[2][1] Beirão is a Portuguese adjective meaning "from Beira", the name of a former province in Portugal, currently contained within the country's Centro region.

In the late 19th century alcoholic beverages were no longer qualified as medicinal but the liqueur was kept in production in a small factory owned by the son-in-law of the original producer.

[4] These first billboards, picturing a simple sign-board with "Licor Beirão, the liqueur of Portugal" on a country landscape, became an icon of Portuguese advertising.

A later billboard, picturing an American style majorette, wearing very short and tight red T-shirt and breeches, and showing her belly, had to be withdrawn because it was not well accepted due to the girl's unorthodox lack of clothing.

[6] The liqueur is still produced and bottled at Quinta do Meiral, according to the original secret recipe, by double distillation of 13 different aromatic seeds, herbs and spices.
