Soon to be waiter know NOTHING about wine!

[Zinner]

Just to throw something into the mix...
There's a book called Exploring Wine by Steven Kolpan, Brian H. Smith and Michael A. Weiss that does cover wine service. These guys are wine educators at The Culinary Institute of America, so they spend their time training chefs and sommeliers.

In fact the books covers a wide territory from wine production(new and old world), tasting,wine and food to wine and health. I find it reader-friendly and informative, so you might want to take a look. I'd recommend it to both wine service folks and consumers.

It is published by Van Nostrand Reinhold.
