Feta, a staple in Greek cuisine, is a tangy and crumbly cheese that adds flavor to various dishes, from salads to pastries. However, its delicate nature raises concerns about its shelf life, particularly after opening. In this article, we will delve into the world of feta, exploring its characteristics, storage methods, and the factors that affect its longevity.
Understanding Feta Cheese
Before we dive into the shelf life of feta, it’s essential to understand its composition and production process. Feta is a type of brined cheese, typically made from sheep’s milk or a combination of sheep’s and goat’s milk. The cheese is cured in a salty brine solution, which gives it a distinctive flavor and texture.

Feta is a delicate cheese that can be easily contaminated. Always handle the cheese gently, and avoid touching it excessively, as the oils from your skin can transfer to the cheese.
How Long Can Feta Be Opened For?
The shelf life of opened feta depends on various factors, including storage conditions, handling, and the age of the cheese. Generally, opened feta can last for:
- 1-2 weeks in the refrigerator, stored in an airtight container
- 6-8 months in the freezer, wrapped tightly in plastic wrap or aluminum foil
It’s essential to note that feta’s quality and flavor will degrade over time, even if it’s stored properly. If you notice any signs of spoilage, such as mold, sliminess, or an off smell, it’s best to err on the side of caution and discard the cheese.
Signs of Spoilage
Keep an eye out for the following signs of spoilage:
- Mold or yeast growth
- Slimy or soft texture
- Off smell or sour taste
- Slime or liquid on the surface of the cheese
If you notice any of these signs, it’s best to discard the feta immediately.
Conclusion
Feta is a delicate cheese that requires proper storage and handling to extend its shelf life. By understanding the factors that affect its longevity and following proper storage methods, you can enjoy your feta for a longer period.

What is the typical shelf life of unopened feta cheese?
The typical shelf life of unopened feta cheese can vary depending on the type, packaging, and storage conditions. Generally, a block of feta cheese can last for several months when stored properly in the refrigerator. If the feta is packaged in a brine solution, it can last longer than if it’s packaged in a vacuum-sealed container or wrapped in plastic wrap. On average, unopened feta cheese can last for 3 to 6 months in the refrigerator.
It’s essential to check the expiration date or “best by” date on the packaging to determine the recommended shelf life. Even if the feta is still within its shelf life, it’s crucial to inspect the cheese for any visible signs of spoilage before consuming it. If the feta has an off smell, slimy texture, or mold growth, it’s best to err on the side of caution and discard it.
How long can opened feta cheese be stored in the refrigerator?
Once opened, feta cheese can be stored in the refrigerator for a shorter period than unopened feta. The shelf life of opened feta cheese depends on how well it’s stored and handled. If the feta is wrapped tightly in plastic wrap or aluminum foil and kept in the refrigerator at a consistent temperature below 40°F (4°C), it can last for 1 to 2 weeks.
It’s crucial to keep the feta away from strong-smelling foods, as it can absorb odors easily. If you notice any mold growth, sliminess, or an off smell, it’s best to discard the feta immediately. You can also consider freezing the feta to extend its shelf life. Freezing will help preserve the cheese, but it may affect its texture and flavor.
Can feta cheese be frozen to extend its shelf life?
Yes, feta cheese can be frozen to extend its shelf life. Freezing is an excellent way to preserve feta, especially if you don’t plan to use it within a few weeks.
