American walnut

American walnut is a hardwood prized for its rich brown colour and straight-to-wavy grain. It is a common choice for cabinetry and furniture where warmth and visual depth are priorities.

Character and behaviour

The heartwood ranges from chocolate brown to purplish-grey, often with darker streaks. Grain is usually straight but can be wavy or figured, giving cut surfaces a quiet visual interest. It machines and finishes well, producing smooth surfaces that feel substantial underhand.
