70%
Made with mother culture
Did you know that around 70% of your immune system is found in your gut?
Every bottle starts with our mother culture: glassy little water kefir grains, alive with bacteria and yeasts. We feed it, keep it warm and strain it after every batch, and it grows a little each time.
We never pasteurise, so the cultures are still alive when you pour.

From culture to bottle
How PiQi is made
Water kefir is a traditional fermented drink, made with a living culture rather than milk. Here is how we make ours in small batches in Devon.
-
01
Start with the culture
Our living kefir culture goes into triple-filtered water with organic sugar and organic figs.
-
02
A warm, slow ferment
It rests in our warm fermentation room for about two days while the cultures feed on the sugar.
-
03
Strain and save
We strain out the kefir grains and keep them for the next batch. They grow as they ferment, so the culture lives on.
-
04
Add the fruit
A second ferment with organic fruit, juices and herbs, like fresh lemons and raspberries, gives each flavour its character.
-
05
Bottled raw
Bottled and kept chilled, never pasteurised, so it reaches you raw and alive.
Never pasteurised, so the cultures are still alive when you open the bottle. Keep it chilled.

I love the ginger and lemon, also the raspberry. Nutritious drink, I am always ordering them. So good!

Loving my new hobby!
I couldn't be more pleased with my kit, I got stuck in the moment the box arrived. I was also gifted some figs and personal note which I thought was such a classy touch. Would highly recommend PiQi Life for all of your Kefir needs.

TRIED FOR THE FIRST TIME AND LOVED IT!!
Purchased in my gym / club to try and really refreshing and you can taste the subtle fig which I was dubious about! About to buy a case to stock up. Please stock on Ocado! Never like buying drinks that have sugar but I think this is the exception!! Lovely!!!

Can’t get enough of this fermentation kit
I absolutely love it, I’m already on my third batch since getting my fermentation kit and it tastes fantastic. It’s also so much fun. I’ve been experimenting with different flavours and honestly, there are no wrong ingredients.
My absolute favourite is ginger + lemon, and the next one is basil + raspberries. For people who love experimenting and being creative, it’s a brilliant gift idea.

Lovely kit to get started
I ordered this kit whilst on annual leave after a tough few months at work where I was close to burnout and had zero energy left.
It's so easy to follow the instructions included with this kit and minimum effort for delicious healthful results!
The relaxing hobby I was after!
Would recommend as a gift (to yourself or someone else), as the personalised hand written message and figs thrown in make it feel extra special.
So far I have made this with the 2nd ferment with fresh ginger and leaving it the extra time to fizz as directed in the instructions and it is sooo delicious.
Current version is in 2nd ferment with ginger and green cardamom.

Being alcohol free, these gorgeous ferments are my go to when I want to add a little sparkle to my day. Perfect at any time, they feel luxurious, refreshing and put a little pep in my step. My self care in a bottle.

Complete Water Kefir Kit - brilliant!
I am so happy I bought the kit and not not just the grains - it meant I had everything I need in one delivery to start my fermentation right away! But the best part is the customer service I have received - every one of my questions has been answered (via email) and after being so nervous about messing the process up, I'm now on my third ferment and feeling confident in what I'm doing! Thank you for all the help PiQi.

Our story
Rooted in craft, fermented for life.
We're Aksana and Nick. We started PiQi in our London kitchen in 2021, and now hand-craft every batch at Venn Valley, a hub of artisan producers on a vineyard in Devon.
We use only organic ingredients and glass bottles, ship in paper-based insulation, and compost our waste on the vineyard. Small batches, slow fermentation and nothing artificial.
Fermented beauty
Kefir for your skin, too
Our handmade soaps are made with fig-infused water kefir, olive oil, coconut oil and shea butter. Palm-oil free, vegan and gentle on every skin type.
