Cubeb (Piper cubeba) is a plant in genus Piper, cultivated for its fruit and essential oil.
The fruits are gathered before they are ripe, and carefully dried.
Commercial cubebs consist of the dried berries, similar in appearance to black pepper, but with stalks attached – the "tails" in "tailed pepper".
The dried pericarp is wrinkled, and its color ranges from grayish-brown to black.
The seed is hard, white and oily.
