the feta cheese periodically for signs of spoilage, such as a yeasty aroma or harsh, unbalanced flavours. If the cheese has developed mould, it should not be consumed.

Opened feta should be consumed within a week or two
Feta cheese is a popular tangy, salty, and slightly sour cheese that is often sold in a brine solution. This briny solution is a classic preservation method that can keep the cheese fresh for up to six months if unopened and stored correctly. However, once the feta cheese is opened, it is recommended to consume it within one to two weeks.
Opened feta cheese should be consumed within a week or two. This is because, after opening, the cheese is exposed to air and contaminants, reducing its shelf life. The original brine solution helps to preserve the cheese by keeping it submerged and preventing microbial growth. However, once the seal is broken, the brine may not be as effective, and the cheese is more susceptible to spoilage. Consuming the cheese within a shorter timeframe reduces the risk of foodborne illnesses and ensures a better taste and texture experience.
To extend the shelf life of opened feta cheese, some sources suggest storing it in olive oil. The fat in olive oil creates a barrier around the cheese, protecting it from bacteria, yeast, and other microbes. This method can keep the feta cheese fresh for up to two to three weeks. It is important to note that the olive oil will alter the taste of the cheese, giving it a more complex and aromatic flavour.
If you are working with crumbled feta cheese, it can be stored in its original container without any trouble. However, it is important to note that crumbled feta is often sold without any brine, so it is more susceptible to mould and spoilage. One solution is to freeze the crumbled feta, which can preserve it in its original condition. Freezing is not recommended for blocks of feta cheese as it can negatively affect the texture, making it overly crumbly.
When determining if feta cheese has gone bad, there are a few indicators to look for. Firstly, if the cheese has developed a yeasty or dough-like smell, it has gone bad. Secondly, if the cheese has harsh, unbalanced flavours such as overly sour, bitter, or rancid notes, it is past its prime. Additionally, noticeable signs of mould growth, such as dark or green discolouration, indicate that the cheese is no longer safe to eat.

Olive oil can extend the shelf life of opened feta
Feta cheese is a traditional cheese that is often preserved in a brine solution, which can help keep it fresh for up to six months if stored correctly and unopened. However, once opened, feta has a much shorter shelf life of about a week. To extend the shelf life of opened feta, you can store it in olive oil.
Olive oil helps maintain the salt content of feta and keeps it moist, thereby extending its shelf life. The fat in the olive oil creates a protective barrier around the cheese, preventing the growth of bacteria, yeast, and other microbes. This barrier also helps delay spoilage, keeping the feta fresh for two to three weeks longer.
Storing feta in olive oil not only prolongs its life but also enhances its flavour. The cheese absorbs the aromatic compounds present in the olive oil, resulting in a more complex and robust taste. The type of olive oil used will impact the flavour. For example, extra virgin olive oil adds a peppery note, while light olive oil offers a milder, more neutral taste.
Additionally, you can add herbs and spices to the olive oil for further flavour enhancement. Options include fresh rosemary, crushed red pepper flakes, garlic, and lemon zest. Experimenting with different combinations allows for a unique and personalised taste experience.
While olive oil is an effective preservative, it is still important to periodically check the feta for signs of spoilage. If the cheese develops a yeasty or dough-like smell, it has gone bad. Properly stored feta in olive oil should remain fresh for the full duration of its extended shelf life.
