The story
About Matcha & Mint
An uplifting, aromatic herbal fusion. Brewed with premium organic matcha and cooling mint, this refreshing beverage is rounded out with a hint of lime for a perfectly balanced flavour.
Water kefir is a traditional fermented drink, made with a living kefir culture rather than milk.
Raw, living, hand-fermented
How every bottle 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.

How long does PiQi keep?
Unopened, PiQi keeps for up to 120 days in the fridge (see the date on the bottle). Once opened, the 480ml screw cap keeps it sparkling for 3–5 days.
Why does it need to be kept chilled?
PiQi is raw and never pasteurised, so the live cultures stay alive. Keeping it below 5°C keeps it fresh, gently sparkling and tasting just as we brewed it.
Is water kefir 0.0%?
Not quite. Like kombucha and all naturally fermented drinks, PiQi contains a trace from fermentation: under 0.5% ABV.
Is PiQi vegan and organic?
Yes. PiQi is dairy-free and vegan, and certified organic by OF&G. We brew it in small batches in Devon using organic ingredients and our vegan water kefir culture.
How is it delivered?
Delivery to mainland UK is included on every case. We brew to order and ship Monday to Wednesday in a recyclable insulated box with ice, so it arrives cold.
Can I change or pause my subscription?
Of course. You can skip a delivery, swap flavours, change how often it arrives or pause at any time from your account.
