What Is a Sommelier?

A sommelier is a trained beverage professional who helps guests choose, understand, and enjoy wine and other drinks. In a restaurant, the role can include building the wine list, managing the cellar, training staff, pairing wine with food, recommending bottles by style and budget, opening and serving wine correctly, and handling guest questions with confidence.

The word often gets reduced to “wine expert,” but that misses the hospitality part. A sommelier is not just someone who knows grape varieties or famous regions. The job is to turn that knowledge into a better guest experience at the table.

The daily work depends on the restaurant, but the core responsibilities usually cluster around three areas.

Area What it looks like in practice
Wine knowledge Understanding grapes, regions, vintages, producers, styles, service temperatures, and pairings.
Guest service Listening to what a guest likes, reading budget and occasion, and recommending without pressure.
Program management Buying wine, organizing the cellar, pricing the list, training staff, tracking inventory, and managing cost.

A junior sommelier may spend more time on service and floor support. A lead sommelier or beverage director may spend more time on purchasing, staff training, list strategy, and profit management. The title changes by restaurant, but the best sommeliers combine knowledge, taste, judgment, and care.

Not every sommelier is a Master Sommelier. “Sommelier” is a job or professional role. “Master Sommelier” is a specific credential earned by passing the highest level of the Court of Master Sommeliers exam path. Many excellent sommeliers never pursue that credential, and many candidates spend years building the skills required before they reach the top level.

If you are just starting, learn the role first. Understand wine service, taste classic styles, practice guest language, and build a study system. Certification can help later, but it works best when it formalizes real skill.
