Once opened, feta cheese typically lasts about five to seven days if stored properly. To maximize its shelf life, it is essential to keep feta cheese in the right conditions. Storing it in the refrigerator is crucial, ideally in its original brine solution. The brine, a mixture of water and salt, helps maintain the cheese's moisture and flavor while inhibiting bacterial growth. If the cheese comes without brine or you’ve discarded it, you can create a homemade solution by dissolving salt in water to submerge the feta. It's best to use an airtight container to prevent exposure to air, which can lead to drying and spoilage. Feta can also be wrapped tightly in plastic wrap or aluminum foil if brine is unavailable. Be mindful of any changes in smell, texture, or appearance, as these could indicate spoilage. A sour odor, slimy texture, or mold growth are signs that the cheese should not be consumed. While freezing feta is an option for extending its life, it may alter the texture and flavor, making it more suitable for cooking rather than salads or fresh dishes. Proper storage practices ensure that feta cheese remains safe and enjoyable for as long as possible.

How to store feta and tell when it's gone bad

Feta is a perishable product and should always be kept in the refrigerator at temperatures below 40 degrees Fahrenheit. It's crucial to retain the brine, as it plays a key role in preserving the cheese's flavor and freshness. When you open a package, be sure not to discard the brine; this salty water is what the cheese is intended to be immersed in. If you accidentally pour out the brine, you can create a substitute by mixing 1 teaspoon of kosher salt with 1 cup of water; adjust the quantities as needed.

You can also freeze feta. Simply drain the brine, then wrap the cheese in freezer-safe materials, such as plastic wrap followed by aluminum foil; it can be stored this way for up to three months.

If you're unsure how long the feta has been in the fridge, there are several indicators of spoilage. Look for any visible mold; feta is typically an ivory or slightly off-white color, so any green spots or discoloration mean it has gone bad. If it appears fine but you're still uncertain, tasting it can help. Feta should have a mild tang, but if it tastes unpleasantly sour, it's best to discard it. Additionally, if it has a bread-like flavor, that indicates yeast growth, and it should also be thrown away.
