Open Grain

A wood surface texture characterized by visible pores and vessel channels that create a tactile, textured feel. Open-grain woods like oak, ash, hickory, and walnut have large pores that remain visible even after finishing, giving the surface depth and character. Open grain can be highlighted with grain fillers, wire brushing, or cerusing (whitewashing), or it can be filled smooth for a uniform surface. It contrasts with closed-grain woods like maple and cherry.
