That's tough. Do you drink yourself? So if you had extras, would they be used?
I'd do a couple bottles each of red, white and champagne. One cab, one Pinot noir, one Sauv blanc, one Chardonnay, one champagne, one prosecco. Walk down the aisles at total wine and pick something the staff members recommend. I'd get a couple six packs of beer, a local beer like D.C. Brau and modelo, which is popular. Maybe a six of seltzer or cider.
