f a wine is not approved by the costumer, for whatever reason, don't contest the decision but offer to get another bottle of the same wine or, if you are certain that the taster is at fault, suggest another wine.
If approved, after a sniff or a taste, begin serving, following the usual etiquette of ladies first. Serve from the right of each guest, filling glasses to prescribed levels and keeping the label in view. End each pour with a gentle half twist of the bottle to remove any drips from the lip. A clean white napkin should be held in the left hand to avoid any drips on the tablecloth. Conclude the first pouring by filling the taster's glass to the right level.
During the meal, check the level of wine in the glasses frequently and provide refills before any is empty. Before the bottle is empty, ask the person who ordered if he would like another of the same or another wine. If there is a change of wine, place clean and appropriate glasses around and repeat the serving procedure.
Remove the preceding glass only with each guest's consent.
