Binchotan gives the steadiest, cleanest heat and costs the most. Ogatan, made from compressed sawdust, gets close to that behaviour at a lower price and in uniform shapes. Lump charcoal lights fastest and burns hottest for a short time, with more smoke and flame. Which one a kitchen should use depends on how long the service is and how much control the cooking needs.
The three fuels
Binchotan is whole hardwood, carbonised slowly, fired at high temperature and quenched in ash. It is dense, hard and coated in pale grey ash. More on what binchotan is.
Ogatan is sawdust pressed into logs, usually hexagonal with a hole through the middle, and then carbonised. It is sometimes sold as sawdust binchotan or sawdust briquette charcoal. Because it is manufactured, every piece is the same size.
Lump charcoal is wood carbonised at lower temperature and cooled in the kiln, without the final firing. It is lighter, softer and black, in irregular pieces.
Side by side
| Binchotan | Ogatan | Lump charcoal | |
|---|---|---|---|
| Made from | Whole hardwood | Compressed sawdust | Whole wood |
| Lighting | Slow; needs a chimney or burner | Slow; needs a chimney or burner | Fast |
| Heat | Steady and radiant | Steady | High at first, then drops |
| Smoke and flame | Very little | Little | More, especially when lighting |
| Burn time | Longest | Long | Shortest |
| Ash | Low | Higher | Varies with the wood |
| Shape | Natural sticks, sorted by length | Uniform logs | Irregular pieces |
| Reusable | Yes | Yes | Partly |
| Price per kg | Highest | Middle | Lowest |
These are general characteristics. Actual figures depend on the wood and the producer, so ask for a laboratory report when comparing two suppliers. How to read one.
When binchotan is the right choice
- Yakitori, robatayaki and other cooking where food sits close to the coals and smoke from the fuel would mark the flavour.
- Open kitchens and tabletop grilling, where smoke and sparks reach the guests.
- Long services, where topping up the fire every half hour costs attention the cook does not have.
When ogatan is the right choice
- High-volume kitchens that want long, steady heat at a lower fuel cost.
- Grills where uniform logs are easier to arrange than natural sticks.
- Kitchens that can accept more ash in exchange for the saving.
When lump charcoal is the right choice
- Searing and short cooks that need high heat quickly.
- Cooking where a smoky, flame-grilled character is wanted.
- Home and occasional use, where waiting half an hour to light the fuel is not practical.
What about bamboo charcoal and briquettes?
Bamboo charcoal is made from bamboo rather than hardwood and is usually lighter and faster burning. Standard barbecue briquettes are pressed from charcoal fines with a binder; they are consistent and cheap, but they produce more ash and are not used in Japanese-style grilling.
Many kitchens use two
A common arrangement is to light a base of ogatan or lump charcoal to get the grill up to temperature, then cook over binchotan. Another is binchotan for the skewer station and ogatan for the larger grill. Mixing fuels this way keeps the cost down without giving up the clean heat where it matters.
We produce binchotan in three sizes. See the size range and laboratory figures.
