Miso is a traditional Japanese seasoning made from fermented soybeans. It’s a staple ingredient in Japanese cuisine that has been produced for centuries. However, there has been some debate among Muslim consumers over whether miso is considered halal. This article will examine:

  • The background on miso and how it’s produced
  • The alcohol content in miso from the natural fermentation process
  • Efforts by some companies to certify miso as halal
  • Islamic opinions and fatwas on the permissibility of consuming miso

What is Miso?

  • First Miso is made by fermenting soybeans with salt and koji mold. This process takes months and results in a thick, rich paste.
  • There are many types of miso with varying flavors, colors, and ingredients:
    • Red miso – Made with soybeans fermented for longer and often contains rice or barley. Stronger flavor.
    • White miso – One of the main ingredients is soybeans fermented for a shorter time. Milder and sweeter.
    • Mixes with additions like mushrooms, grains, including vegetables.

“Typically Miso is one made by combining dark soybeans and grain with salt and koji, and allowing the mixture to ferment. The final product is a thick paste used for sauces and spreads.”– Harvard Health

Some well- know miso brands like Marukome and Miso Master are now exploring halal certification.


Alcohol Content in Miso

Miso inaka contains trace amounts of alcohol due to the natural fermentation process. Here are some key points:

  • The alcohol content in miso usually ranges from 1-2% according to halal certification organizations:

  • Alcohol is not added during the production process but results from fermenting the soybeans and grains.

“A small amount of alcohol is produced naturally as part of the fermentation process used to make miso.” – Japan Foundation

  • The alcohol content can vary based on:

    • Miso variety (red vs white)
    • Length of fermentation
    • Type of koji mold used
Miso Variety Fermentation Time Alcohol Content
Red Miso Up to 18 months 1-2%
White Miso Up to 3 months 0.1-0.8%

Companies like Miyasaka Brewing Co. outline their miso production process and alcohol content list.


Efforts to Make Halal Miso

Some miso companies in Japan have adapted their production methods to obtain halal certification:

  • They do not add any alcohol at any stage of the process.

  • Use specific koji molds that lower residual alcohol content.

  • Monitor fermentation to keep alcohol under 0.5%.

For example:

  • Marukome obtained halal certification in Malaysia for some of its organic miso products.

  • Hikari Miso has halal certified miso made with Ophiocordyceps sinensis koji mold to minimize alcohol.

“Our halal-certified miso products are made with a unique taste koji that reduces alcohol production during fermentation.” – Hikari Miso

Islamic Opinions on Miso

There are differing views among Islamic scholars over whether miso is considered halal:

  • Many state miso is halal given the low alcohol content and lack of added alcohol in production.

    • Permitted according to JAKIM and MUIS guidelines of less than 2% alcohol.

    • Alcohol is not from an intoxicating source.

  • Some argue miso is Mashbooh (questionable) due to the intentional fermentation.

    • Fermentation is done deliberately to produce the miso, unlike bread.

“Miso is halal and permissible to consume as it contains a negligible amount of alcohol produced naturally through fermentation.” – Mufti Faraz Adam, SeekersGuidance

“I have avoided miso due to the alcohol and fermentation. There are difference of opinions on this.” –Shaykh Musa Furber

In summary, there are reasonable arguments on both sides. Some key principles to consider:

  • Alcohol source and amount
  • Intent behind fermentation process
  • Availability of halal-certified options
