Suggesting types of wine for guests
If food is not to be served for a while, many people just choose what I call a meditation wine, one that you sip and savor for the quality of the wine and the taste you prefer. In this case, just suggest or provide them with the best-tasting wine value for the money.
That may be a wine that someone whose wine tastes you trust has recommended to you or a wine that is rated highly by one of the published wine experts. It does not necessarily have to be matched with food that will follow for which you will pair different wines.
