In 1866, brothers and traveling merchants Simon and Pallade Violet opened a shop in Thuir with a few small barrels of wine. Simon created a unique recipe from a blend of fine Roussillon wines flavoured with plant extracts and enhanced with cinchona bark (quinine). At first called simply “Hygienic Tonic Wine with Cinchona,” the beverage was named Byrrh in 1876. According to one story, the name is a random invention: the letters B Y R R H were simply code letters attached to a few rolls of cloth stored in the haberdashery owned by the Violet brothers. The company expanded rapidly beginning in the late 1800s, and the Violet family built the expansive cellars that exist today. Caves Byrrh contain the largest oak vat in the world, with a capacity of over 1 million liters.
