If they aren’t winemakers, most people who work professionally in the wine industry are sommeliers.
The wine industry in the U.S. alone is a huge industry valued at close to $20 billion and employing some 2 million people. Within the industry are dozens of occupations from finance and human resources, to viticulture and quality control, to sales and marketing, to education and communications. Most of these jobs don’t require a sommelier certification. That said, the people who buy wine professionally and create and manage wine programs in the hospitality industry (sommeliers), are a key part of the wine industry. Currently, there are some 11,000 people who have passed the Certified Sommelier Examination and 172 who are certified at the highest level, as “Master Sommeliers” by the Court of Master Sommeliers in the Americas.
