Several members of the Fagaceae have important economic uses. Many species of oak, chestnut, and beech (genera "Quercus", "Castanea", and "Fagus", respectively) are commonly used as timber for floors, furniture, cabinets, and wine barrels. Cork for stopping wine bottles and myriad other uses is made from the bark of cork oak, "Quercus suber." Chestnuts are the fruits from species of the genus "Castanea." Numerous species from several genera are prominent ornamentals, and wood chips from the genus "Fagus" are often used in flavoring beers.
