Angostura bitters is a concentrated bitters, or botanically infused alcoholic mixture, made of water, 44.7% ethanol, gentian, herbs and spices, by House of Angostura in Trinidad and Tobago. It is typically used for flavouring beverages or (less often) food. The bitters were first produced in the town of Angostura (Ciudad Bolívar, Venezuela) (hence the name), and do not contain angostura bark. The bottle is easily recognisable by its distinctive over-sized label.
