Licor 43

Licor 43, or Cuarenta y Tres , is a Spanish liqueur, made in Cartagena, Spain. Licor 43 was invented in 1946 by the siblings Diego, Angel, and Josefina Zamora, along with Emilio Restoy, Josefina's husband. The Licor 43 website states they based their recipe on the Liqvor Mirabilis (marvellous liquid), a golden, aromatic elixir produced and infused from local fruits and herbs in Carthago Nova during the 3rd century. Liqvor Mirabilis was encountered by the Romans when they conquered the region in 209 BC; despite the Romans banning its production and consumption, the Carthaginians continued producing in secret. This legend served as the inspiration for the Zamora's invention of Licor 43. The name of the modern-day liqueur originates from its use of 43 different ingredients; while its recipe is a closely guarded secret by the Zamora family, it is known to contain citrus and fruit juices, and to be flavoured with vanilla, among other aromatic herbs and spices.
