Some people know exactly which drink they want. Others would rather taste everything and decide later which one becomes a habit. The complete kit is for the second group, and for anyone looking for a generous present that keeps on giving through the week.
What does the complete kit contain?
- A live kombucha SCOBY with its starter liquidFor a jar of sparkling, tea-based kombucha, ready in a good week.
- Live water kefir grains, 30 gFor about a litre of fruity, lightly fizzy drink a day, ready the next day.

- Exclusive recipesA QR code opens our recipe library for all three drinks.
- The Natural Probio guaranteeLifetime guarantee on the activity of each culture, plus money back if you are not satisfied.
What will each culture give you?
| Culture | The drink | Ready in | When you will reach for it |
|---|---|---|---|
| Kombucha SCOBY | Sparkling tea, tangy and rounded | A good week | Aperitif, Sunday lunch, guests |
| Water kefir grains | Fruity, bright, lemonade-like | The next day | Every day, lunchboxes, sunny afternoons |
| Milk kefir grains | Creamy, gently tangy, drinkable | The next day | Breakfast, smoothies, cooking |
The three cultures are not interchangeable: a SCOBY only makes kombucha, water kefir grains only make water kefir, and milk kefir grains only work with milk. That is exactly why the kit has three guides.
How do three drinks fit into a normal day?
More easily than it sounds. In the morning, you strain the milk kefir and pour some over your granola or into a smoothie, then set the grains going in fresh milk. Later, you strain the water kefir, bottle it with whatever fruit is in the bowl and start a new jar. The kombucha needs nothing at all on most days: you start it once, then leave it to work quietly for about a week.
All told, that is around ten minutes a day, and the guides make each step obvious. If it feels like a lot at the start, begin with one culture and keep the others in the fridge for a few days, as the guides explain.

Is the kit better value than the duo?
The kit is the most advantageous formula in the range, because it brings the three cultures together in one order. The kombucha and water kefir duo is the better fit if nobody at home drinks milk, or if you simply want two sparkling drinks. The current cost of each option is shown on the official shop, and which to buy lays out the whole range side by side.
What do customers say about multiple cultures?
"Good customer service. Very happy with my milk and water kefir pack, and they're glad to advise on any question. I recommend it to everyone."

Montse AJ, October 2026Trustpilot review, translated from SpanishQuestions about the complete kit
Do I have to start all three cultures at once?
No. You can start one on arrival and keep the others in the fridge for a few days. The guides explain how.
Is it suitable for complete beginners?
Yes. Each guide starts from zero, and our team answers questions by email, usually the same day.
Are all three cultures guaranteed?
Yes. Each is guaranteed alive on arrival, and each culture's activity carries a lifetime guarantee in normal conditions of use.
Does milk kefir need special milk?
No special product is needed. The milk kefir guide tells you which milk to use and how to get the texture you like.
