While visiting the 8th arrondissement in Paris, we ventured into Boutique Maille on the Place de la Madeleine. Maille is a French mustard and pickle company that dates back to 1747; it is famous for its Dijon mustard and cornichon. The history of Maille is very interesting. Antoine-Claude Maille, a vinegar merchant, gained renown in 1720 when la peste (the plague) ravaged Marseille. His invention of the “Vinaigre aux Quatre Voleurs” (Four Thieves Vinegar) and its antiseptic qualities ended up saving the lives of many Marseillais from the disease. His son, also named Antoine-Claude Maille, opened a shop in 1747 in Paris. Because of the high quality of his ingredients, he soon became the official supplier of vinegars and mustards to Louis XV of France. Today, while Maille still makes award-winning Dijon mustard, Maille also offers different types of mustard, oil, and vinegar.
