Georges Delouis initially produced vinegar in Limoges, using raw materials sourced from byproducts of Bordeaux wine merchants. Over the centuries, Delouis developed raspberry vinegar, apple cider vinegar, mustard, and other condiments. In 1960, Philippe Delouis (the third generation) began exporting his products to various countries, successfully expanding into the American market. Today, Delouis has its own research and development department with skilled technicians and a dedicated laboratory.
