A sommelier is also known as a wine steward, and is someone who is trained and knowledgeable when it comes to all aspects of wine service, including wine and food pairing. The position is usually found at fine dining establishments, and is more specialized than the job of a wine waiter. A sommelier also works for the restaurant to procure and store wines, and see that the wine cellar is kept in good rotation. The employee will develop wine lists for the establishment and train other restaurant staff in the wine selections offered. A wine steward will work with the chef's team to pair and suggest wines that will go well with each item on the menu, and will also work on the main floor of the restaurant to speak with patrons to recommend wines that match their menu selections, taste preferences, and budgetary parameters. A broader role for the sommelier may include working with all aspects of the services offered by a restaurant. While anyone can claim to be a sommelier, becoming a certified sommelier requires coursework and an examination. The program takes approximately six months to complete and is offered by many different educational facilities. The exam is offered by the Court of Master Sommeliers. A sommelier should have excellent communication and customer service skills, and should be able to work evenings and weekends as required by the restaurant's staffing needs. As many wines originated in other countries and are named in other languages, a rudimentary knowledge of French is helpful when working as a sommelier.
