  1. Probiotic Potential:
    • A study published in the journal Food Microbiology explored the microbial composition of water kefir grains and found a diverse community of bacteria and yeasts, suggesting potential probiotic effects (Gulitz et al., 2011).
  2. Antimicrobial Properties:
    • Research published in Journal of Food Protection investigated the antimicrobial activity of water kefir against foodborne pathogens. It highlighted the potential of water kefir to inhibit the growth of harmful bacteria, indicating its possible role in food safety (Garofalo et al., 2015).
  3. Health Benefits:
    • A review article in Frontiers in Microbiology discussed the health-promoting potential of kefir, including water kefir, attributing benefits to its probiotic properties and potential impact on gut health (Marsh et al., 2014).
  4. Nutritional Analysis:
    • Another study published in International Journal of Food Sciences and Nutrition provided a comprehensive nutritional analysis of water kefir, highlighting its vitamin and mineral content, which contributes to its potential health benefits (Rea et al., 2018).

These studies collectively suggest that water kefir may offer probiotic effects, antimicrobial properties, and nutritional benefits, making it a potentially valuable addition to the diet. Always ensure to check for the latest research and consult with healthcare professionals for personalized advice.


While organic water kefir offers numerous health benefits, it’s important to enjoy it:

  • Moderately: Despite fermentation, organic kefir retains some sugar. Consume in moderation as part of a balanced diet.
  • Occasionally: To manage sugar intake, it’s recommended to enjoy organic water kefir a few times per week.

    Hi there I bought some of your water kefir grains. First attemp .First time I follow the instructions but only I finished drinking it instead of throw it away Second preparation after 48 hours it tastes the same as the first (I used bottle water and brown sugar) Third preparation I decided to add a fig. I checked after 24 hours and I found some “white stuff floating” I can see now the grains got bigger but I am concerned about that “white stuff floating” Is it still good for drinking or did I do wrong to put a fig and I need to thro everything away?

  2. Anita says:

    Your drinks are delicious. However I have read that water kefir grains contain yeasts – please can you tell me if I should avoid these while I have candida overgrowth or whats sometimes known as SIBO? Thank you

    1. Freshly Fermented says:

      Hi, sadly we are unable to give you any medical advice. There is some evidence to show that SIBO can be aggravated by water kefir.

  3. Stephanie says:

    Hi – I don’t normally tolerate sugar, does this fermenting process change make the sugar more digestible, less bad for you? Thanks

    1. Lisa Hillyer says:

      Hi, this will produce a low sugar drink but there is sugar still present so if you are unable to tolerate sugar then this probably won’t be the best thing for you. Have you thought about milk kefir or coconut milk kefir?

  4. Aleksandras says:

    Hi, I was wondering if “burping” your water kefir would count as opening the bottle and if that would interfere with it’s 30 day shelf life in the fridge after it’s second fermentation, thank you in advance!

    1. Freshly Fermented says:

      It would count yes. Generally, if a fair bit of air gets in, then fermentation happens and you will end up with vinegar. For that, you would usually need to drink some after opening to free up some space in the bottle for oxygen to fill. Just burping won’t cause issues but can lead to flat water kefir in the long term.

  5. Frances Pace says:

    Hi – I have a dairy allergy – have the grains been in contact with dairy at any point in their journey to me? How are they actually made? Thanks!

    1. Freshly Fermented says:

      Hi, we have a strict allergen policy and these are manufactured in a separate unit to dairy and wheat

  6. Chad Boath says:

    I orderedwatergrains instead of milk grains. Can I use them with milk instead.?

    1. Lisa Hillyer says:

      Hi Chad, no you can only use water with water kefir grains as the milk will kill them. Thanks Lisa.

  7. Shaun says:

    Hello, I want to order but it seems you don’t ship to Hong Kong. Anyway I have a question about the water kefir grains. Where do you harvest them from? I’m curious as to their origins

    1. Lisa Hillyer says:

      Hi Shaun, we ship anywhere in the world so if you are having an issue placing an order please email us on and I will help you with that. We manufacture our water kefir and have done for the last 5 years so it’s grown on site here with us. Thanks Lisa.

  8. Aleksandras says:

    Hi, I have a couple of questions. You mentioned in your description that “as long as you look after the culture, it will produce water kefir indefinitely” and I wanted a bit more clarity on this. Does this mean I would only need to buy water kefir grains once and keep it forever as long as I take good care of it or will there come a point where I would need to change them? Also in additional information it says that the shelf life of the kefir grains is from 15-21 days. Now is this before activating them or is this the typical range that you are expected to be able to reuse them until you have to replace them again? (This links back to the first question). Last question being, it was said that the kefir grains would start growing. Do you try to keep them at their original size by discarding some of it from time to time or do you let it grow indefinitely? Thank you so much in advance.

    1. hungrycloud says:

      Hi, they are a living product. They can survive out of sugar water for 21 days. That is why we add a date, it’s a shipping best before. As long as water kefir is kept above 20c and receives regular changes it will multiply and grow. As long as you don’t neglect it, you will never need further grains from us. Our original batch of grains is still going strong after 5 years!

Not good

This the 2nd time I have ordered from your company. The last time I had to call up and get a replacement of the kefir water grains as they were not active (which you had no problems with sending me a new pack, which then worked correctly) . Now this time I received the grains , activated them on the same day they were delivered. I followed the instructions on your website and they appear to be dead too. Very disappointing as I want my kefir drink . I will have to make a call.

Water Kefir.

Am a beginner to this - have followed all the instructions and am starting to get some good results although still having inconsistent results with the second fermentation producing enough carbonation.

Gill Peacock
Great grains!

This is my second time trying to ferment water kefir. Found the video really helpful and am now happily fermenting lots of water kefir.
It actually took me 3 weeks to adjust to it - lots of burping and mild diarrhoea - very nearly gave up but now don't have any problems at all so if you're experiencing the same, stick with it!

work in progress

I got my last grains from Germany and they really took off really fast. used them for 2 years and gave away almost 100 gr every week. then I left them to die in the second winter. :(
These , so far, nothing. No growth, no fermentation, no bubbles. Will start yet another process today, and hope they will do it this time. It is just a matter of time, I am sure I will get them activated, just wondering why these are so different

Busayo Odelola

You were too late in delivering this.Had to use extra cost to send abroad.
