Angostura Bitter was created in 1824 by the German doctor Johann Gottlieb Benjamin Siegert in Angostura (now Ciudad Bolívar), Venezuela, with the aim of improving soldiers' digestion. The recipe combines carefully selected herbs and spices, resulting in an aromatic and intense bitter, used as an essential ingredient in classic cocktails such as the Old Fashioned and the Manhattan. Produced today by House of Angostura, based in Trinidad and Tobago, it maintains the artisanal tradition and original quality and is considered a world standard in the bitters industry.
