Why Wood Vinegar?

Wood vinegar is natural, gentle on the
environment, and cost-effective. The
materials needed to produce wood
vinegar, such as bamboo, clay, and wood,
are readily available in even the most
remote areas of Asia.


Making wood vinegar is an exciting way to
teach students about practical science
topics. This knowledge can help them
prosper in their future careers.

 The production of wood vinegar is cost- effective, takes only one day and offers a
versatile range of beneficial applications that
are gentle on the environment.


  • Use Charcoal product for cooking. Charcoal made from wood vinegar produces cleaner, safer smoke.

  • Kill pests by applying a 1:20 ratio to the soil.

  • Kill weeds by applying a 1:50 ratio to the soil.

  • Prevent stems and roots from rotting
    by applying a 1:100 ratio.

  • Prevent pests and mold while
    accelerating plant growth by applying a
    1:200 ratio to the soil.

  • Prevent plant lice by applying a 1:400 ratio to the plant.

  • Enhance fruit growth by applying a 1:500 ratio to forming fruit.

14 Steps to Make Wood Vinegar in 3 Months

Step 1

  • Get a 200L metal Tank and cut the lid off one end.
  • Cut a 20 cm x 20 cm
    square hole at the bottom of the lid

Step 2

  • Cut a 10 cm diameter circular hole on the other side of the tank.

Step 3

  • Attach an asbestos joint to the 10
    cm hole as shown in A of diagram.
    Then, attach an asbestos pipe to
    the joint.

Step 4

  • Make a bamboo pipe by hollowing out a 4m bamboo stalk with a metal pole. Cut one end of the pipe at an angle.

Step 5

  • Cut a notch 30 - 50cm away from
    the angled end of the pipe. This
    notch will allow wood vinegar to
    drip out later on in the process.

Step 6

To produce charcoal and
wood vinegar:

  • Load three short logs in the kiln
    horizontally to promote air flow.
  • Stack logs from smallest to
    largest and perpendicular to the
    3 short logs as shown in the
    picture to the left. This allows
    all logs to fully burn.

Step 7

  • Seal the kiln lid in place with a layer of clay about 5 cm thick. Proceed while the clay is wet.

Step 8

  • To build a fireplace, put 4 bricks
    around the 20 cm square hole in
    the lid. Seal with clay.


Step 9

  • Start and maintain a fire slightly inside the brick fireplace. Wait approximately
    2 hours until a strong white smoke
    emerges from the asbestos pipe.


Step 10

  • Attach the angled end of the bamboo
    pipe to the asbestos pipe at point C.
    Seal with clay, making sure the
    notch is facing downward.


Step 11

  • Wrap the length of the bamboo pipe
    with cool, damp cloths to aid in the
    condensation of raw wood vinegar.
    Hang a collection bottle at the notch
    to capture the product.


Step 12

  • Maintain the fire and dampness of
    the cloths. The raw wood vinegar is
    finished producing when the droplets
    turn black, indicating that tar has formed.


Step 13

To make charcoal:

  • Remove the collection bottle and the bamboo pipe.
  • Place a small clay pot on the
    opening of the asbestos pipe and seal
    any remaining openings with clay.
  • Stack two bricks in front of the entrance and seal with clay
  • Wait 8 hours for charcoal to form


Step 14

To purify raw wood vinegar:

  • Let the wood vinegar sit for 90 days
    and settle into 3 layers.
  • Extract the middle layer of wood
    vinegar with a syringe.
  • Dilute the wood vinegar depending
    on its purpose.
