Kefir is milk fermented with kefir grains, a culture of bacteria and yeasts; the yeasts produce carbon dioxide and a little ethanol.

Next step Kefir is fermented milk, and its yeasts make a little alcohol. IslamQA and Indonesia's MUI treat non-intoxicating kefir as Halal; IslamWeb forbids it if any alcohol is proven. Follow the view your scholar holds. How to verify

Scholarly differences

The difference is about non-intoxicating alcohol formed by fermentation. IslamQA divides fermented drinks into those that intoxicate in large amounts, which are khamr and forbidden in any amount, and those whose alcohol is so small that no quantity intoxicates, which are Halal; it puts kefir in the second group.

IslamWeb applies the hadith 'Whatever causes intoxication when taken in a large quantity is also forbidden to take in small quantities' to any proven alcohol in kefir. LPPOM MUI, citing MUI fatwa 10/2018, treats fermented foods containing alcohol as Halal if the process uses nothing forbidden and they are harmless.

What decides the answer

  • Kefir that does not intoxicate in any amount

    Halal per IslamQA and MUI

  • Kefir with any proven alcohol

    not permitted per IslamWeb

  • Kefir drinks with added alcohol

    not Halal

How to verify

  1. UK kefir drinks such as Biotiful and Yeo Valley list only milk fermented with live kefir cultures.
  2. Neither lists an alcohol content; fermentation alcohol isn't declared on the label.
  3. Decide by your scholar's view on non-intoxicating fermentation alcohol.
  4. Water kefir and flavoured kefirs are separate products; read their lists.

Quick checks

  • Milk fermented with kefir grains.
  • Yeasts make a little alcohol.
  • IslamQA and MUI permit; IslamWeb does not.

Why this ruling

Kefir is a fermented milk drink from the Caucasus, now sold in UK supermarkets. Its culture includes yeasts as well as bacteria, and that's where the Halal question comes from.

What's in it

UK kefir drinks list very little: Biotiful's is pasteurised cow's milk fermented with live kefir cultures,[4] and Yeo Valley's is organic milk fermented the same way.[5] The yeasts in kefir grains produce carbon dioxide and a small amount of ethanol. IslamQA's answer puts it at about 0.1 to 0.5% in normal fermentation, rising to as much as 3% depending on preparation.[1] Labels don't state it.

Permitted: IslamQA and MUI

IslamQA divides fermented drinks into two kinds: those that intoxicate if drunk in quantity, which are khamr, and those whose alcohol is so slight that no amount intoxicates, which are Halal. It places kefir in the second group.[1] An LPPOM MUI article, applying Indonesia's 2018 fatwa, says fermented foods containing alcohol are Halal if nothing forbidden is used and they are harmless.[3]

Not permitted: IslamWeb

IslamWeb answers that if kefir is proven to contain alcohol, "it is not permissible to get benefit from it, even if the percentage of alcohol is little", citing the hadith that whatever intoxicates in large amounts is forbidden in small amounts.[2] The same split appears for kombucha and non-alcoholic beer. Ordinary yogurt, made with bacteria alone, doesn't raise it.

Where you'll find it

  • Fermented milk drink
  • Kefir yogurt
  • Smoothies and overnight oats

Frequently asked questions

Is kefir Halal?
Scholars differ. IslamQA rules it permissible because the alcohol from fermentation is too little to intoxicate, and Indonesia's MUI treats such fermented foods as Halal. IslamWeb says that if kefir contains any alcohol, it may not be consumed.
How much alcohol is in kefir?
IslamQA's answer cites about 0.1 to 0.5% during normal fermentation, rising to as much as 3% depending on preparation and yeasts. IslamWeb's question mentions 0.8 to 2%. Supermarket kefir labels don't state it.
Is kefir yogurt Halal?
The same question applies wherever kefir cultures with yeasts are used. Some kefir yogurts, like Biotiful's, also use ordinary yogurt cultures; the label shows which.
