Easy to prepare, makes great kefir at home!



Nourish Kefir Starter Cultures are quick and easy to use.  They are the No-Fuss way to make your own delicious fresh kefir at home (or even on the move) using your choice of fresh milk, including cow’s milk, lacto-free milk, goat’s milk, soya milk and coconut water – or even fruit juice!

These starter cultures are a reliable and make great tasting and effective kefir without the effort of having to look after live kefir grains.  Why? Because each sachet has a measured amount of kefir live bacteria and will produce 1 litre of kefir – within about 24 hours.*

You can make up to 4 subsequent ferments from your first litre that are still strong and provide billions of gut-friendly bacteria. Further batches will become weaker with each fermentation.

Nourish Kefir Starter Cultures are very useful to take when travelling abroad to keep your tummy happy!  You do not need any special equipment to prepare them- just a jug, spoon and some clingfilm to cover.

The standard pack contains 6 x 5g sachets for £16.79

Each sachet makes one litre of kefir with your choice of milk.

Please note – our kefir starter cultures are made from grains but will not turn into grains!
At Nourish Kefir we love our kefir grains and totally understand  why other people want live grains!  However, live kefir grains are like a pet – you need to look after them.  (Also they can be a bit temperamental and sometimes your kefir will taste too strong or your grains will die if they are neglected!).  At our dairy we look after them every day!

Convenience without compromise
We understand that time pressures mean, you need convenience without compromising quality – and that’s exactly what our Starter Cultures provide.  They are a reliable way to make sure you and your family have lots of kefir, with your choice of milk – as often as you want it!   Use them when you want to make some kefir, keep them in the fridge when you don’t!

Please note that some brand of ‘alternative milks’, will not ferment well because they are predominantly water based and the water will not ferment. We’ve tried most and these include Almond milk, rice milk, hazelnut milk.  As for Coconut milk – there are quite a few varieties and some will actually work ok – though most will not ferment well – our favourite brand is Grace.
*Fermentation times vary – in hot weather fermentation is faster, typically 18 hours!

    I’ve just made up my first batch of kefir from one of the starter cultures. It was really easy to mix and developed well in 24 hours, even though my kitchen is not that warm. I mixed one litre of kefir (made with skimmed milk) with two mashed bananas and a tablespoon of honey, and poured myself a glass. Fantastic! Silky texture and fabulous flavour, it took all my willpower not to drink the whole litre. But I want to save some so that I can have a glass every day, and see what it does for my intestines (depleted of bacteria by chemotherapy). Looking forward to the next glass already!

    I have been using these starter grains for over a year now and they are really easy to use. I use lactose free milk (fresh) and use a metal hand whisk to mix the sachet in a small amount of milk in a large glass jar, to make sure that the culture is all blended. Then slowly add in the rest of the milk, whisking all the time. I then put on the lid, and leave it on the kitchen counter until the next day, by which time it has set to the consistency of set natural yogurt.

    I then keep the jar in the fridge and use it like yogurt over a few days until I am down to one cupful, which I then use to start another batch. I just whisk in another litre of fresh milk into the jar and leave it out of the fridge overnight. (After the second batch I decant to a clean jar). Usually by the 4th batch it is starting to get ‘fizzy’, which is when I start afresh with another sachet.

    The most number of batches I have gotten out of one sachet is five, but that 5th batch was a bit sour, as the original milk would have been getting old by then – so I left it for several days longer until it separated into curds and whey and made a soft cheese with the curds and used the whey for starting some saurkraut.

    I have tried using goats milk but it didn’t set very successfully. I’m just about to try it with coconut water – the reason I came on this site to have a look at see if it was possible. Now that I see it is, I’m going to give it a try.

    I have found my digestion has vastly improved since I started using this culture and also eating fermented vegetables like saurkraut.

    I would highly recommend this product. I thought it a bit expensive at first, but at 3 or 4 litres per sachet, it is good value for money. That’s about 20 litres, so under a £1 per litre even with the cost of the milk.

    Fantastic! I am so happy with this product! I can whip up a litre of kefir whenever I want it, without going miles and miles to buy some already made, and spend a lot of money on it. The sachets arrived quickly and the instructions are very helpful. Ordering again!

    I’ve grown to love my home-made Nourish Kerfir. Normally I have problems tolerating dairy but have been mixing these sachets with full-fat organic milk and had no issues (I tried mixes with coconut milk, coconut water and semi-skimmed milk but did not get as good results). I’ve found that the Kerfir seems to really help my digestion and alleviate acid reflux that has upset my sleep for years. The sachets are simple to use and I have got a number of batches from each one, so for me they have worked out very economical in the end. I would definitely recommend giving them a go.

    Great product, reasonably priced, prompt delivery. I use a mixer (glass bowl, plastic blade) on a low setting to combine milk and kefir grains: works well and saves time.

    Having had the convenience of ready made kefir, I was unsure whether it was worth making my own. I placed my order with Nourish and was not only extremely pleased with the prompt delivery, but soon realised that with very little effort I have a superior product.

    The sachets of Kefir culture are absolutely great – convenient and really quick to form into a batch of healthy kefir. I’ve used the sachets successfully with unpasteurised organic milk, pasteurised organic milk and soya milk. They’re all different but all delicious. I must admit to ignoring the instructions about initial stirring and then not stirring as I use a large Kilner jar into which milk and culture goes, then I shake hard to combine and shake repeatedly during the 6-12 hours to culture.
