How long should I ferment my water kefir?WATER KEFIR+
Usually 24 to 48h at 20-25°C. The most reliable sign: the fig rises to the surface. The drink becomes slightly cloudy, fizzy, and most of the sugar is gone.
My water kefir is too sweet, what should I do?WATER KEFIR+
You strained too early. Let it ferment 12 to 24h longer, until the fig clearly floats up.
My water kefir is not fizzyWATER KEFIR+
The fizz comes from the second fermentation in a sealed bottle. Strain, bottle with a little fruit, seal tightly and leave 24-48h at room temperature.
Can I replace the sugar with honey?WATER KEFIR+
No. The grains need sucrose. Honey has antibacterial properties that harm the grains. Raw cane, whole cane or white sugar all work.
Which milk should I use for milk kefir?MILK KEFIR+
Preferably organic whole milk, pasteurised or raw. Absolutely no UHT or skimmed milk. Plant milk is not suitable.
Is milk kefir suitable if I am sensitive to lactose?MILK KEFIR+
Fermentation reduces the lactose content by 70 to 80%. Many people with mild sensitivity find it comfortable. If you are severely intolerant, water kefir is the better choice.
Can milk kefir be turned into fresh cheese?MILK KEFIR+
Yes! Let it ferment 48h, then pour it into a fine cloth and hang it. Drain 12-24h in the fridge for a creamy labneh.
My milk kefir grains float, is that normal?MILK KEFIR+
Yes, completely normal. The CO2 produced by the grains makes them rise.
How long should I ferment my kombucha?KOMBUCHA+
7 to 14 days depending on the temperature and your taste. Shorter = sweeter. Longer = more tart. Taste from day 7.
How do I rescue a culture that got mouldy?KOMBUCHA+
Keep the original disc, run a new fermentation for 5 days, then start again with the disc + 100 ml of the liquid for 8 days. If it does not work, a new culture will be sent to you.
My SCOBY sank to the bottom, is that a problem?KOMBUCHA+
No. The SCOBY can float, sink or hover in between. What matters is that a new disc forms on the surface.
My kombucha tastes like vinegar, what can I do?KOMBUCHA+
Fermentation went too long. Reduce by 2-3 days, or dilute with fruit juice. You can also use it as homemade vinegar!
Does kombucha contain alcohol?KOMBUCHA+
Very little: 0.5 to 1% max, below the threshold of a non-alcoholic drink.
How much liquid rennet for 1 litre of milk?RENNET+
2 to 4 drops of our high-concentration rennet (110,000 U) for 1 L. Dilute in a little cold, non-chlorinated water.
My curd is not forming, why?RENNET+
Frequent causes: UHT milk (does not curdle), wrong temperature (must be 30-35°C), chlorinated water used to dilute, or expired rennet.
I can see mould (green, black, fuzzy)PROBLEM+
Kefir: throw everything away, a new culture will be sent (lifetime guarantee). Kombucha: first try the 5-day + 8-day rescue method.
I am going on holiday, how do I store my grains?PROBLEM+
1 week: jar with water + sugar in the fridge. 2-4 weeks: change the bath every 15 days. Longer: freeze the rinsed and dried grains (6 months max).
My grains are shrinking or disappearingPROBLEM+
Check: chlorinated water (switch to filtered water), refined white sugar (try raw cane sugar), reactive metal (switch to plastic), UHT milk (switch to whole non-UHT milk).
What are the delivery times?ORDERS+
France: 3-5 days (standard), 24-48h (express). Belgium/Switzerland: 4-7 days. Italy/Spain: 5-8 days. Rest of Europe: 7-12 days.

Can I use tap water for water kefir?WATER KEFIR+
Yes, but chlorinated water slows fermentation. Let the water sit 2h in an open jug so the chlorine evaporates, or use filtered/spring water.
How long does water kefir keep once strained?WATER KEFIR+
In the refrigerator, 5 to 7 days in a closed bottle. The taste evolves: it gets more tart over time. Ideally, drink it within 3 days.
My grains changed colour, is that normal?WATER KEFIR+
Yes. Grains take on the colour of the ingredients: brownish with raw cane sugar, pinkish with red fruits. Only mould (green, black, fuzzy) is a problem.
Can I make milk kefir with goat or sheep milk?MILK KEFIR+
Yes, and it is excellent! Goat milk gives a lighter kefir. Sheep milk gives a creamier, richer kefir. Always whole milk, never UHT.
How do I know my milk kefir is ready?MILK KEFIR+
The milk has thickened (drinking-yogurt texture), with a light sweet-and-sour smell, and sometimes visible whey separation on the sides of the jar. Taste it: it should be creamy and tangy.
Can I make kombucha with loose leaf tea?KOMBUCHA+
Yes, it is even recommended! Use 8 g of loose leaf tea (black, green or a blend) for 1 litre. Make sure you strain the leaves out well before adding the SCOBY.
My kombucha smells like vinegar, is it still good?KOMBUCHA+
Yes, it is safe but very fermented. Use it as kombucha vinegar (dressings, marinades) or as starter liquid for your next batch.
Is the rennet vegetarian?RENNET+
Our rennet is animal-based (extracted from calf abomasum), the traditional and most effective form. For a vegetarian alternative, some shops sell microbial rennet.
Can I use the rennet with pasteurised supermarket milk?RENNET+
Yes, pasteurised milk works very well. Only UHT milk (sterilised at high temperature) is unsuitable, because its proteins are too denatured to coagulate properly.
My parcel arrived warm / late, are the cultures still good?PROBLEM+
The cultures are resilient and survive shipping very well (up to 5-7 days). Activate them as soon as they arrive. If nothing happens after 5 activation cycles, contact us for a free replacement.
