Starter culture

Nuruk 누룩

nuruk (Korean makgeolli starter culture: 누룩)

You’ll need this starter culture to make makgeolli (Korean rice liquor:막걸리). It’s made from a dough made of coarsely-ground grain and water naturally inoculated with bacteria, fungi, yeast, and lactic acid bacteria. It jump-starts the fermentation process and helps you make a delicious fermented beverage.

It’s available in Korean grocery stores, usually on the shelf next to malt powder or mung bean starch in the grain section.

    Could you use the leftovers once you make makeogeolli I have made makeogelli twice and this time I kept the “rice remains” with the nurak in it I bought online. I kept it In my fridge for several days but it is crumbly like nurak . If I dried in my machine it It seems very similar in look to the original Nurak, if I did it below 110 the yeast would not die??
    I wonder if it would have enough wheat elements to work?

    Hi maangchi, I have these two packages: the first is 15g powdered rice Koji starter (enough to make 2 babatches of 2.5 lbs. koji each. Aspergillus oryzae and rice flour).
    The second is a pack of one pound of AMYLASE ENZYMES FORMULA (0.1-0.3 teaspoons per gallon to convert starches into fermentable sugars).
    I can use the second as a starter?

    I found an unopened bag of nuruk in my pantry. It expired 2012. Can I still use it?

    Do you know if there are any stores who will ship to Canada. I’ve been looking everywhere for this stuff and it doesn’t look like you can buy it online here. I tried Hmart and they only ship within the US and the canadian site doesn’t let you buy anything. The only place I can find it is on Ebay and they want way too much.

      hello everybody am 56yo korean american recalling from childhood memory my mother used to make nuruk and rice wine, she used wheat after soakjng into the water almost one day and drain it hit with stick and steam, wrap with cloth keep it in warm place one day, and dry it under shade area it become nuruk. i want to give you the main essential things about nuruk it is white bacterial fungus. the rice, wheat, and barley can acquire white bacterial fungus. these white bacterial fungus is main agent to make sugar and alcohol, i have been researching how to make nuruk or similar things nobody say about how to make nuruk accurately, probably if i used korean language i might find more accurate information. nuruk is no longer mysterious secret recipe, you can make nuruk as long as nuruk acquires white grayish or blackish fungus thats the main point. if you have any korean friend request them to research more in korean. whether you steam or roast or make dough it will serve the function of nuruk. the ifugao in the philippines (cordillera mountain ethnic people) also make bubot, after roasting glutinous rice they mix the powder of certain root crop from the mountain make round cake while drying up it acquires blackish fungus, the ifugao rice wine also have unique taste they roast before mixing with the bubot they roast rice almost burning level. amount of wine is too little compare to japanese sake or korean rice wine but after draining the original wine they add much sugar and water let it fermented. i hope it can be helpful for everybody. Thank you.

    Homebrew stores like Northern Brewer (http://www.northernbrewer.com/) should sell things like Koji Spores (Aspergillus oryzae), Lactobacillus Bacteria, and Beer Yeast (saccharomyces cerevisiae), in addition to citric acid powder, and other ingredients you may with to use.

    Here is a PubMed article analyzing the contents of Korean Nuruk: http://www.ncbi.nlm.nih.gov/pubmed/23314366.

    Hello Maangchi!

    I’m just curious about the amazon link– As far as I can tell it’s JUST the enzyme amylase, which means it doesn’t contain any of the fungi, lactobacilli, or other bacterias. So all it would do is convert the starches in the rice to readily available sugars, which the yeast would then convert to alcohol and carbon dioxide. Is there another way to introduce the right fungi and bacteria to make makgeolli if we can’t find Nuruk?

    Thank you!

      Hi Kitukwfry,

      Nuruk is nothing more than sourdough bread starter that has been dehydrated. Literally! It contains the bacteria and yeast that is naturally on the wheat. It is made by wetting ground whole-wheat with water, then letting it ferment, nothing else. Then the wheat is dried, packaged. Nothing else is added to nuruk. I posted a link on how to make it (time and temps). It is in this thread:

      https://www.maangchi.com/talk/topic/rice-wine-and-barley-malt-flour

      Or just buy nuruk on-line. I posted a link to it in the comments section here:
