How Long Does Feta Cheese Last?

When it comes to enjoying feta at its best, timing is everything. The shelf life of feta cheese can vary based on several factors, including whether it’s been opened, how it’s stored, and the best by date provided by the manufacturer. Let’s break down what you can expect.

Unopened Feta Cheese

In its original packaging, unopened feta can last for several weeks past its printed expiration date if stored properly in the fridge. This is typically due to the brine solution that feta is often packaged in, which helps preserve it.

Opened Feta Cheese

Once opened, feta cheese should be consumed within 5 to 7 days for the best quality and safety. After this time, the risk of spoilage and foodborne illness increases, even if stored in the fridge.

Feta Cheese Stored in Brine

If you transfer your feta into a container of brine (saltwater solution) after opening, it can extend its shelf life for up to 4 weeks in the refrigerator. Ensure the cheese is fully submerged in the brine.

Frozen Feta Cheese

Feta can be frozen for up to 6 months. However, freezing may change the texture, making it crumblier and less creamy once thawed. It’s best used for cooking rather than as a standalone dish after being frozen.

Frozen Feta CheeseUp to 6 months in freezer

Does Feta Cheese Go Bad?

Yes, feta cheese can go bad. Feta cheese goes bad due to a combination of factors that contribute to spoilage in food products, especially in dairy. Here are the key reasons:

  1. Microbial Growth: Dairy products provide a rich environment for bacteria, yeasts, and molds to grow, especially once a product is opened and exposed to the air. The brine solution in which feta is often stored helps to slow down this growth, but it won’t stop it entirely.
  2. pH Changes: Feta cheese has a low pH, which means it’s quite acidic. This acidity helps to keep bacteria at bay initially. However, over time, as it absorbs moisture from the air or if the brine is diluted, the pH can rise to a level that becomes more hospitable to microbes.
  3. Moisture and Humidity: Feta naturally contains moisture, which is essential for its texture but also makes it susceptible to bacterial growth. If the cheese is not stored properly, excess moisture or humidity can lead to faster spoilage.
  4. Temperature Fluctuations: If feta cheese is not kept consistently cold, fluctuations in temperature can encourage the growth of spoilage organisms. Even within the fridge, if the cheese is frequently taken out and left at room temperature, this can accelerate spoilage.
  5. Oxidation: Exposure to oxygen can lead to oxidation, which affects the flavor and quality of the cheese. Once the packaging is opened, oxidation can begin to alter the fatty acids in the cheese, leading to rancidity.
  6. Contamination: Introducing contaminants from utensils, hands, or other foods can introduce spoilage bacteria to feta cheese, which can multiply over time and cause the cheese to go bad.

Because of these factors, it’s important to handle and store feta cheese correctly to minimize the risk of spoilage and extend its shelf life as long as possible.

How to Tell if Feta Cheese Is No Longer Good

When feta cheese isn’t good anymore, your senses are your best tools for determining if it’s time to toss it out. Here’s what to look for:

  1. Off-Putting Smell: Fresh feta cheese has a tangy scent that is characteristic of aged cheeses. However, if your feta starts to emit a strong, sour smell that strikes you as unpleasant or different from when you first opened it, trust your nose—it’s a clear indicator that the cheese may have gone bad.
  2. Discoloration: Feta is traditionally white. If you notice any yellowing or discoloration—such as pink, blue, green, or black spots—that wasn’t there before, it’s likely due to mold or bacterial growth, and the cheese should not be consumed.
  3. Texture Change: Fresh feta should have a firm and crumbly texture. If it feels slimy or develops a gooey or mushy consistency, these are signs of spoilage, particularly bacterial contamination.
  4. Sour Taste: If you’re unsure based on smell and appearance, a small taste can confirm your suspicions. If the cheese tastes sour or just generally off, it’s best not to eat it. Remember, this taste test should be a last resort; visible mold or a bad smell is enough to decide to throw the cheese away.
  5. Mold Growth: While some cheeses are made with mold and are safe to eat, mold on feta cheese is not a good sign. If there’s mold on any part of your feta cheese, it’s best to discard the entire piece, as the contamination can spread beyond visible spots.

If your feta cheese exhibits any of these signs, it’s safest to discard it to avoid the risk of foodborne illness. Remember, it’s better to be safe than sorry when it comes to consuming dairy products that may have gone bad.

Storing Feta Cheese for Maximum Freshness

The key to enjoying feta cheese at its best is proper storage. By storing feta correctly, you ensure that it retains its delectable flavor and crumbly texture for as long as possible. Let’s delve into the best practices that will keep your feta cheese just as delightful as the day you bought it.

Best Practices for Refrigerating Feta

Refrigeration is vital for maintaining the freshness of feta cheese. Here’s how to do it right:

  • Keep it in Brine: If your feta doesn’t come in brine, make your own by dissolving salt in water until it tastes as salty as the sea. Submerge the cheese in this solution, which will help maintain its moisture and slow down bacterial growth.
  • Airtight Containers: After opening, transfer feta to an airtight container to keep out odors and contaminants from other foods in your fridge.
  • Use Plastic Wrap: If you don’t have an airtight container, tightly wrap the cheese in plastic wrap, ensuring minimal air can reach it.
  • Consistent Temperature: Store your feta in a part of the refrigerator that maintains a consistent temperature, ideally at or below 4°C (39°F).

Following these tips can significantly extend the life of your feta cheese, keeping it fresh and tasty for your next culinary adventure.

Can You Freeze Feta Cheese?

The topic of freezing feta cheese is up for debate. While freezing can extend its shelf life, it may also alter its texture. Here’s what you need to know if you choose to freeze your feta:

  • Texture Changes: Expect a change in texture once thawed. Feta may become crumblier and less creamy, which could be perfect for baked dishes or crumbled toppings.
  • Preparation for Freezing: Drain the brine and pat the cheese dry. Cut into portions you’ll use later to avoid thawing more than you need at one time.
  • Wrapping for Freezing: Wrap the portions tightly in plastic wrap and then place them in a freezer bag or airtight container to prevent freezer burn.
  • Thawing: When ready to use, thaw the cheese in the refrigerator for several hours or overnight. It’s best to plan ahead to avoid a quick thaw that could lead to texture changes.

Freezing feta cheese is a practical option if you find yourself with more feta than you can consume in the short term. While the texture might be impacted, the flavors will remain intact, making frozen feta ideal for cooked applications where its creaminess is less critical.

Storing Feta Cheese Blocks

Storing whole blocks of feta cheese effectively can greatly extend their freshness and taste:

  • In Brine: The best way to store a block of feta is submerged in a brine solution. This keeps it moist and preserves its tangy flavor. Place the block in a container, cover it with brine, and seal with a lid.
  • Wrapped Tightly: If brine isn’t an option, wrap the block tightly in wax paper or plastic wrap. Then, place it in a zip-top bag, squeezing out as much air as possible before sealing.
  • Regular Checks: Every few days, check the cheese for any signs of spoilage and change the brine if it starts to look cloudy or if the cheese develops a sour smell.

By storing blocks of feta in brine or keeping them well-wrapped and refrigerated, you can maintain their quality until you’re ready to enjoy them.

Storing Crumbled Feta Cheese

Crumbled feta cheese requires a slightly different approach due to its increased surface area and susceptibility to drying out:

  • Air-Tight and Dry: Store crumbled feta in an airtight container without brine. The smaller pieces can become overly soggy in brine, which may lead to textural changes.
  • Portion and Freeze: If you have a large amount, consider portioning it out. Crumbled feta freezes quite well, and you can take out just the amount you need, when you need it.
  • Avoid Contamination: Use a clean spoon each time you take some feta out of the container to prevent introducing bacteria that could lead to spoilage.

Crumbled feta should be kept dry and refrigerated when not being used, and as with blocks of feta, always be on the lookout for any changes in smell or appearance that indicate it’s time to discard the cheese.

Tips for Handling Feta Cheese

Handling feta cheese with care from the moment you pick it up at the supermarket to when you serve it in your kitchen is crucial for preserving its quality and extending its shelf life. Below are some pro tips to ensure you’re making the most out of every block or crumble of feta.

Serving Feta Cheese Safely

When it comes to slicing and serving feta cheese, a few simple practices can go a long way in keeping it fresh and safe to eat:

  • Use Clean Utensils: Always use clean knives and cutting boards when slicing feta cheese to prevent cross-contamination from other foods.
  • Portion Control: Cut only the amount of feta you plan to use. The less the cheese is handled and exposed to air, the longer it will last.
  • Hands-Off: Try to handle the cheese as little as possible with your hands. If necessary, wash your hands thoroughly before touching the cheese.
  • Serving Temperature: Feta cheese is best served at room temperature. Remove it from the fridge about 30 minutes before serving to allow its flavors to fully develop.

Following these steps ensures that every serving of feta cheese is not only delicious but also safe for consumption.

Managing Leftover Feta

Don’t let leftover feta cheese go to waste. With a bit of creativity, you can use up every bit:

  • Refrigerate Promptly: Store any leftover feta in the refrigerator as soon as possible. If it has been sitting out for two hours or more at room temperature, it’s best to discard it to avoid the risk of foodborne illness.
  • Creative Recipes: Leftover feta is great in a variety of dishes. Crumble it over salads, stir it into scrambled eggs, or add it to your favorite pasta dish for a burst of flavor.
  • Preserving in Oil: For a longer shelf life, consider preserving leftover feta in olive oil. This method not only keeps the cheese fresh but also infuses it with additional flavor. Just ensure the cheese is fully submerged in the oil and stored in the fridge.
  • Freezing Options: If you can’t use the leftovers soon, freezing crumbled feta is a practical option. Frozen feta works well in cooked dishes where its creamy texture is not as crucial.

By implementing these tips, you can enjoy your feta cheese in various forms and flavors, making sure that not a single crumble is wasted.
