The sugar and water you use to make water kefir can impact the flavour and carbonation level of your finished water kefir and may even affect the health of your water kefir grains.
If your water kefir is too sweet for your taste or too flat after bottling the finished water kefir, you may want to try a different type of sugar.
If your water kefir grains do not appear to be active, you may simply need mineral supplementation or a different sugar and water combination.
How to choose a sugar for making water kefir
When choosing a sugar for making water kefir, always read the label. Some sugars may contain anti-caking additives or other ingredients that could affect the health of the water kefir grains. Look for plain sugar with no added ingredients, for best results.
Use the following table as a guide to sugar use and its effects.
|Sugar Type||Description||Results and Recommendations|
|Refined white sugar||Pure white, free of minerals||Makes a sweet water kefir|
|Organic Cane Juice Crystals||Less refined than white sugar; very low mineral content||Makes a sweet water kefir|
|Turbinado or Raw Sugar||Sugar that is spun to have most of the molasses removed; medium mineral content||Makes a less sweet water kefir than white sugar|
|Rapadura or Sucanat||Sugar cane juice that has been pressed and dried; high mineral content||Makes a stronger-flavored water kefir|
|Brown Sugar||White sugar with molasses added back; high mineral content||Makes a stronger-flavoured water kefir|
|Coconut Palm Sugar||Sugar extracted and dried from coconut palm trees; very high mineral content||Use small amounts only in combination with cane sugar.|
|Maple Sugar or Syrup||Made from the sap of the sugar maple tree||Too rich for water kefir and can damage water kefir grains. Use small amounts only in combination with cane sugar.|
|Honey||Natural sugar from bees; high in mineral content||Raw honey has its own bacteria that can compete with water kefir grains; some honey is contaminated with high fructose corn syrup. We DO NOT recommend using this for making water kefir.|
|Molasses||Very high mineral content||Used on its own, molasses can be damaging to water kefir grains. We recommend using only ½ tsp. as mineral supplementation per batch, as needed.|
|Agave, stevia, monk fruit, Splenda||Sugar substitutes||Unfortunately, these substitutes do not provide the food necessary for water kefir grains. We DO NOT recommend using these for making water kefir.|
You can experiment with different kinds of sugar, and if you’re ever having trouble fermenting, try a new sugar, it should just be that the grains need some different vitamins or minerals that could be provided from a different sugar.
Happy Gut water kefir kits include the perfect mixture of organic cane sugar and organic coconut palm sugar. We take the guesswork out of picking a sugar and make it easy for you to make homemade water kefir. Our perfect mixture consists of 1 tbsp coconut palm sugar added first to the 1/4 measuring cup before adding the remaining cane sugar.
The sugar you put into your fermentation isn’t for you, of course, it’s for the cultures. So don’t be tempted to reduce the sugar content to make your water kefir healthier – you’ll only throw off the fermentation process. Remember, most of the sugar has been processed out by the time it is ready to drink.
On average, fermented water kefir contains the same amount of sugar as in 1 green apple – just 3 grams. If you add fruit juice to your fermentation, then the sugar content goes up to 5 grams. Not bad compared with the 72 grams of sugar in a Root Beer!
