About us

Hazelnut shell is a by-product of the harvest. We carbonise it into charcoal.

A nut, a shell, a second life

Giresun, on Turkey's Black Sea coast, has harvested hazelnuts for generations. What's left is the hard shell. Too tough to throw away, too much to leave lying.

We press and carbonise that shell into charcoal. No tree has to go, and no chemical binder comes near it. The material was already there. We turn it into fire.

What we stand on

  • 01

    No tree cut

    It all starts as shell left over after the nut harvest. A by-product, not a felled forest.

  • 02

    Odourless, tasteless

    No smell of its own, no aftertaste. You taste what you grill, or what's in the bowl.

  • 03

    Laboratory tested

    Every batch goes past the lab for fixed carbon, ash and moisture before it leaves the factory.

Made in Giresun, shipped from Enschede

Production sits in Giresun, where the shell comes from. Sales for the Netherlands run through Reis Food B.V. in Enschede, direct and in any quantity.
