If you are hosting a dinner and are unfamiliar with the many different types of wine and how to pair them with food, ask the sommelier, if there is one available, for recommendations. If there is not a sommelier available, ask one of your guests who is familiar with the wines to make a selection.
We cannot be experts on all subject matters, so the guest would most likely be pleased to know you recognize their wine knowledge and respect their wine selection. It’s better to ask for an expert’s help than have the expert question your decision.
