Yeast is an essential ingredient in many baking recipes. There are various forms of yeast that you should be acquainted with, particularly if you want to bake bread or other foods that need a leavening agent.

Yeast, in general, needs refrigeration for storage. Place the yeast in an airtight jar in the refrigerator. Both active dry yeast and quick yeast are affected by this. To avoid spoiling, split the yeast and cover it in aluminum foil since new yeast is light sensitive.

How Should Active Dry Yeast Be Stored After Opening?

In general, after active dry yeast has been opened, it should be refrigerated. If kept properly, active dry yeast may last up to four months in the refrigerator. Keeping the yeast in an airtight container prevents moisture from sneaking in and ruining it.

The following table shows the estimated shelf life of yeast once opened:

Type of Yeast Room Temperature Refrigerator Freezer
Instant Yeast Up to 2 months Up to 4 months Up to 6 months
Active Dry Yeast Up to 3 months Up to 4 months Up to 6 months
Fresh Yeast Up to 2 weeks 3-4 weeks Up to 3 months
*These numbers are for storage in air-tight containers

If you need airtight storage containers, I suggest the Rubbermaid Brilliance Leak-Proof Food Storage Containers with Airtight Lids.

I’ve been using these containers for a few years and have successfully kept all of my food and baked products at room temperature, in the fridge, and in the freezer. I’ve even cooked with them in the microwave! These containers come in a variety of sets, so choose the best one for you. These containers are available on Amazon!

Active dry yeast should always be kept in a cold, dry place away from moisture. A closet or pantry is a fine place to start, but once opened, you’ll need to take extra precautions to keep it from rotting.

After you’ve opened active dry yeast, the best way to store it is in a food-safe container with a tight-fitting cover. This will shield it from the elements. It may be kept in the fridge for up to four months.

You may also store your active dry yeast in the freezer to increase its shelf life.

Keep it in the freezer with the same care that you would in the refrigerator, and your yeast will last up to six months.

How Should You Store Instant Yeast Once It’s Been Opened?

In order to remain fresh, instant yeast should be kept in the refrigerator or freezer. To minimize spoilage, it should also be kept in an airtight container. This keeps the yeast from being exposed to moisture, which speeds up deterioration.

While utilizing instant yeast, the storage preparation and shelf life will be quite comparable to active dry yeast. While your instant yeast can keep for roughly two years if kept sealed, once opened, you must take steps to prevent deterioration.

Exposure to air is your instant yeast’s enemy when it comes to remaining fresh.

Exposure may drastically reduce its longevity, so keep it in a sealed container. A glass mason jar with a tight-fitting lid is an excellent storage container for instant yeast, keeping it fresh for up to four months in the fridge and six months in the freezer.

If you choose to freeze your fresh yeast, be sure to properly wrap and cover it in cling wrap and parchment paper to preserve it from the outdoors.

To do this, I propose purchasing an Impulse Poly Bag Heat Sealer, which melts one layer of plastic into another, forming a powerful permanent seal that can only be destroyed by cutting or tearing it apart. You can find it on Amazon!

To minimize freezer burn and deterioration, ensure sure there are no exposed regions on your fresh yeast.

Its dark hue indicates that it has deteriorated.

Active, healthy yeast has a unique aroma, similar to freshly made bread. This odor indicates that the yeast is healthy and active. If you take your yeast out to prove and it no longer has that distinct odor, it has most likely expired.
