Water Kefir Guide


What you may need:

It is a good idea to keep designated containers, spoons or strainers. Any unwanted food or soap residue from undesignated dishes may harm the grains. If washing, use very little soap and rinse well.

Water Kefir Grains.
Sugar Source: Organic Cane Sugar, Organic Molasses, Maple Syrup, Coconut Sweetener/Nectar, Organic Demerara, etc.
Spring water, hard well water, mineral water, filtered water, ozonated water.
  -If tap water is your only option, the ideal way to treat it is to ozonate the water. Allow the ozone to dissipate for 24 hours before using it with kefir.
  -Alternatively you can put the tap water into a blender for 15min to evaporate the chlorine. This may lead to problems though as it is hard to designate a blender jar for this purpose. You may end up with food contamination with this method.
  -Another method is to boil and cool the water in a glass pot. Boiling the water may lead to problems if using a metal pot. Also remember that if it is not a designated pot, you may end up with food contamination.
64 oz Wide mouth Mason jar.

Plastic Lid for Mason jar.

Designated measuring cup & wood or glass spoon.
Designated plastic strainer (preferably nylon soft mesh). A metal sieve can be used as a last resort, but not recommended.
Designated large glass or plastic bowl.

White sugar is often preferred because it is usually the easiest and most affordable. Buying organic can be important to keep grains healthy. To sustain healthy grains on white sugar long term, it is recommended that a minerals and/or a mineral sugar like organic blackstrap molasses occasionally be added.


Stevia or chemical sugar substitutes.
Honey. It has antimicrobial properties and will damage your grains.
Chlorinated tap water.
Any heat over 40C may kill your grains.
Do not use water filtered through a carbon activated filter (ie. Britta).
Radapura is not recommended as many tests have shown that the kefir grains have trouble growing in them.
Try to avoid dried fruits that have a sulfate preservative. It can be used that any non-organic preserved fruit may contain sulfate even though it is not on the label.

Rehydration (For Dehydrated Grains)

Dehydrated kefir grains have a long shelf life if stored properly. They are a good idea to have on hand as a backup, should your gains die off. They will take longer to reactivate because they need time to re-balance their micro flora, but they will eventual produce the same product as live grains.

It takes 3 to 5 days in sweet water to re-hydrate and get them fermenting again. But it may take up to 3 weeks to get the full benefits.

Use 2 tsp of dried grains. They will re-hydrate into about 2-4 Tbsp.

1) Use a Clean Mason Jar with a plastic lid.

2) Dissolve 1/4 - 1 Tbsp of sugar in 2 cups water (If using white or cane sugar, you may include 1/4 tsp of organic blackstrap molasses).

3) Add additional minerals (Optional). 1/8 tsp of Terramin Clay or 1/16 tsp of Baking Soda.

4) Allow it to sit for 8 Days (Between 6-9 Days is ok). It is helpful to stir the mixture once a day, do this by rotating the jar around. Do not allow the mixture to sit for longer than 9 days.

5) Strain the kefir grains and discard the liquid.

Fermentation (For Live Grains)

During the fermentation process, the water kefir grains will grow and convert your sugar water into water kefir. After 8 Days all of the sugar will have been converted into a valuable probiotic drink.
If your grains were mailed to you, they may need a fermentation or two to revive them fully. Sometimes this may depend on temperature and other variables. This first batch may not be drinkable and sometimes very little will happen, especially if you use too much liquid for the amount of grains (This is a common error). If nothing happens the amount of water can be reduced and the sugar increased. Also please note that water kefir grains breaks apart very easily, if they arrive in very small pieces it does not mean they are damaged, it could actually speed growth due to more surface area. Kefir is alive, so worrying about them could affect them in a negative way.

****IMPORTANT If you are starting with a small amount of grains (3 Tbsp or so) please follow the starter batch directions and slowly increase the proportions until you have enough grains for a full batch.

Starter Batch (3 Tbsp of Grains)

1) Mix together 2 Cups of water and 1/4 - 1 Tbsp of sugar in a clean mason jar with plastic lid.
*If you would like more growth in the beginning stages you may want to start with 2 Tbsp of sugar, and then reduce the sugar afterwards.

2) Optional - Add a pinch of minerals. If you are unsure about the type of mineral you are using please wait until the grains start growing. I have found Terramin clay to be the best mineral supplement. Add 1/8 tsp of Terramin Clay or a drop of Organic Molasses. (If using white sugar, you may want to include the Blackstrap Molasses)

3) Add your 3Tbsp of Kefir grains.

4) Snugly tighten the lid on the jar and leave sit out of direct sunlight for at least 8 days and a miximum of 10 days. Burping is not necessary, as the lid will allow excess gas out.

5) After the 8 days strain out the liquid. Using very fine strainer in the beginning will help catch the small grains and will speed your growth time. Store the water Kefir drink in the refrigerator for up to 10 weeks.

 -Use this recipe and increase the amounts until your grains grow enough to make the recipe below.
 *If you are having trouble with fermentation then reduce liquid to 1 cup.
 *If you you would like to speed the growth of the grains, increase sugar to 2 Tbsp.

Basic Recipe (Minimum of 1/2 Cup of grains needed)

**Warning** - If you only have 3 Tbsp of grains , this recipe will not work, please follow the directions directly above and increase the amounts as your kefir grows.

1) Mix together 1/4 cup of sugar and 8 cups of water.

2) Optional - Add minerals. 1/4-1/2 tsp of Terramin Clay occasionally will keep your grains very healthy. 1/16 tsp of baking soda may be used.

3) Add Optional Flavoring.
 -I recommend not to add flavoring until after fermentation

4) Add 3/4 - 4 cups of Kefir grains.

5) Kefir likes to be moved around while it is fermenting. People used to hang bags of kefir in doorways so that they would get bumped throughout the day. Try to leave the kefir in a place where it will get moved around, perhaps on a table that gets used throughout the day. Alternatively just picking up the jar and rotating it can be helpful.

6) Leave your kefir out of direct sunlight for at least 8 days and a maximum of 10 days. A room temperature of 14C 25C is ok and a maximum temp of 32C can be tolerated. After 8 days all of the sugar will have been converted into something safe and valuable for the body.

7) Strain out the kefir grains using a fine mesh strainer (preferably nylon). Store the water kefir drink in the refrigerator for up to 10 weeks.

Second Fermentation

 -Second fermentation is not used with this method.


It is approriate for most adult to consume about 1/2 cup of water kefir at a time,. Take up to 3 times a day after meals.
For most people kefir should not be consumed over extended periods of time without taking occasional breaks. The sody sometimes needs breaks so that it does not become dependent on the kefir bacteria. Ingesting every 1-3 days is usually good, if taking every day, then 3 weeks on and 3 weeks off is a good approach.
My favorite way to consume kefir water would be too add crushed raspberries before drinking. But it is also very enjoyable plain on ice. Use 1/4 cup of raspberries to 1/2-1 cup kefir.

Storing & Dehydrating

The grains can be stored in the fridge for a few weeks. To do this make a fresh batch of sugar water with the kefir and place in fridge. This will last 4 weeks

Dehydrating kefir grains is always a good idea to have as a backup. To dehydrate extra grains, put them on a paper towel or smooth cloth and leave near a fan in a well ventilated area for 1 to 2 days. Store in a sealed jar and place in a cool, dry, dark place. A silica pouch can be added for longer shelf life.

Transporting & Travelling

Water kefir grains can be transported without liquid, in a ziplock bag or glass jar, at up to 28 Deg Celsius. Store them in a place where they wont get squished, or put the ziplock bag into the glass jar. They would last well like this for up to two weeks. If they travel for over 8 day then they will need to reactivate the first batch. After traveling they should be fed for another 3 weeks to stabilize before another trip.
