Bottling Water Kefir

Bottling Water Kefir | Water Kefir Expert Advice | Cultures for Health


Water kefir is a great fermented product for beginners and makes a delicious replacement for soda. It’s easy to make and can be flavored with fruit or juice and bottled to produce a lightly carbonated probiotic beverage. This flavoring and bottling period is called the second fermentation, as sugars from the flavor additions feed the bacteria, allowing more fermentation gases to be produced, and resulting in a fizzy finished product.


Equipment and Ingredients:


Bottling Instructions: 

  1. Check the bottle for cracks prior to use, as cracks will weaken the integrity of the bottle. 
  2. Add desired flavoring to the bottle.
  3. Fill bottle with water kefir, leaving about 1 inch head space.
  4. Close the bottle securely and let sit at room temperature for 24-72 hours.
  5. In warm temperatures, burp the bottles once per day, to avoid excessive pressure build-up.
  6. Place the bottles in the refrigerator, if a cold beverage is desired. 
  7. Use caution when opening the bottles. Contents are under pressure.
    • We suggest placing a towel over the top of the bottle and apply downward pressure on the cap while opening the bottle, to minimize fountains of water kefir or flying bottle caps. Open over the sink or outside.
