What is Natto?

Nattō (なっとう or 納豆?) is a traditional Japanese food made from soybeans fermented with Bacillus subtilis var. natto.  Some eat it as a breakfast food.  Nattō may be an acquired taste because of its powerful smell, strong flavor, and slimy texture.  In Japan, nattō is most popular in the eastern regions, including Kantō, Tōhoku, and Hokkaido.

Before Making NATTO:

  • Be sure the entire processing area is cleaned for production.  Make sure all utensils, pots, cheesecloth (FUKIN), etc. are as sterile as possible.  (Boil utensils for 5 minutes prior to using.)
  • The packet of NATTO spores comes with a special small spoon; be sure to use the small spoon to measure the appropriate quantity for the recipe.
  • The fermentation process requires the NATTO be kept at approximately 100°F (37°C) degrees for 24 hours.  Ovens with a low temperature setting can be used, an oven w/ light on only, or inoculate in large cube-shaped food dehydrators.
  • NATTO is quite odorous while fermenting, and you may want to isolate the fermenting NATTO during this time.

Ingredients and Supplies
needed for Making NATTO:

  • 2 pounds (900g) soybeans (about 4 cups)
  • 10cc water, boiled for 5 to 10 minutes to sterilize
  • One spoonful (0.1 g.) NATTO-kin spores (use the special spoon that came with the packet)
  • Cheesecloth or butter muslin (FUKIN in Japanese)
  • Non-reactive pot (i.e., stainless steel, enameled, ceramics, etc.) or Pressure cooker
  • Large stainless steel, wood, or plastic spoon or spatula
  • 3-4 oven-proof glass containers with lids

Instructions for Making NATTO:

– Wash the soybeans using running water to gets rid of tiny dirt or dead skins off the beans.
Cooking the soy beans for natto– Soak with clean water for 9 to 12 hours (longer soaking time recommended during colder months). Be sure to use approximately 3 parts water and 1 part soybeans to allow for expansion. You will end up with 8 to 12 cups of beans.

soaking the soy beans over night

– Drain the beans from the soaking water. Place beans in a large pot with mesh bowl and pour in water. Steam it for 3-4 hours.
Or fill with water and boil 5-6 hours. 
The recommended way is to use a “Pressure cooker”, that can be cooked faster than in a normal pot. Please refer to the
pressure cooker instruction manual for operation guidelines.

steaming the soy beans for fermentation

– Drain the cooked beans and place in a sterilized pot. Dissolve 1/5 special spoonful of NATTO spores (0.1g) into 10cc of sterilized water.

preparing the natto spores

– Immediately pour the NATTO spore solution over the beans while the beans are still warm but not hot to the touch. Stir the beans and water mixture together carefully using a sterilized spoon/spatula.

mixing in the spore mixture

– Place a thin layer of beans in each of the 3 to 4 containers. If at any point during the process some beans are spilled on the counter, etc., discard the spilled beans as they can contaminate the other beans if added back in to the batch.

mixing the beans and spores

Place the sterilized cheese cloth over the top of the containers and place the tight-fitting lid over the cheese cloth. Preheat the oven, dehydrator, or KOTATSU Japanese Warmer to 100°F (37°C).  Place the covered containers in the oven, dehydrator, or warmer and allow the NATTO to ferment for 24 hours being sure to keep the temperature steady at 100°F (37°C).  Check the temperature throughout the day/night.

fermenting the soy bean mixtureAt the conclusion of the fermentation period, let the NATTO cool for a couple of hours, then remove the lid and the cloth, replace the lid, and store the containers in the
refrigerator at least overnight.

NATTO can also be aged
in the refrigerator for 3-4 days. Smaller portions of finished NATTO can be stored in the freezer and thawed for later use.

A Summer Time Refresher – Ginger Brew & Beer

Old time ginger brew beer…refreshing!

A Summer Time Refresher –
Ginger Brew & Beer

It’s the middle of the summer season and the desire for a cool refreshing beverage to quench the thirst is a plus. Coming in from an afternoon of tending to the organic garden, I pop the top on a 12oz ginger brew and pour into a Champaign glass. I watch for a second as the bubbles turn into a lovely foaming head and the smells of ginger, lemons, and limes transcend the air. The sweet flavors collect on the tongue and fulfill my thirst.

Making your own soda beverages is fun, easy, and a much better alternative to commercial sodas loaded with HFCS and dyes! Before the coming of mass produce cola and the ‘soda jerk’, many people made their own beverages with natural effervescence. The process is simple and the final recipe take less than an hour to complete. You can make two different types of ginger beverage – A classic ginger ale (what we call ginger brew) or an alcohol version, which is ginger beer. Both follow a simple recipe, however, the processing is different for each type. The first thing you will need is a ginger beer plant or ginger brew/beer culture starter.

What’s a Ginger Culture Starter and Ginger Beer Plant?

To make ginger brew/beer you will need to obtain a starter or plant. There are three choices to get started:

  • First, a traditional ginger beer plant that comes from the UK and can cost a bit. This culture seems harder to find and maintain. We find that the taste is strong and sharp, not to our liking.
  • Second, buy a ginger brew starter. There are a few sources for this style of starter.  We sell a lot of this starter in our store. You can buy ginger beer starter here: http://store.organic-cultures.com/gibeplorgr.html. This ginger beer starter has been maintained since 2009 and has improved in flavor over time. We have stabilized this culture starter to produce the same results and taste again and again. It is a cross between the UK ginger beer plant and wild yeast strains. We think this starter is mellow while still holding an intense ginger flavor over the UK strain alone!
  • Lastly, you can try to make a ginger brew/beer starter with wild yeast and sugar. Making your own starter using wild yeast strains may produce good results or sometimes not. This depends on the yeast strains you capture and if they can stabilize. Just as in beer brewing, a stabilized yeast starter will produce a fermented beverage with the same results again and again. Some try to do a quick start using bread or Champaign yeast, we do NOT recommend using these as the taste will lose its balance and the traditional ginger ale flavor.
  • Fakes – There are sellers who claim to have a ‘real’ ginger beer plant. These are not true plants most being water kefir grains or bread yeast mixed with ginger.

Which to Do…Ginger Brew/Ale or Ginger Beer?

For a great ginger flavored beverage, there are two ways to go alcoholic (ginger beer) or non-alcoholic (ginger ale/brew). Again, the main recipe is the same only the process changes. For making ginger brew/ale you can just follow the standard recipe on our website: https://organic-cultures.com/instructions_sheets/ginger_brew

For ginger beer, make the final recipe for ginger brew/ale but instead of bottling it in beverage bottle it is placed into a fermentation vessel with an airlock (We have gallon size jars with lids and airlock at the store). Once the airlock stops releasing rapid bubbles, the beer is finished and now decanted into beverage style bottles. The volume of sugar used in the recipe determines the amount of alcohol.

Whether one wishes to make beer or brew ale, a ginger culture starter can provide a great refreshing summer time beverage. Not only will it save money over the cost of commercial soda, it is much healthier. Other benefits include the ability to flavor the drink as one wish. Ginger with limes, maybe fresh berries, or even ginger/lemongrass make it how you like!

So this summer, start making a pro-biotic thirst quenching ginger beverage to refresh during the heat. Ginger is known to aid in digestion and helps provide energy. Ginger brew is easy to make and a great replacement for the whole family vs. commercial soda. Buy or get a ginger brew starter today and
start making this wonderful summer time beverage.
