After a fruit ripening of five to six months, the one-seeded fruits appear, which botanically are berries. They stand together in grape-shaped inflorescences. Date berries are oblong-oval in shape and grow up to seven centimeters long. Ripe berries are recognized by their light to dark brown, sometimes golden yellow or bright red coloration. A tree can yield up to 100 kilograms of fruit, but bears only once every two years. After harvesting, the dates are pitted and boiled in water. Finally, they are pressed, filtered and thickened into syrup.
