FRESH GRAINS. A NEW KITCHEN RITUAL.
These grains arrive fresh, not dehydrated. Feed them cane sugar and water, then reuse them for your next batch. Flavor your finished kefir your way.
Refrigerate on arrival and feed within 24 hours. Dissolve 2 tablespoons of organic cane sugar in 3 cups of water; cool to room temperature before adding the grains.
Cover with butter muslin and a rubber band. The fresh-grain guide calls for 2–3 days of culturing. Do not leave grains culturing longer than 72 hours.
Strain the grains into fresh sugar water for another batch. Flavor the grain-free kefir with fruit if you like, following the guide, then chill and enjoy.

United StatesSo much better than dehydrated grains! They are healthy and multiplying.
United StatesI had posted 2 comments earlier about a strange taste. Then there were gummy strings floating in the water. I sterilized a new mason jar and transferred the grains to the new jar. After about a week, the grains are doing well, and the taste is normal. The weather has been variable, very hot one day and cold the next but that has not affected the brewing. My old grains started up again, so now I have two jars of kefir water brewing. and they are used up quickly.
It sounds like you've been through quite the kefir journey, Susan! We’re so glad to hear that your grains are thriving in their new jar and that the taste has returned to normal. Variable weather can sometimes affect the brewing, but it's great to know it hasn’t been an issue for you. It’s fantastic that you’ve got two jars of kefir water going strong now. Keep up the great work, and if you need any more tips, we’re here for you!
United StatesI’ve only just made my first activation, so it’s too early to tell whether or not they’ll grow. I do prefer it this instead of the dry grains I previously bought from you.
United StatesThe new batch I ordered came with a strange smell, was gummy, and the entire jar was full. It still has a vinegar taste and smell. I will give it several more weeks. I am using organic cane sugar. I have been drinking it with no ill effects. Have you changed the water kefir grains? What do you mean by a break. I believe you are referring to the new grains I ordered. Thanks for your help.
Thank you for reaching out to us, Susan! We're sorry to hear about the issues you're experiencing with your new batch of water kefir grains. We haven't made any changes to our grains, but it's possible that a break-in period might be necessary. By "break," we mean allowing the grains time to adjust and start working optimally. The strange smell and gumminess could be due to a temporary imbalance. Ensure you're using Spring bottled water and maintaining the right sugar-to-water ratio. It's great that you're not experiencing any ill effects, but if the problem persists after a few more weeks, please let us know. We're here to help!
United StatesThis is my second order of Endless Water Grains. After I year of wonderful kefir Wate, I went on vacation, put it in the fridge and forgot it. When I started it again the grains didn't grow very well, but they were eating the sugar. So, I decided to get a new batch. Everything was going well after a few days with the new batch, but the taste was different, and I didn't like it. I hope after a few weeks it will change. It was sent when the weather was hot and there were many more grains in the jar than usual. I have been making Endless Kefir Milk successfully for several months. I also use many of their cheese products successfully. The buttermilk is easy to make and is fantastic. Now I will save money on buttermilk. I used in baking said bread. This company is great.
Thank you for sharing your experience with our Endless Water Kefir Grains, Susan! We're glad to hear you've had a year of wonderful kefir and that you've enjoyed our other products like Milk Kefir and cheese cultures. It sounds like you've become quite the fermentation expert! Sometimes, water kefir grains can take a little time to adjust after a break, especially if the temperature changes during shipping. We're hopeful that the taste will improve as the grains adapt to their new environment. If you have any concerns or need further assistance, please don't hesitate to reach out. We're here to help!
One jar of Endless® Fresh Water Kefir Grains and instructions. Sugar, brewing jars, thermometer, cover and strainer are supplies you provide.
Refrigerate immediately and feed within 24 hours, as directed in the fresh-grain guide. These are fresh grains, not a dehydrated starter that needs a dry-grain activation routine.
Dissolve 2 tablespoons organic cane sugar in 3 cups water. Cool to room temperature before adding the contents of your grain jar. Never add grains to hot water; the guide says no higher than 90°F. Cover with butter muslin and a rubber band, and culture for 2–3 days.
Yes. Strain the grains from finished kefir, place them in fresh sugar water and repeat the guide’s feeding steps. Continued use depends on feeding and care; this is not a limited-reuse powder.
The fresh guide calls for 2–3 days for the grain-containing batch. At 24 hours the drink may still be sweet. Do not leave the grains culturing longer than 72 hours. Optional fruit flavoring adds another 24 hours after removing the grains.
Strain out the grains first. The guide uses fruit and a cloth-covered second jar for 24 hours, then chilling. If using a cap or lid, it says to release pressure at least every 12 hours. Use pressure-rated bottles for carbonation and follow the guide; pressure can build quickly.
Organic sugar and live active cultures. Manufactured in a facility that processes products containing gluten. Labeled Non-GMO. This is not a claim of certified gluten-free or allergen-free production.
Organic cane sugar; water free of chlorine and fluoride; two quart-size glass jars; butter muslin or a coffee filter; rubber band; thermometer; mesh strainer; and a stainless-steel, silicone or wooden spoon.
Refrigerate fresh grains when not in use and use by the date on the bag. For feeding and ongoing care, follow the included fresh-grain instructions or ask our team.
Read the Endless® Fresh Water Kefir instructions. It is specific to these fresh grains, rather than the dehydrated product.
