A sommelier serves as a professional wine taster, although the term also refers to someone responsible for serving wine at an establishment. The earliest known usage of the word "sommelier" was in 1829, and it originated from the French word "soumelier," which refers to someone who transports supplies, as noted by Merriam-Webster.
A sommelier often works in fine restaurants and may help prepare the restaurant's wine list, overseeing which wines go with the food served. This professional can undergo extensive training and may hold a certificate from an organization such as the North American Sommelier Association, which offers the Master Wine Taster credential. Understanding the anatomy of the human tongue, winemaking, wine scoring and tasting methodology are important skills for sommeliers, as stated by the North American Sommelier Association.
