One term that many wine drinkers ask about is 'Sommelier'. The term can now be seen applied to tequila, beer, chiles, and even chocolates. Usually, however, 'Sommelier' is reserved for its original definition - a specialist wine waiter or wine steward. A wine steward in a restaurant. A rather dry definition.
Some restaurants also have the sommelier in charge of actual wine cellar stocking and replenishing.
Sommeliers are in charge of the interesting wine-serving ritual, involving the showing of the cork, the pouring of the sample, and the remaining wine pouring. Many countries have official organizations of Sommeliers, which overlooks the testing and certification of Sommeliers. There are also fun contests where wine lovers test their skills against each other. One such is the Sommelier Mondial . The 10th running just finished taking place in Montreal, Canada.
