The complete kit: water kefir, milk kefir and kombucha in one parcel
At a glance
The complete kit gathers the three Natural Probio drink cultures: 30 g of water kefir grains, 20 g of milk kefir grains and a kombucha SCOBY in its starting liquid, each with its own guide. You can make a sparkling fruity drink and a creamy kefir that are both ready the next day, plus a tea-based kombucha ready in about a week. It is the best-value option in the range and a favourite as a present.

Some people like to dip a toe in. Others would rather open one box and have the whole picture in front of them. The complete kit is for the second group: everyone who wants to taste the full spread of homemade fermented drinks, compare them at their own pace and keep the ones that become household favourites.

A week with all three
It sounds like a lot, but the routines are short and they overlap neatly. A typical week for a kit owner looks something like this:
| Culture | How often | Your time | What you get |
|---|---|---|---|
| Water kefir | Daily | About 5 minutes | A fresh bottle every day, flavoured as you like |
| Milk kefir | Daily | A few minutes | Creamy kefir for breakfast and cooking |
| Kombucha | About weekly | A short session | A batch of sparkling tea for the week ahead |
Many customers start the water kefir on day one, the milk kefir a day or two later and the kombucha at the weekend. The guides show you how to keep the pouches you are not using yet in the fridge for a few days.
Three drinks, three moods
Water kefir is the everyday thirst-quencher: bright, fruity and fizzy, with no milk in it. Milk kefir is the breakfast and kitchen companion: thick, smooth and lightly sour, lovely with fruit or in savoury dishes. Kombucha is the grown-up sipper: tea-based, sparkling and a little sharper, with some caffeine from the tea. Between the three, there is something for every moment of the day. Our comparisons water kefir or kombucha and water kefir or milk kefir go into more detail.
Who it suits
- The curious who want to try everything rather than guess which they will like.
- Households with varied tastes, where everyone can find a favourite.
- Keen cooks and hosts who like having something homemade to pour and to cook with.
- Gift-givers looking for a present that keeps on being used. See our gift ideas.
Only fancy two of the three? The water kefir and kombucha duo and the kefir duo are lighter ways in.

Is it too much for a beginner?
Not if you take it one culture at a time. Each guide starts from scratch, and you can begin with whichever drink tempts you most.
Does it need a lot of kitchen space?
Three jars and some bottles. Most customers keep everything on one stretch of worktop and a shelf in the fridge.
Is the kit good value?
It is the best-value way to get all three cultures from the Natural Probio range. The current cost is shown on the kit's page on natural-probio.com.
Can it be sent as a gift?
