A birch is a thin-leaved deciduous hardwood tree of the genus Betula (/ËbÉtjÊlÉ/), in the family Betulaceae, which also includes alders, hazels, and hornbeams. It is closely related to the beech-oak family Fagaceae.

For this reason, it usually looks best in natural finishes and is more popular in traditional kitchens. Birch wood generally exhibits a straight and uniform grain.
