BINCHOTAN CHARCOAL

Binchotan is produced by firing in a sealed kiln at a low temperature for a long period – up to 4 days. Oxygen in the kiln is reduced in order for the carbonisation to take place. It is then refined at very high temperature – over 950°C – for a short period. After firing it is removed from the kiln and smothered with sand, ash and soil giving it’s distinctive white appearance. The result is a highly dense charcoal with a carbon content of approx 93-95%. The binchotan from the Kishu region is said to have the best binchotan with a carbon content of 96%.
