t this point insert the corkscrew, set the lever against the lip, and slowly pry the cork upward, making sure that it doesn't begin to break or crumble. If it does, extreme caution will be needed to remove it without getting scraps inside the bottle. The cork should come away easily and cleanly, but don't pull it so forcefully that it makes a loud pop.
Use the moist lower end of the cork to clean away any residue around the top of the bottle and sniff it to make sure there are no obvious off odors. If there is any sign of cork scraps in the bottle, remove them by quickly pouring a tiny amount of wine into a glass.
Remove the cork from the corkscrew and set it aside within view so that the customer can check it on request.
Pour a small amount of the wine into a glass and quickly and decisively sniff and taste it. If there is any sign of a problem, tell the customer that you are getting another bottle and why - but don't seek permission, since that would reveal doubt. If the wine is right, grasp the bottle so that the label is evident and pour a small amount into the glass of the person who ordered - unless he indicates that someone else present should taste it.
