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
Wood Vinegar for Organic Agriculture
- Cut a 10 cm diameter circular hole on the other side of the tank.
- Attach an asbestos joint to the 10
cm hole as shown in A of diagram.
Then, attach an asbestos pipe to
- Make a bamboo pipe by hollowing out a 4m bamboo stalk with a metal pole. Cut one end of the pipe at an angle.
- 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.
To produce charcoal and
- 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.
- Seal the kiln lid in place with a layer of clay about 5 cm thick. Proceed while the clay is wet.
- To build a fireplace, put 4 bricks
around the 20 cm square hole in
the lid. Seal with clay.
- Start and maintain a fire slightly inside the brick fireplace. Wait approximately
2 hours until a strong white smoke
emerges from the asbestos pipe.
- 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.
- 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.
- 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.
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
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.
