How To Tell If Feta Cheese Has Gone Bad/How To Know If Feta Cheese Is Fresh

Feta cheese has some very distinct characteristics that can help you determine its level of freshness.

Fresh feta cheese: Fresh feta cheese should be tangy, rich, and a little salty. Feta cheese that has been made with sheep’s milk will have a rich and buttery flavor while feta cheese made with goat’s milk will be harder and have a milder flavor.

Similarly, feta cheese that has gone bad has some particular things that should be looked for to determine whether or not it is still good to eat.

Smell it: Smell is a very good indicator of spoilage. Smell your feta cheese and if it smells sour or in any way unpleasant, it should not be eaten.

Check for sliminess: If the feta cheese that is submerged in brine has become slimy, it won’t be at its best quality. This happens because the ph balance is off. The brine has leeched calcium from the cheese. While you may not get sick, it may be unpleasant to eat.

Check for mold: If the cheese has grown mold or you see any dark specs it is best to get rid of it.

Check the texture: Feta cheese that is past its prime can dry out. While still safe to eat, the texture and the taste will not be pleasant.

How To Store Feta Cheese

Feta cheese is very crumbly and can dry out quickly. If you want to keep your feta fresh for more than a week, it should be kept in brine.

Protect it from the air: Feta cheese should always be protected from air to prevent it from drying out too quickly. It is typically sold in a brine and should be kept in the brine to keep it moist.

Prepare a brine: If there is not enough brine to keep your feta cheese covered, you can make your own to add to the container. This can be done by dissolving 2 tsp. of salt in 1 cup of water.

Can You Freeze Feta Cheese?

Feta cheese can be frozen but the cheese can be affected by freezing. Frozen feta cheese can lose a little of the flavor and can become crumblier. While some changes are unavoidable, proper storage can help maintain the quality of your feta cheese.

Blocks of feta cheese:

Drain it: If the block is bought in brine, it should be drained. If it is unopened, you should open it and drain the brine.

Dry it: Pat the cheese dry with paper towels. Don’t pat it until it is completely dry because that will cause it to dry up.

Divide it: Divide the block into portions depending on how much you will use at one time.

Package it: Wrap each portion with plastic wrap to protect it from freezer burn. Put the wrapped portions into freezer bags and remove as much air as possible.

Crumbled feta cheese:

Divide it: While not necessary, you can portion the crumbled feta cheese before you freeze it.

Package it: Crumbled feta can be stored in the plastic container it comes in and for added protection, you can wrap it in plastic wrap and stick it in a freezer bag.

Coldwater bath: If you need the cheese sooner, you can put the container in a bowl of cold water. This method will defrost the cheese in 1 to 2 hours.
