Second fermentation is an additional fermentation step to add excitement to your brew. Sugars are converted to acids, trace levels of alcohol and carbon dioxide gas which generates a huge amount of pressure, that's enough to cause cheap, low quality bottles to explode. This is why we launched these high quality bottles.

You can experiment with a range of different juices, whole fruit pieces, honey, herbs, spices and superfoods to create an endless range of different flavour and nutritional combinations. The fermentation helps to unlock nutritional compounds in your foods, making them more bioavailable but most appealing is it creates the most delicious probiotic fizzy drinks and milk kefir, low in sugar and much more economical and probiotic rich than store bought products.

How to Second Ferment Kombucha or Water Kefir?

1) Once you've fermented your milk kefir, kombucha or water kefir, mix in a jug, 1 part fruit juice with 9 parts Kombucha/ Water Kefir + any spices and superfood like turmeric, acai, spirulina, maca, matcha etc + any herbs like mint, basil etc

There are lots of recipes ideas in our free NourishmeOrganics VIP Group here

2) Pour Mixture into Second Ferment Bottle, leaving 3 to 5 cm headspace and cap tightly.

3) Leave at room temperature for 2 to 7 days depending on the weather at the time i.e a warmer temperature will result in a faster second ferment ( the longer you leave the less sugar will be left but your brew will be more sour and potentially higher in alcohol**). We recommend tasting your brew daily to establish the taste that you like, and at this point you can end the ferment. Tasting is a good way to remind you to open and release any excess pressure in the bottle.

4) Transfer brew to a refrigerator to chill.

5) Open and Serve*

How to Second Ferment Milk Kefir?

1) Once you've fermented your milk kefir, mix in a jug, milk kefir + honey + fruit pieces + any spices and superfood like turmeric, acai, spirulina, maca, matcha, chia seeds etc + any herbs like mint, basil, nuts etc. We recommend starting with a small piece of lemon or orange peel or a couple of fresh berries. You can even make a savoury version using garlic, pepper and herbs. The flavour combinations are endless. So have a play.

2) Pour Mixture into Second Ferment Bottle and cap tightly.

3) Leave at room temperature for 1 to 4 hours.

4) Transfer brew to a refrigerator to chill.

5) Open and Serve*

*Caution: Water kefir and Kombucha Second Ferments may become very fizzy so be careful when opening lid after fermentation

Raw Organic Vegan Water Kefir Grains 15g + Recipe E-Book

Best Investment

I purchased the Reuter-i Pro with 2 jugs. Used Nourishme Reuteri Culture Starter and NMO Chicory Root. My first batch separated as expected however the taste was delicious. I stirred in the whey so can drink it. Prepared my second batch this morning - took me a whole 2min!! Sterilized both jugs at same time so was ready to use. I have a 4 jar reuteri maker and it was a hassle cleaning and sterilizing4 jars and only made 1.5lt. This makes 2lt and machine being preset I don't have to press buttons 30 times to set temperature and time. Also have used capsule culture starter in the past, however I found the NMO starter to be the best. I am sensitive to EMFs and some frequencies are being trialed in my area (6g or something else? don't know) and 2 months ago I developed what looks like a radiation burn on my face and neck, very red and itchy, especially when the frequencies are turned on/up? I have consumed over a cup of reuteri yoghurt daily for 2 days and put some on my face yesterday, already have diminished itching and reduction in redness. Skin still very flaky with raised areas but this is the first thing that has made a difference, and I have spend $ hundreds on creams and omitted any foods that I thought may be a strain on immune to help deal with the affected skin. Now I'm on the right track, at last. My next batch will be the NMO Coagulans. Thank you for the excellent communication and support Nourishmeorganics have given me, I am so grateful.

Reuter-i Pro Yoghurt & Fermentation Maker — 5-in-1 Precision Fermenter with 2L Borosilicate Glass Jar

L.reuteri

Hi. We have used this brand before and were very happy with it. The last brand we tried was oxiceutics which has 20 billion bacteria capsules but this LR08 has 100 billion. So I'll be comparing the effects. I'd forgotten that the first batch separates but it's all good. I also alternate with L. Gasseri. which seems to have a positive effect on my digestion. Very happy with them both ☺️ 👍

Lactobacillus reuteri LR08 Starter Culture — 3 x 1g Sachets (100 Billion CFU/g)

Reuteri Yoghurt maker

I found this yoghurt maker very easy to use. The yoghurt separated a bit but I believe that can happen when using Reuteri capsules for the first time.
The unit is quite bulky to store.
