It tastes natural and authentic, unlike many commercial kefirs. A fantastic product that I would highly recommend to anyone looking for high-quality, traditionally made kefir. Definitely worth it!

Customer photo review of Ki Kefir

Ki Kefir is our family's absolute favorite in London! My husband is very particular about the taste of kefir. Since we're from Central Asia, our gold standard is a light, thin, refreshing kefir that's closer to traditional ayran. Finding anything similar in London was tough, especially given I eat only organic. After trying everything available in the city, we settled on Ki Kefir — and it is simply the absolute best! We now order large bottles regularly and drink it every single morning as our main source of live beneficial bacteria. The kefir is incredibly delicious, always impeccably fresh, and the texture is right on point—light and smooth. A special treat is making fluffy pancakes with it; they turn out magical. And the service is top-notch: it's wonderful that the founder is always in touch and cares so much about product quality. We've fallen completely in love with Ki Kefir and are regular subscribers 🤍🥛

Ki Kefir

Store owner replied: Such a gorgeous review thank you so much Jasmin. We love that you are as passionate about it as we are. Plus beautiful pictures. I also add it to pancakes, great minds. Freya xx

Customer photo review of Ki Kefir

It truly is the champagne of kefir. My whole family fight over it, including my two year old who absolutely loves it. After struggling with IBS for years my stomach and immune system has finally settled and I feel Ki kefir really help play a part in that. I am 8.5 months pregnant and feel amazing knowing I am providing incredible nutrients to my baby already. Highly recommend!

Customer photo review of Ki Kefir

I've been really impressed with Ki Kefir. The flavor is fresh, smooth, not sour or sugary like some other kefirs I've tried. It tastes natural, with just the right balance of tanginess and creaminess. I also appreciate the quality of the ingredients and that it feels like a genuinely healthy choice without compromising on taste. I've noticed it sits well on my stomach and has become a regular part of my daily routine. Whether on its own, in a smoothie, or with breakfast, it's consistently delicious. If you're looking for a high-quality kefir that's both nutritious and enjoyable to drink, I definitely recommend Ki Kefir.

Customer photo review of Ki Kefir

I have been drinking Ki Kefir since I was seriously ill last year. I have noticed a massive improvement to my gut health, and I feel it has been a massive help towards my recovery. I have previously tried supermarket brands but they don’t compare at all to Ki Kifir. I have since recommended it to a few friends who have now also started drinking it.

Ki Kefir

An extraordinarily good product produced by a very customer friendly and responsive team. I have tried Kefir from numerous producers around the world, but this is truly unparalleled. Had issues with delivery in my area by APC, but this has been resolved with deliveries by DPD (who are also excellent in my area.) I would highly recommend!! Freya and Sam & the team have always delivered a fabulous product on time and regularly, and communication has been exceptional.

Ki Kefir

Store owner replied: Such a wonderful review, thank you Brad! We appreciate your constant loyalty and support... especially when delivery was a nightmare. Freya x

By far the best Kefir I’ve tried. It’s great having it on subscription so I never run out. So nice to have something taste so nice that’s actually good for you!

Ki Kefir

Store owner replied: Thank you Jennie for such a lovely review x

I look forward to my shot of kefir every day. It's so creamy and delicious and such a clean tasting drink. I'm sure it's helping my gut health. My dog absolutely loved it too and waits by her bowl until she gets some too!

Ki Kefir

Store owner replied: Thank you so much Nadir, we love that your dog is also a fan. Freya x

I love Ki-Kefir. Its the only brand that I prefer to my own home brew - I love the creaminess and slight fizz and the fact it is made from real grains and I know daily its making me feel better. Prof Tim Spector

Ki Kefir

Store owner replied: Thank you for all your support Tim!

Hands down, the BEST kefir there is on the market. I get a weekly supply in two gorgeous, large glass bottles. I really LOVE its freshness and the fact that there is no same old, same old, taste each week. Kefir has a "live" culture and the taste of Ki's kefir absolutely reflects that, unlike the bland supermarket-plastic bottle variety. Excellent product.

Ki Kefir

Store owner replied: Beautiful review thank you Kitty xx

I have been adding Ki Kefir to my breakfast daily and I know how beneficial it is, packed full of probiotics. It is natural and made the traditional way in small batches and without any extra hidden sugars or flavourings. I am not a milk drinker but I love this as a drink as I rather like the natural fizz from this ,most powerful and nutritious kefir. Thank you so much for making it and giving us a natural form of a probiotic.

Ki Kefir

Store owner replied: Thank you for your continued support Phillipa! Freya x

I really miss my daily kefir if away . This is the real product . I had tried other kefirs but nothing as good as this . Easy to drink Great in porridge and on cereals . I was delighted to find this after seeing it on Saturday Kitchen live a while ago . A very easy company to deal with , helpful and responsive I would thorough recommend this

Ki Kefir

Store owner replied: Thank you so much for the review Wendy. Ki x

I've been drinking Ki Kefir regularly for about a year now, and I absolutely love it! What I particularly enjoy is its distinctive, tangy, slightly cheesy flavour and natural fizziness. It tastes like genuine, traditionally fermented kefir, rather than just another yoghurt drink. I also really appreciate that it comes in glass bottles rather than plastic. I've enjoyed it so much that I now have a regular subscription, and it's become part of my weekly routine. I've also had a very positive experience with their customer service, who were helpful when I had a delivery issue. A wonderful product from a small business that I'm very happy to support. Highly recommended!

Ki Kefir

Store owner replied: Thank you so much for your review Chris. We truly appreciate all your support. Ki x

Ki Kefir tastes just like the kefir I used to make, not like the thick supermarket inferior copies! It’s one of my daily ferments and brings the fizz to my diet. Helping me to keep feeling like me!! Thank you team ❤️❤️

Ki Kefir

Store owner replied: We are so happy to hear this <3

I love ce kefir and have it when th homemade granola and fruit and yoghurt most mornings. It gives me a kick start to the day.

Ki Kefir

Store owner replied: Thank you so much for your review Sarah- the best start to the day I agree. Freya xx

There is Kefir, THEN , there is KI KEFIR - THE CHAMPAGNE OF KEFIR. This is truly exceptional no other Kefir comes anywhere near this. IT SPARKLES, IT TICKLES THE PALATE - IT IS TRULY IN DESCRIBABLE and anyone with a sense of what is phenomenal love this KI KEFIR. I buy only this and My doggies adore it and if I drink first they shout loudly at me. One can feel the love in this product and the health benefits are enormous - especially for the gut - the skin and the hair. I am addicted and have to stop myself from buying more - PEOPLE TRY THIS - YOU WILL LOVE IT IMMENSELY and the makers are DELIGHTFUL PEOPLE WITH TREMENDOUS INTEGRITY - one can taste all that in every sip of KI KEFIR!!!!!

Ki Kefir

Store owner replied: Emma what a GORGEOUS review, thank you so much. It is customers like you that put the biggest smile on our faces. My dog and toddler both love it too. hehe. Freya xx

I’ve been a customer for around six months now and I honestly can’t recommend ki kefir enough! I had a brief two-week break over the summer while I was away, and I really noticed the difference. I couldn’t wait to get home and start having it again! Since making kefir part of my daily routine, I feel so much healthier and more energetic, and just generally better in myself. After noticing how I felt during those two weeks without it, I’m definitely converted. It’s now a firm part of my routine and something I look forward to every day!

Ki Kefir

Store owner replied: Thank you Elizabeth for such a lovely review. We are so happy to hear that its helping you feel more energetic and overall healthier. Freya xx

I look forward to my morning « shot » of Kikefir every morning - I pour it over my bowl of oats, fruit and homemade granola instead of yogurt which I was finding too heavy. I use it alongside a little rice milk (that the oats have soaked in for about 20 minutes) and find it much more digestible than cow’s milk and yogurt but still giving me the benefits of pro biotics and calcium - plus I love the taste (even when it’s gone a bit tangy) - so much better than brands I have bought in the supermarket. We’ve had a few hiccups along the way with deliveries but the Kikefir team has been very proactive about sorting them out and I wish them all the best going forward

Ki Kefir

Store owner replied: Thank you Alison for such kind words! We love having you as a loyal customer and appreciate you sticking with us whilst sourcing an external delivery company that works for you. Freya xx

Ki Kefir is such a BIG part of my life that our fridge looks incomplete without their lovely large glass bottles, brimming with amazing goodness, taking front and centre stage every week! What I LOVE the most about Ki Kefir is that it tastes so authentic. The other kefirs that I have tried - usually in plastic bottles (ugh!) always taste the same, every single time. But with Ki Kefir, each week can be different because of the content's sensitivity to environmental factors. I have kefir with cereal, use it as a smoothie base, and sometimes just drink it after exercising as it is utterly refreshing and nourishing. As for the support and customer service - they are second to none. However, as the delivery is so smooth and seamless, it is rare that you need to reach out to them. I cannot recommend Ki Kefir highly enough. I know that it has greatly improved my gut health and overall immunity.

Ki Kefir

Store owner replied: Kitty, thank you so much for such a wonderful review. We are so fortunate to have incredible customers who share the same passion as us. The Ki Team xx

I’ve said it before, but I’ll say it again. This is the best Kefir I have ever tasted. I suffer with Diverticulitis and have not had a single episode since I started with it. It is also the most palatable Kefir I have ever tasted. The team at KiKefir are very pleasant and amenable to anything you may have a problem over, and will do their best to solve it. An example of this is, I periodically need a delivery by Pedal Me, which is for the London area, and they will arrange this. Please, whether you are suffering with Diverticulitis or not, give this product a go, and feel the benefit Kefir can give you.

Ki Kefir

Store owner replied: Hey Patricia, thank you so much for taking the time to write such a wonderful review. We really appreciate it. The Ki Team xx

My Kefir arrived right to my door, which was amazing as I thought I’d have to collect from our mail room. It was perfectly packaged and is the smoothest, tastiest (real) kefir I’ve had!!! Thank you Ki, I will definitely be recommending.

Ki Kefir

Kefir by KiKefir is high quality, made of organic milk and has a great taste. It is a proper kefir that has only 2 ingredients: milk and bacteria which is necessary for the gut health. No artificial additives unlike in many supermarket brands. It really helped me with maintaining healthy diet, I always look forward to KiKefir delivery. Additionally, great customer service , where you actually get the response from a person, not AI agent. Highly recommended

Ki Kefir

Store owner replied: Yes, I am most certainly a human and not Ai :D Thank you Anna, for such lovely feedback! We really appreciate your custom and are over the moon to hear how happy you are with our product and service. Many Thanks, Jess at Ki

Ki kefir is the best tasting kefir that I’ve tried. Not only that but it is a small (helpful and friendly) artisanal team using whole milk from grass fed cows, from small farms. It’s in glass bottles, not plastic. I use the bottles as water bottles I the house and give them to my local ‘fill your own packaging’ shop.

Ki Kefir

Just the best kefir ever! It's helped me with digestive issues so much, post-treatment for SIBO and H pylori, and my gut is now in the best shape it has ever been. It tastes delicious too! 100% recommend to everyone!

Ki Kefir

Store owner replied: Such a glorious review, thank you so much Melissa. Our aim is to help as many people as possible and I personally agree, I was in the same boat as you and now my gut is in the best shape its ever been. Freya xx

Delicious and great customer service. Do love this lot and appreciate the use of local milk

Ki Kefir

Store owner replied: Thank you so much for your review Rachel, we really appreciate it. xx

If I remember rightly I heard about Kikefir on Radio H-P. I used to have a kefir culture, making my own kefir which was always a bit hit and miss, and anyone I asked to look after it when I went away went into a blind panic; so I gave up and started buying rather tasteless, bland kefir from the supermarket. Kikefir is a whole new ball game with a lively refreshing taste and I am convinced that my daily shot which I tend to add to my breakfast granola and fruit bowl every morning is beneficial to my digestive system which tends to be pretty sensitive. I am so grateful to Sam and Freya for developing this product and for persevering with the issues we have had with deliveries to my address - it seems so unfair that a small business like Kikefir is at the mercy of big delivery corporations who don’t fulfill their commitments. I wish Kikefir every success in the future for their delicious and superhealthy product.

Ki Kefir

Store owner replied: Thank you so much for such a gorgeous review Alison and your continued support, it means the world xx

I love the taste. Lots of kefir can be quite overpowering but it has a very subtle tang which I love. I also like that it’s fresh, in a glass bottle and hasn’t sat on a supermarket shelf forever. The subscription model works perfectly so I never run out

Ki Kefir

Store owner replied: Such a lovely review thank you Jennie. We are so glad you are happy with all aspects of it xx

I’ve been using this product for a while now and it makes a massive difference to me - highly recommended!

Ki Kefir

Store owner replied: So glad its making a difference Phil! :)

We discovered Ki through Natoora. Having tried kefir from supermarkets, we were blown away by the taste of Ki. We drink it daily and are never disappointed. The delivery process is also second to none, with fantastic packaging and (in Pedal Me) the friendliest and most effective delivery riders we have ever encountered!

Ki Kefir

Store owner replied: Such a gorgeous review thank you Callum. We are also so happy to hear how excellent Pedal Me are- we totally agree. x

I love Kikefir. It is the best kefir on the market. I love that it is small batch produced - much better than the stuff you buy in the supermarket.

Ki Kefir

Store owner replied: Thank you so much for your review Olivia, we really appreciate it x

I order it about once every six weeks and it lasts for about 2/3 weeks. I like its fresh flavour and smoothness. I have not noticed any changes as a result of taking it but I didn't particularly expect that. I know it is helping my microbiome

Ki Kefir

Store owner replied: Thank you for your review John :)

To put it as delicately as one can, Ki Kefir keeps me “regular”. I love its gentle effervescence and sharp flavour. Unfortunately, we have moved to a house that has no place to leave deliveries, but I am happy to go out of my way as I now do to buy it.

Ki Kefir

Store owner replied: Thank you for your continued support Diana xx

Really happy I found Ki Kefir - organic, healthy drinks which have improved my digestive system. Thank you!

Ki Kefir

Store owner replied: Thank you so much for your kind words Anna xx

I love Ki, it’s definitely the best Kefir out there without a doubt! I originally started drinking it about 5 years ago because I would randomly get very heavily bloated for no rhyme or reason and couldn’t figure out why. I then started drinking Ki Kefir and it really helped, now I very rarely get that same painful bloat anymore! I also drank it all the way through pregnancy and whilst I have no idea if it’s related, I never got any morning sickness and I can’t help but feel that having a healthier gut helped play a little part in that. Thanks Sam and the team, you’re brilliant! X

Ki Kefir

Store owner replied: Thanks so much for your continued support Laura, it means a lot! We are so glad it's helped. xx

I love Ki Kefir ❤️

I suffer with diverticulitis, and since I have been taking Ki Kefir, I have not had a flare up. I drink it before I have anything to eat in the morning. I have tried other makes and they are just too thick and take a lot of getting down. With KiKefir I find that it is palatable and delivery is every Thursday for me, so that I don’t have to wait in several days for a delivery. All in all, it is working well for me keeping the diverticulitis at bay, and I am pleased that I found about it from reading a magazine article.

Ki Kefir

Store owner replied: Such lovely words thank you Patricia. We are so pleased that it has been helping your flare ups. Ki x

I have an autoimmune condition and looking after my gut health is incredibly important in managing my condition and reducing inflammation. My skin has been cleared and I've had so much more energy since I started drinking Ki 12 months ago. I love it!

Ki Kefir

I started using ki kefir last year . Going through the menopause created a few health problems especially with my digestion. I spoke to Sam who advised to start with a small shot of kefir and gradually increase . I have found my digestion is much improved. I have also noticed improvement with my skin too.
