PASSEDWhat is water kefir?
Water kefir is water fermented with water kefir grains, dried fruit and flowers: probiotics you drink. It tastes lightly sweet and tart with a fine natural fizz, and is very refreshing ice-cold. Like kombucha it is fermented, but not from tea: no caffeine, just a gentle tang.
BlueberryOsmanthusStrawberryMany lactic acid bacteria and yeasts ferment it together, and it stays cold all the way, so the cultures are still live when you open it.
After a meal, or whenever you want a drink.
Fermented in water, not tea: for vegans, adults and kids alike.
Only water, organic cane sugar, dried fruit and flowers. No preservatives, flavorings or sugar substitutes; kept cold all the way, it keeps for 35 days unopened.
How it’s made
Two fermentations over 60 hours, as lactic acid bacteria and yeasts slowly turn fruit-and-flower water into a lightly tart, lightly sweet drink.
Hours 0–24
Pure water and organic cane sugar with clear, crystal-like water kefir grains. The grains eat the sugar and ferment it slowly.
Hour 24
The grains are strained out and kept for the next batch, so there are none in the can.
Hours 24–60
The dried fruit and flowers go in for another 36 hours, bringing fruit, floral notes and a gentle tang.

Strawberry: strong fizz, tasty.8*****u · 2025.12.07
Like drinking soda! Lots of bubbles and so good. It can replace sparkling water.p*****w · 2025.12.03
Upright, at the back of the fridge. No more than 2 hours out of it: warmth speeds up fermentation and adds fizz.
The fine bubbles come from the live cultures. Chill it well, don’t shake it, pull the tab slowly and pause at the hiss to let the bubbles settle.
330 ml is just right for one go, and it tastes best cold.
They come from natural fermentation: a sign the cultures are alive.
Drink it by that date; it gets more tart and fizzy as the date nears.
The osmanthus flavor contains mango. Made in a facility whose equipment also handles milk.

FAQ
Both are probiotic drinks fermented with kefir grains. Milk kefir is fermented from milk and is thick like yogurt; water kefir is fruit-and-flower water fermented with water kefir grains: light like a fruity sparkling drink, and vegan. If you like it light, or eat vegan, choose water kefir.

Blueberry is fermented with dried blueberries, apple, raisins, roselle and chrysanthemum; it is the best seller, 36 kcal a can. Osmanthus uses jasmine, rose, osmanthus and chrysanthemum with mango, pineapple, pomelo and lemon; it has the gentlest fizz, 33 kcal. Strawberry uses dried strawberries, apple and roselle; it is the sweetest and fizziest, 66 kcal.
Unopened at 1–7°C it keeps 35 days; the date is printed on the can. It keeps fermenting slowly in the fridge, so it gets more tart and fizzy toward the date. Once open, finish it soon.
The bubbles come from the live cultures, and there are more in hot weather, right after delivery or near the date. Chill it well first, pull the tab slowly and pause at the hiss to let the bubbles settle.
Yes. It is fermented naturally with live cultures, so floating bits or sediment are normal.
Yes. Fermentation needs organic cane sugar as food for the grains, and they eat part of it. Sugar per can: osmanthus 8.3 g, blueberry 9.4 g, strawberry 16.5 g; 33–66 kcal. Each flavor’s nutrition label is one tap away above. If you follow a special diet, ask your doctor first.
Yes. It is fermented in water with no milk or lactose, and the can is marked vegan. The facility’s equipment also handles milk, so take care if you have a severe milk allergy.
It is caffeine-free: fine for adults and older people, and for children over one with no special dietary restrictions. If you are pregnant or follow a special diet, ask your doctor first.
