Batch of ungraded Binchotan Charcoal

What is uncalibrated binchotan?

Chamarrel obtains its activated charcoal sticks from local producers in the south of Japan, with their ancestral know-how. They are obtained from a noble and very dense wood that can only be found in the south of the country of the rising sun.

For Western needs, the sticks are perfectly calibrated to meet the various constraints (quantity of water to be filtered, opening of containers, etc.). However, those that do not meet the requirements are not destroyed. As an ecological and zero waste online shop, we have decided to offer you these products for sale.

Sold loose, with no label and in their raw form, do not hesitate to use this natural and zero waste water filter to purify your tap water and thus say goodbye to your plastic bottles.


How can I use the Binchotan activated charcoal pack?

We offer set of 100 g of raw Japanese carbon. They are particularly suitable for professionals in the food industry (restaurants, bars, artisanal bakeries, food tricks, etc.), but also for individuals wishing to make a group purchase.

Binchotan charcoal is ideal for purifying the water needed by our bodies throughout the day. It is also perfect for obtaining purer and healthier water, especially for making hot drinks (coffee, tea, etc.) and will enhance their aromas.

Are you a large family? You also have the right to benefit from quality products. This is why this set of Binchotan charcoals allows you to always have purified water to offer on a daily basis to maintain your hydration.


How to use loose Binchotan charcoal?

After being burned, the Binchotan sticks are cooled in a mixture of sand and ash. These pieces are not graded and have not been cleaned, which is why they retain a whitish colour. This does not affect their ability to purify water. However, they should be cleaned carefully before use.


When you need to use your charcoal pieces, run them under cold water and scrub them with a vegetable brush or Loofah sponge to remove any white powder. Boil your charcoal sticks in water for about 15 minutes to activate them, then let them air dry. Once they are dry, you can then put one in each of the containers provided and fill them with water. Wait at least 8 hours before using the water.


As these Binchotan sticks are not calibrated, it is recommended to use 20 g per litre for good quality water, 30 g for average quality water and 40 g for poor quality water. To find out the quality of your water, contact your local council or here.


Do's and don'ts

Never exceed 50 g of activated carbon per litre of water and never leave your carbon in the same water for more than 48 hours. Finally, only use them with drinking water.

When you are not using your Japanese activated carbon continuously, let it dry and store it in a dry place.


Your questions about loose Binchotan 

Is loose Binchotan charcoal the same quality as the single unit?

Yes, they are simply pieces of coal that are not graded and therefore cannot be sold in the same way as the others. However, they come from the same trees and branches as those offered individually and have undergone the same drying and burning process. These Binchotan offcuts are therefore just as effective and safe as the individual pieces of activated charcoal.


Are all charcoal sticks the same size?

No, you can have various pieces (sticks, sections or pucks). Their diameter is less than 4 cm, or even 3.5 cm for the sticks. This means that they can fit into a bottle without any problem. For larger pieces, you can use glass bottles of tomato sauce, for example, to turn them into a pitcher at lower cost.


How many pieces of activated carbon are there in a batch?

This figure is variable. We guarantee 100g of Binchotan, but we cannot guarantee the number of pieces for the simple reason that they are not calibrated.

Original Japanese product:

Our Binchotan charcoal comes directly from Japan, from the prefecture of Wakayama, the birthplace of Binchotan.

It is made using the ancient method, in a traditional handmade kiln, with branches of Japanese Ubamegashi (holm oak) whose high density is essential for the quality of traditional Binchotan.



Controlled product:

Our Japanese craftsman is renowned for his expertise. He also has the authorizations to export his binchotan. These authorizations are provided by the Wakayama prefecture and are materialized by the yellow sticker which seals each shipment. This ensures the origin and reliability of the binchotan.

Once the Binchotan has arrived in France, at our request, it is tested by the CRIIRAD, a French association approved under the law of 1901 for the protection of the environment, which conducts studies and analyses in the field of radioactivity. These tests are renewed regularly.



Active support for the craft industry:

We have taken the decision to support handicraft production all the way to Japan.

Our activity supports a family that perpetuates the ancestral know-how that is the manufacture of the real Japanese Binchotan.

This is why Binchotan sticks are not regular but we assume this originality.



Product range:

We offer binchotan in sizes S, M and L (like the clothes) or in bulk by 100g (more economical but not "calibrated").

The "calibrated" sticks are all less than 3.5 cm (or even 3 cm) in diameter and are divided according to their weight (20% tolerance):

 - Flask 0.5 - 1 L: 20 g

 - Carafe 1 L: 25 g

 - Jug 1 - 2 L: 35 g

 - Fountain 2 - 3 L: 50 g

 - Carafe 3 - 5 L: 90 g


Use :

The dosage should be adapted to the quality of your water and your palate.

The Carafe stick is sufficient for a 1 litre carafe. Depending on the quality of your water, it may be necessary to switch to a Pitcher stick or even to add 2 Gourd sticks.


This stick can only be used on water that is already drinkable.

It should be handled with clean hands.


1) Put the stick under water and scrub it with a brush or loofah.

2) Plunge it into boiling water for about ten minutes

3) Take it out and let it dry in the open air

4) Once it is dry, place it in your carafe/bottle/flask (ideally in glass or stainless steel) and fill it with DRINKING water

5) Wait (ideally 8 hours or overnight). 

6) Your water is ready to be enjoyed.


Caution :

- Always handle the Binchotan with clean hands.

- Do not leave the Binchotan in the same water for more than 48 hours.

- If it is not used continuously, be sure to let it dry and then store it in an airtight container. It should then be brushed, sterilised (10 minutes in boiling water) and left to dry before being used again.

- Brush, sterilise (10 minutes in boiling water) and dry the Binchotan at least once a month (our craftsman recommends weekly).


Depending on how often you use it, the Binchotan is effective for +/- 4 months with average continuous use.

After that it can be crushed and used in the soil to enrich it, dried and used as an odour absorber (air, refrigerator) for example.
