What Is a Sommelier? Uncorking the Role of a Restaurant Wine Expert

In the world of fine dining, few roles exude the same mystique and elegance as that of the sommelier. If you've ever dined at a high-end restaurant and been guided through the wine list by a knowledgeable, poised professional, you've likely encountered a sommelier. But what is a sommelier, exactly, and what makes their job so essential to a successful restaurant experience?

This article explores the role of a restaurant sommelier, how they influence the guest experience, their impact on the restaurant economy, and what it takes to pursue this prestigious career.

What Is a Sommelier in a Restaurant?

At its most basic definition, a sommelier is a trained and certified wine professional, typically working in fine dining establishments. The term originates from France, and in traditional usage, it referred to someone who managed wine cellars. In modern settings, the sommelier’s responsibilities have expanded far beyond merely recommending a red or white wine.

A restaurant sommelier is not just someone who knows wine—they are experts in wine and food pairings, global wine regions, varietals, service etiquette, and even the science of tasting. They are also increasingly responsible for curating beverage programs that include spirits, cocktails, sake, and even craft beer, depending on the establishment.

What Does a Sommelier Do in a Restaurant?

So, what does a sommelier do in a restaurant on a daily basis?

Wine List Curation
One of the key tasks of a sommelier is building and maintaining the restaurant's wine list. This involves selecting wines that match the cuisine, the restaurant’s brand, and its target clientele. Sommeliers often work closely with chefs to create a list that enhances the overall dining experience.

Wine and Food Pairing Recommendations
When guests dine in a fine restaurant, they may ask the sommelier for advice on which wine pairs best with their meal. This is where the sommelier shines. They assess the flavors, textures, and aromas of both food and wine to recommend ideal pairings that elevate the dish and the drink alike.

Wine Service
A professional restaurant sommelier doesn’t just recommend wine—they serve it too. From presenting the bottle and opening it with finesse to pouring it correctly and maintaining the right temperature, wine service is an art form.

Staff Training
A sommelier is often responsible for training the front-of-house staff about wine basics. This ensures that servers can answer basic wine-related questions and assist customers even when the sommelier isn’t available.

Inventory Management
A significant part of a sommelier’s job involves managing wine inventory. This includes ordering, stocking, organizing the wine cellar, and reducing waste or spoilage.

Guest Experience Enhancement
Beyond their technical knowledge, sommeliers are expert communicators. They gauge a guest’s preferences, offer approachable suggestions, and provide an educational yet welcoming experience that enhances the meal and creates a lasting impression.

What Is a Sommelier Job Like?

The sommelier job is a unique blend of hospitality, sales, artistry, and science. It requires an in-depth understanding of wine regions, grape varieties, vinification processes, tasting techniques, and food science.

This job also requires people skills and adaptability. A good sommelier can just as easily recommend a $30 bottle as a $300 one, depending on the guest’s budget and tastes. There is no ego—only a passion for sharing the joy of wine.

What is a sommelier job also depends on the size and type of restaurant. In a Michelin-starred establishment, the sommelier may work with a team. In a smaller fine-dining venue, they might manage the wine list single-handedly while also assisting with general restaurant operations.
