I've been slowly learning about wines for the past few years. Today I interviewed for a position in a restaurant that requires (unbeknownst to me) an extensive wine knowledge. I was honest in saying that I don't know much about wine. The manager is willing to give me a chance as I have other applicable experience.
Can you help me? What are the most important things that I should know about wine (and beer)? What can I learn quickly that will impress the restaurant staff?
Any tips are greatly appreciated.
