Beirão is a Portuguese herbal liqueur that was first produced in the 19th century. Although the recipe is held secret, the drink is made by macerating twelve different botanicals. According to a widespread story, the history of the liqueur dates back to the 19th century when a Port salesman passing through Lousã fell in love with a daughter of a pharmacist.
They stayed in Lousã and started creating and selling various health remedies, including a liqueur for stomach pain which would in 1929 become the Beirão liqueur. In 1940, the company that produced the drink was bought by José Carranca Redondo who had great success into promoting Beirão into one of the most popular Portuguese liqueurs.
