Bokashi Bran Composting (how to make and use premium Bokashi bran at home)

Sharing is caring!

Bokashi bran is a clever ingredient when added to compost because it aids in accelerated fermentation with the work of essential microorganisms. Suppose you are a gardener who needs a swift, practical, and eco-friendly solution. In that case, Bokashi bran composting can be the answer to reducing food waste quickly and promoting the healthy growth of your plants.

Bokashi bran is a dried, microbe-inoculated grain bran (including lactobacillus, yeast, and phototrophic bacteria) used as a compost accelerator. It produces fermented organic waste and turns your food waste, including meat and dairy, into a valuable soil amendment. You can purchase or make your own homemade bran by mixing it along with other kitchen waste.

EM-1 In Bokashi Bran – Microbes That Accelerates Decomposition

Bokashi’s benefits specifically come from the intricate microbial work in the bokashi bran. EM-1 (effective microorganisms) adds beneficial microbes, including Lactobacillus, yeasts, and phototrophic bacteria that serve as an inoculant to infuse the bran and ferment the organic waste.

Six Easy Steps For Your Home-Made Bokashi Bran 

To make Bokashi bran at home, here are the ingredients and simple steps you can follow:


  • 2 parts wheat or rice
  • 1 part molasses
  • 1 part water
  • 1-part mix of EM


  1. Place 2 cups of wheat or rice bran in a mixing bowl. Ensure the bran is dry and free of any contaminants.
  2. Mix two tablespoons of EM-1 solution in a separate container with 1 cup of water. Stir well to ensure even distribution. 2
  3. Mix equal parts molasses and water. For example, if you add 1 cup of molasses, add 1 cup of water. Stir well to dissolve completely. Then, combine all the ingredients by hand-mixing.
  4. Transfer to an airtight container, let it sit in a warm spot, and allow it to ferment for at least two weeks.
  5. The presence of white mold when making the bran is expected, so don’t feel like you’ve done something wrong when it appears. This mold is a beneficial fungus that is part of the fermentation process initiated by the microorganisms. The microbes will inoculate it to a fermented organic matter.
  6. You can store your finished product in a cold, dark place, avoiding direct sunlight and hindering the microbes from thriving.

2 Parts Bokashi Bran And 1 Part Brown (Carbon-Rich) Medium (Sawdust, Coffee Grounds, Newspaper)

You can use Bokashi bran with any carbon-rich medium, such as newspapers, wood shavings, dregs (remnants left after brewing or winemaking), or rice hulls. Ensure that you shred them into smaller pieces and that are dry before they go into the compost bucket. Layer the waste and the Bokashi bran properly.

The ratio can vary, but a common starting point is roughly two parts bran to 1-part browns added to the compost. Add sugar, water, and microbe inoculant to create the ideal environment to ferment the scraps. 3

1 Part Bokashi And 1 Part Green Compost (Nitrogen-Rich) Materials (Grass, Vegetable And Fruit Peelings)

The ideal ratio of Bokashi added to the compost of green (nitrogen-rich) materials in a composting system can vary. Still, a common guideline is to aim for approximately a 1:1 mix.

Gather fresh green compost materials such as kitchen scraps (vegetable and fruit peelings), chemical-free grass clippings, and plant trimmings, and then add bokashi bran.

Start with a layer of the green compost materials. This initial layer serves as the base for your compost. Sprinkle a generous layer of Bokashi bran over the green compost materials. Keep layering until the bucket is full.

Ensure a diverse mix of materials for a well-balanced compost. Periodically press down the layers to eliminate too many air pockets and encourage anaerobic fermentation. Seal the composting container or bin to maintain the necessary anaerobic conditions.

50% Is The Ideal Homemade Bokashi Bran / Scraps Ratio

When using homemade bran, start with 50% and adjust as needed. As a minimum, adding about 1 tablespoon of bran for every inch of kitchen waste added to the heap is recommended.

You may use a wide range of compost mix, but large bones, thick branches, and other non-organic items are unsuitable for Bokashi composting and must be processed through alternative methods. 4

You can also consider grinding large bones into powder or boiling them to make a broth. These softened bones can then be added to the bokashi bucket.

Although perhaps not a household name, Bokashi bran is quickly becoming a favorite composting method for many home gardeners. This straightforward process requires just a few pieces of standard equipment. However, the real benefit of this method is its utilization of the anaerobic process (without air), meaning you can process meats and fish, further reducing household waste. Take a moment and check out the video below that explains how you can get up and running with this simple method.

Humble Tip:
When composting kitchen waste, adhere to the recommended guidelines of using 1-2 tablespoons of Bokashi for every couple of inches of food scraps to optimize efficiency.

Bokashi Tea As A Liquid Fertilizer, Nutrient Booster And Odor Reducer

Bokashi leachate is particularly beneficial by adding to the soil, as it delivers beneficial microbes to the root level, promoting plant growth, health, and vitality. It can easily be collected from the drainage plate of the composting system.

Crafting Bokashi Tea: Dilution Rate Of 1:100

Drain the liquid from your Bokashi composter into a separate container using the spout provided. Dilute the Bokashi liquid with water. The recommended dilution rate is around 1:100, but this can be adjusted based on the fluid volume and the plants’ sensitivity. Less sensitive plants may tolerate a lower dilution rate. 5

Application As A Nutrient Booster – Spray On Foliage

When spraying the tea, applying the diluted solution to the soil is recommended, as the foliage may be more sensitive to high acidity levels. The acidic nature of the leachate necessitates proper dilution before application.

It can also unblock slow and smelly drains and reduce the odor produced in the composting system. It enhances slower-producing compost piles and even acts as a weed killer, resulting in healthy soil. If you observe a smell in the composting bin, it can indicate that you need to add more Bokashi bran to the mixture. 6

Humble Tip:
When applying Bokashi compost tea as a fertilizer for your plants, the key is to start modestly and adjust the amount of Bokashi compost tea concentration as necessary to minimize the risk of over-fertilizing your greens.

Proper Disposal Methods For Bokashi Tea – Dilute Then Dispose

Before disposal, dilute the tea with water. This simple step helps distribute its nutrients more evenly and prevents any potential harm to plants if applied undiluted.

If you don’t have immediate use for the tea, consider pouring it down your sink or drainage system. The beneficial microorganisms can contribute to maintaining a healthy plumbing system.

However, you’ll want to avoid disposing of Bokashi leachate directly into storm drains or natural water bodies, as it may affect the local ecosystem.
