If so, the waiter will remove any unnecessary wine glasses and make certain that the proper glass remains for you to use. If you should choose to have more wine as the meal progresses, the waiter will bring the appropriate glasses to you automatically. So while it is comforting to recognize wine glasses when you see them, their specific and proper usage is left to the completely knowledgeable wait staff. If it is red wine, hold the glass by the bottom of the goblet. The reasons are practical ones.
White wine is served more chilled than red-holding the glass by the stem helps it to remain chilled.
Red wine is served warmer than white-the heat of your hand around the goblet will not diminish the wine's bouquet. Order something moderately priced unless your host indicates otherwise. Stay with something relatively easy to eat. Don't take forever deciding on your choice. This is one of those rare occasions that you needn't be concerned with any part of the bill.
