Lettie Teague knows wine. She has been the wine editor at Food & Wine magazine for almost a decade. The only question she is asked more than "Can you recommend a great wine for under $10?" -- great cheap white: Argiolas Costamolino Vermentino from Sardinia; great cheap red: Alamos Malbec from Argentina -- is "What is the best way to learn about wine?" After many years of fielding these questions, Lettie was determined to debunk the myth that learning about wine is hard. She decided to find just one wine idiot and teach him a few fundamentals -- how to order off a restaurant wine list without fear, approach a wine merchant with confidence, and perhaps even score a few points off a wine snob.
