What accessories do I need to make water kefir myself?

Fermentation vessel – Which material is suitable?
As with Kombucha, glass is best, in addition to the advantages that it is scratch-resistant and dishwasher safe, does not adversely affect the ph value in the fermentation vessel and unlike plastic no particles evolves in the content of the glass.

If the ceramic vessel contains no coating of metals or paints, food-grade ceramic is usable.

Again, as with ceramics, porcelain must be uncoated.

Fermentation vessel – Which material is NOT suitable?
Unfortunately, plastic is on the contra side, as long as it’s not a really high-quality plastic material, as scratches can easily form in plastic and release substances that can easily spread in your water kefir. This can not only flavourful , but especially health, lead to problems. Therefore, we advise against plastic.

Crystal vessels such as vases usually have a coating and are therefore also extremely unsuitable.

Unfortunately, metal is also not one of the suitable fermentation vessels, as this not only inhibits the growth of Wasserkefirs, but can even stop completely.

How big does the water kefir jar have to be?
The size of your fermentation vessel should depend primarily on your production volume. Ideally, you’ll need to recycle the batch more often to provide enough of the nutrients to the cultures. This means using a smaller fermenting vessel.

Cover your water kefir batch
The right cover is crucial for the success, since no oxygen into it, but should come out during the fermentation process carbon dioxide addition. If a glass with a screw cap is used, it must not be tightly closed, but only lightly tightened. Ideally, use your cling film, which is attached to the top with a sturdy and solid household rubber. Thus, no oxygen and no insects such as ants or fruit flies get into the water kefir batch, but the carbon dioxide can escape. With our special fermentation pack (Airlock) water kefir production is even easier.

NOT suitable cover of your waterkefir batch
Unsuitable as a closure are air-permeable lid and woven material (in addition to oxygen could also get small insects through the holes access to your kefir).

Ideal place during the fermentation
It is best to set your water kefir batch to a warm (ideally 24 degrees), sunny spot. When the sun is shining and the ideal temperature is reached, your batch will gain momentum, allowing you to produce your kefir in minimal time.
Even without direct sun, an absolutely good success is possible at any time.

    Vielen Dank für dieses Video, zum Einstieg ist es für mich sehr wertvoll.
    Kann ich Wasserkefir auch zusammen mit Soja- oder Hafermilch zubereiten?

      Lieber Silvio,

      vielen Dank für Ihren Kommentar:-)

      Wenn Sie das Wasser einfach durch Hafer- oder Sojamilch austauschen funktioniert das. Diese Pflanzenmilchsorten bestehen ja zu 97% aus Wasser:-)

      Liebe Grüße

    Ich verstehe das nicht ganz:
    Wenn ich Frischhaltefolie mit einem Gummi über das Glas ziehe, ist das doch luftdicht abgeschlossen?
    Den Deckel hingegen soll ich nicht fest zudrehen, damit es nicht luftdicht abgeschlossen ist.
    Ist das ein Widerspruch?

      Lieber Henry,

      vielen Dank für Ihren freundlichen Kommentar!

      Der Eindruck könnte entstehen, da haben Sie recht. Wenn Sie die Frischhaltefolie mit einem Gummiring fixieren und der Druck im Glas wächst, wird dieser überschüssige Druck trotzdem entweichen können, weil der Gummiring etwas nachgibt. In der Praxis wird Ihnen das dann auch sicherlich auffallen.

      Viel Spaß beim Fermentieren.

      Liebe Grüße
