This kind of experiment has been done before -- serving water from a garden hose in fancy spring water bottles, serving fast food on a plate in a restaurant, etc. People pretty much always assume the presentation is accurate. They think they can taste the melting glaciers in the hose water, and that the salad from Wendy's is a healthy, high-quality item was lovingly prepared by a master chef in the kitchen just for them.
My own personal experience is that wine + food is most interesting. Both the wine and the food can change their taste substantially when paired well. But it's very rare that I can find a wine that I can stand in quantities to drink without food.
