- 20 g of live milk kefir grains.
- A live kombucha SCOBY with starter liquid.

How to start a batch
Three jars, three rhythms: water kefir and milk kefir are ready after 24 hours, kombucha after 7 to 10 days. The guides to water kefir, milk kefir and kombucha explain every step.
Storing the cultures
Water kefir: between batches, the grains wait in the fridge in fresh sugar water for up to two weeks.
Milk kefir: need a break? Put the grains in fresh milk in the fridge, where they'll wait for up to a week.
Kombucha: between batches, the SCOBY stays in a little finished kombucha, covered, at room temperature.
Can't start on the day they arrive? The cultures wait in their pouches in the fridge for two to three days.

Three living drinks from your own kitchen
Water kefir as lemonade, milk kefir at breakfast and kombucha for the weekend. The complete kit is the best-value way to try the lot.
Water kefir
Fresh and fruity, 1 litre every 24 hours.
Milk kefir
Creamy and tangy, fresh every morning, and a ready-made stand-in for buttermilk.
Kombucha
Aromatic, made with your tea, in 7 to 10 days.
The biggest saving
You save £7 compared with buying the three cultures separately, and the kit alone passes £35, so standard delivery is included.
How it fits into your week
| Culture | Work | Ready after | Lovely with |
|---|---|---|---|
| Water kefir 30 g | 2 minutes a day | 24 hours | Lunch, barbecues, instead of fizzy drinks |
| Milk kefir 20 g | 2 minutes a day | 24 hours | Porridge, smoothies, scones, pancakes |
| Kombucha SCOBY | About 10 minutes a week | 7 to 10 days | Weekends, Sunday dinner, salad dressings |
Start all three on the day they arrive. If that's not possible, they wait in their pouches in the fridge for two to three days. There's a guide ready for each one, and plenty of ideas in the recipes.
Where to begin with each jar
Water kefir. Sugar water, a dried fig, a slice of lemon, the grains, a cloth on top. The guide to your first days with water kefir walks you through the first week, and strawberry water kefir is the classic first flavour.
Milk kefir. Grains into a litre of whole milk, 24 hours, strain, repeat. Everything is in how to make milk kefir. Once you have a jar to spare, try it in place of buttermilk in your next batch of scones.
Kombucha. Sweet tea, the starter liquid and the SCOBY, then a week of patience. Follow how to make kombucha, and when the first batch is done, a berry kombucha with hedgerow blackberries is hard to beat.

Great client service I ordered kombucha SCOBY and water kefir grains and when the package arrived, a part of the kefir was missing. Client service was very quick at sending me the missing item. Both grains and SCOBY are producing great drinks.
Juliette MaysReview on TrustpilotExcellent service and fantastic culture kits!Highly recommended! I recently purchased the culture kits for both water kefir and kombucha, and I couldn’t be happier! The package arrived right on time and was packed with so much care. To be honest, I was a bit nervous at first, but the instructions are incredibly clear, thorough, and easy to follow (the included booklet is an amazing guide if you're a beginner like me!). Both cultures worked perfectly on the very first try, and the drinks taste absolutely delicious.
