Buga (Buža, Busio di Pirano) is a Slovenian variety of olives, widespread in the Istria region. Olives ripen very early, in early October. Ripe fruits have a rich purple-black color. They are small or medium, the shape is from round to irregularly ovoid. Buga olives are quite resistant to low temperatures and to the olive fly, but are sensitive to olive mould. This variety of olives is mainly intended for processing into oil. Olive oil has a fruity taste, slightly spicy, but almost not bitter. Like Belica, Buga is found in almost all Slovenian olive oil blends, for example, Sopotnik or Vanja Couvee.
