I purchased the kefir making kit online. It’s so easy to make! And the grains are top quality. As I don’t live in the area, I can’t purchase products directly but this is a perfect alternative

KiKefir is really delicious- it’s the best I’ve tasted & I’ve had a lot of Kefir! It has excellent provenance with milk supplied by Hook Dairy.

Sam is extremely knowledgeable and generous with her advice. Looking forward to making my own kefir with renewed confidence after a brilliant workshop.

I have been using Ki Kefir for 4 months now. I originally didn’t believe it could have the effect that it did. I suffered from severe eczema and gut health issues and ever since I have been using Kefir I haven’t had any eczema, and my gut has been better than ever, even when my diet isn’t up to scratch. I swear by this product and especially this brand as it is better than any other kefir I have previously tried.

Ki Kefir produce the ‘real deal’ kefir! I love the natural fizz and flavour. When I found Sam via a mutual friend a few years ago I was so happy to have finally found the best kefir ever. I eagerly await my delivery of 4 bottles delivered to my door every month…often with the bonus of a lovely chat with Sam :-)

Just discovered this brand of Kefir, a tasty miracle food that is way beyond any other taste of kefir I’ve had which is fantastic given all its health benefits! Fast reliable delivery right to my door too .

Sam and your Ki Kefir company I salute you! After a labour of lockdown self love I've tried making it all - sourdough, kombucha (boo chi), kimchi, kefir water, coconut kefir the lot lol. And can hand on heart say this is the best tasting, most nutritious, well made, personally delivered - diverse delicious probiotic Kefir milk on the market! I've hung up my wooden spoons and am content to leave the passionate alchemy to you and reap all of the gut bacteria benefit from your exquisite elixir. Thank you for your nourishment and kind caring customer service. All the best <3

My absolute favourite! The best taste, and I love how it reminds me of my childhood.

I cant tell you how much this has helped me . Plus it’s so nice to have such warm and friendly customer service . 5 star service and quality all round!

Within only a month of using Ki Kefir I noticed a huge difference to my gut health and digestion. Now it’s a part of my daily routine and I really can’t imagine life without it. This product had been highly recommended to me and now I know why. Excellent service, communication and results.

Super delicious Kefir, great for your gut health and in eco-friendly recyclable bottles! My mum and I both love it!
June 5, 2019
Best kefir i’ve ever had! Feel so much better in myself after my morning dose, couldn’t recommend more!
June 5, 2019
Love Ki kefir. It’s the best kefir I have tasted in comparison to any other brands. It taste how kefir is meant to, creamy and tart. I can’t get enough
June 5, 2019
The best kefir I've had by miles. Tastes delicious and really helps my IBS. Highly recommend!!
June 5, 2019
It tastes equally as good as it looks! Love the design n how it feels in my belly. Good for the gut. Closest I can get to my Scandinavian Piimä ;) !! Yammy!

Ki Kefir is so smooth and creamy, it’s obvious the quality of the ingredients that go into making it. It’s much nicer than other mass-produced brands which I have tried over he years. Also love the plastic free packaging as well with the glass bottles, which can be handed back and reused for your next weeks supply. Having had problems with my skin and other related inflammation issues over the years, the difference I have saw from focusing more on my gut health has been amazing. KI customer service is really helpful and have given me so many tips over the years on what to focus on. One of the reasons I love and have stayed committed to this brand!

About a year ago I started trying to improve my gut bacteria. The pills were a waste of money and the fermented sauerkraut didnt seem to do much. The supermarket kefir was tasty but otherwise not great. Ki Kefir is fantastic. It settles my stomach and with regular use has probably contributed to the huge improvement in my digestive tract. It is now a big part of my daily routine.

Magic in a bottle! It's easy to fall in love with Sam's Ki Kefir- you can taste the quality of the product and they come in glass bottles which you can reuse and recycle. Have noticed positive changes to my gut health and so have friends and family whom I've introduced it to. This was not the case when I bought other brands from the supermarkets. So happy with product and to be able to support a local business- highly recommended!
May 28, 2019
Amazing homemade, quality Kefir. Ki Kefir offers personable service and is run by helpful, lovely people!
May 26, 2019
Ki kefir is unique - you definitely can’t get kefir like this in the shops! I love the zingy flavour that really gets you going in the morning. I’ve had it straight from the bottle, made overnight oats with it, had it on cereal and I’ve even baked with it. It’s delicious and versatile! My partner and I are both hooked!

I usually work away and a few years ago I suffered with unwanted weight loss, flue and noticed I had low energy (which is extremely important for my job) due to the low quality foods provided whilst away. So having researched and visited my GP, poor Gut Health was a possible very likely cause of all this. So three months prior to leaving for the next trip I had Ki Kefir daily which helped repair my gut and maintained my good health for the 6 months away. I’m so happy I found the product, I’ve just got back so time for a top up. Thank you Ki Kefir

I was first introduced to Kefir when suffering with a mild form of IBS, so I started out by trying lots of brands available in London. Many are good but I can honestly say I had the best results from Ki. They have a stronger product which tastes great, I'm getting exactly what I need/want with Ki, they use recyclable materials, have an excellent door to door delivery service available and their Ki Kefir comes in too sizes, I like to get the 750ml for my cereal/smoothies etc very cost effective. A cup a day has totally improved my gut health, which has reflected majorly with positive and consistence changes in my energy levels, abdominal bloating and skin. Highly Recommended!

BEST QUALITY Kefir on the market that works wonders on your belly and MOST FRIENDLY and PERSONALIZED service with delivery to your door! Love Ki Kefir!
