it was a tablespoon size quantity and it rehydrated really quick but it has idk what in it. i saw a hair after it had already hydrated and some miscellaneous black specks as well. I haven't done anything else with it yet so idk how they'll produce

Originally bought some grains from Amazon and despite lots of effort, could not achieve carbonation or a decent drink. Eventually I binned them and ordered from here and difference was night and day! Beware the second ferment with these grains as they are so active they burst open a plastic bottle. They produce lovely tasting water kefir and after a week I've had to buy a bigger jar as they are growing so fast. Absolutely top quality grains. Thanks!!

Hi David, we're thrilled to hear you’re enjoying our kefir grains and that they've made such a difference! Thanks for sharing your experience, and happy fermenting! 😊

This was my first time making water kefir and I followed the instructions exactly. I was really pleased with the results from the very first batch. After making a few more, I realised that fermenting for 24 hours at each stage gives me the flavour I love.

The instructions suggest 48 to 72 hours for both the first and second fermentations, but I’ve found that a 24 hour first ferment followed by a 24 hour second ferment works perfectly for me. I think this mainly comes down to home temperature, as warmer homes seem to speed up fermentation.

I’m so glad I went with this seller. The grains activated beautifully, worked exactly as they should, and gave consistently great results. I’m genuinely delighted and would happily recommend them.

These water Kefir grains are so good! I've bought some live ones before from another well known company and they just didn't work but these are amazing. Instructions were very clear and made the perfect naturally fizzy fermented drink. Just to note, I used raw honey instead of cane sugar in the same quantity and it worked perfectly. Thanks so much!

I did exactly as instructed and my kefir has not become active.

Haven't made the water Kefir yet, but from a marketing/pr/advertising point of view and being the consumer it ticks all boxes in terms of packaging, simplicity and also the way in which the instructions are delivered. But that's maybe because I'm an absolute papyrophiliac!

Have been really enjoying making my own water kefir at home. The culture was really easy to rehydrate and it's been really active from the start - would definitely recommend.

I got these and have a batch fermenting right now. It’s the first time I’ve used kefir grains and they seem to be working well. The instructions were clear enough even for someone doing it the first time. Just a note to US customers, the shipping can be slow. They finally arrived nearly a week after the estimated arrival date. So if you need them right away these may not be for you.

Hi Galen, thank you for your kind words and for sharing your experience! We're glad to hear your kefir grains are working well and that the instructions were helpful. Regarding shipping, sometimes packages can be held up at US customs during busy periods, which can cause delays. We appreciate your patience and hope you enjoy your fermenting journey with Fizzy Buoys!

FAQs

What are water kefir grains?

Water kefir grains are cultures of beneficial bacteria and yeast we sell dried or fresh. Fed with sugar water, they become active and can be used to make water kefir repeatedly.

How will my water kefir grains be delivered?

Your grains will be delivered using Royal Mail 48 hours Tracked. They will be posted through your letter box with an easy-to-follow recipe and instructions.

Do I need to activate my water kefir grains straight away?

No! You can purchase our dehydrated that can be activated whenever you want to start making your Kefir Soda. This is also great if you're looking to purchase them as a gift. If you want to start brewing straight away - buy our fresh grains.

How often can I reuse the grains?

Water kefir grains are reusable indefinitely when properly cared for. Simply transfer them into fresh sugar water after each batch.

How long does it take to rehydrate dehydrated water kefir grains?

Dehydrated water kefir grains will take around 3–5 days to rehydrate and become active. Fresh grains are active from your first batch.

How do I know if my grains have rehydrated successfully?

Healthy grains typically become plumper, more translucent, and begin fermenting sugar water. It may take a few brewing cycles before they perform at their best.

My grains aren't producing bubbles. Are they dead?

Not necessarily. Newly rehydrated grains often need a few batches before becoming fully active. Also, most carbonation develops during the second fermentation in sealed bottles, not during the first ferment.
