Refreshing kiln-leeched color

Many kiln-driers pretreat walnut with steam to darken the creamy, white sapwood, minimizing its contrast with the heartwood. That increases the yield of acceptably consistent wood color, but also leeches color from the heartwood, dulling it to a grayer shade.

Air-dried walnut, on the other hand, retains its creamy sapwood, but also its deep, chocolate heartwood and the variety of purple and reddish tones mixed in its grain.
