How to Use Charcoal

Before using the charcoal pieces it is important to wash and boil the charcoal for 10 minutes to clean and sterilize the pieces. This process can be repeated weekly to help prevent bacteria contamination.

The product instructions for using charcoal generally varies anywhere from 1 to 4 pieces of charcoal per litre of water. This depends on the size of the item so check the instructions specific to your product. Personally I tend to put in considerably more as charcoal works by binding impurities to its carbon molecules. Having more charcoal makes the process more effective but providing more surface area for absorbing the impurities in the water. Going by the product instructions the immersion time is generally 8 hours. For myself I find that 12 hours overnight is what works best for me. It is important to understand that depending on the quality of the water and the quality of the charcoal the time required will vary. Obviously the longer you wait the better the results will be. I would recommend testing your water at different time intervals to find the ideal time that corresponds to the result you wish to attain.

  1. I use these. The downside is my tea leaves turn black after sitting around awhile. Of course it rinses off when I add water again.

    1. Do you mean sediments in the form of charcoal dust? I have not experienced problems with this myself. The charcoal pieces I have are a bit dusty on the surface but the inside is well compact. After a good wash and boil, no real problems.

    2. I think the carbon precipitates and settles on the tea leaves as they dry. This may be due to the already higher mineral content of my water. For example, I don't require Yixing pots, these add far too many minerals I don't need to the flavor. Porcelain is sufficient for me as it does not impart any more minerals. But the charcoal does a good job of eliminating chlorine odor.

    3. Interesting. With so many different variables/approaches/preferences out there, it is hardly surprising why the same tea can cause us to have such varied experiences. Definitely makes for more interesting exchanges. Thanks for sharing.
