If you’re a fan of making your own water kefir at home, you may find yourself with a surplus of water kefir grains. These living organisms need to be cared for properly in order to maintain their health and vitality. One common method of storing water kefir grains is by freezing them.
Freezing water kefir grains is a simple and effective way to preserve them for extended periods of time. The process involves cleaning and prepping the grains before placing them in an airtight container or bag and placing them in the freezer. This method can be especially useful if you plan on taking a break from making water kefir or if you want to share your grains with others.
Before freezing your water kefir grains, it’s important to ensure that they are clean and free from any contaminants. Rinse the grains thoroughly with filtered water to remove any excess sugar or residue. Avoid using tap water as it may contain chlorine or other chemicals that could harm the grains.
Once the grains are clean, place them in a glass jar or airtight container, and cover them with filtered water. It’s important to leave some room for expansion, so don’t fill the container to the top. You can also add a small amount of sugar to the water to provide the grains with some nutrients during their time in the freezer.

2. Glass Jars with Airtight Lids
If you prefer to avoid plastic, glass jars with airtight lids can be a great option. Mason jars or similar containers are ideal for freezing water kefir grains. Make sure the jars are made of thick, freezer-safe glass to prevent cracking. The airtight lids will keep out moisture and maintain the quality of the grains.
Tip: When using glass jars, leave some headspace at the top to allow for expansion as the water kefir grains freeze.
3. Silicone Ice Cube Trays
An alternative option is to use silicone ice cube trays. These trays are flexible, making it easy to remove individual frozen kefir grains when you need them. Choose trays with lids or cover them with plastic wrap to prevent freezer odors from affecting the grains.
Summary
Choosing the right containers for freezing water kefir grains is crucial to preserve their quality and ensure easy access. BPA-free plastic containers, glass jars with airtight lids, and silicone ice cube trays are all suitable options. By using the right containers, you can store water kefir grains in the freezer and enjoy them whenever you’re ready to make a new batch of delicious kefir water.
Freezing the Water Kefir Grains Correctly
When it comes to storing water kefir grains in the freezer, it is important to follow the correct procedure to ensure their survival and viability. Freezing can be a great option if you need to temporarily put your water kefir grains on hold or if you want to preserve them for future use.
Here are the steps to correctly freeze water kefir grains:
- Prepare the water kefir grains by rinsing them thoroughly with filtered water.
- Pat the grains dry with a paper towel, removing any excess moisture.
- Place the grains in an airtight, freezer-safe container. It is recommended to use a small glass jar or a plastic storage bag.

- Transfer the grains to a clean jar and proceed with the regular water kefir-making process.
By following these steps, you can safely freeze and store your water kefir grains without compromising their quality or health. Remember to always use high-quality filtered water and avoid exposure to extreme temperatures or contaminants to ensure the long-term vitality of your water kefir grains.
Thawing and Reviving Frozen Water Kefir Grains
Once you have successfully stored your water kefir grains in the freezer, it’s important to know how to thaw and revive them when you are ready to use them again. Follow these steps to bring your frozen water kefir grains back to life:
Step 1: Thawing
Remove the frozen water kefir grains from the freezer and place them in a clean container or jar.
Leave the container at room temperature and allow the grains to thaw naturally. This process may take several hours or up to a day.
Step 2: Reviving
Once the water kefir grains have thawed completely, discard any excess liquid that may have accumulated during the thawing process.
Rinse the grains gently with filtered or chlorine-free water to remove any residual ice crystals.
Transfer the rinsed grains to a new jar or container and add fresh sugar water, following your usual water kefir brewing recipe.
Place the jar in a warm spot, ideally between 68°F and 78°F (20°C and 25°C), and cover it with a cloth or paper towel to allow for airflow.
Allow the water kefir grains to ferment for 24 to 48 hours, depending on your preference and the temperature of the room.
Following these steps should help you successfully thaw and revive your frozen water kefir grains. It’s important to note that the fermentation process may take a bit longer initially after freezing, but with time and subsequent batches, the grains should regain their usual fermentation activity.
Tips for Maintaining Water Kefir Grains’ Viability in Freezer
Freezing water kefir grains is a common method for storing them when you don’t plan on using them for an extended period of time. However, it is important to follow certain guidelines to ensure the viability and health of your grains. Here are some tips to help you maintain the viability of your water kefir grains while they are in the freezer:
- Ensure grains are in good condition before freezing: Before freezing your water kefir grains, make sure they are healthy and in good condition. Avoid freezing grains that are damaged or weak, as they may not survive the freezing process.
