We took the opportunity of being in the area to visit the Byrrh Caves in Thuir.

Byrrh is an aromatised wine apéritif made of red wine, mistelle and quinine. Created in 1866 and a trademark since 1873, it was popular as a French apéritif. With its marketing and reputation as a “hygienic drink”, Byrrh sold well in the early 20th century. It was even exported, despite the similarity of its name to “beer”, complicating sales in English- and German-language speaking regions.

Byrrh was sold in the United States until Prohibition. As of 2012, Byrrh has been reintroduced to the United States.
