If wine is something you're interested in, but you've found intimidating or opaque or whatever, I can't reccomend
Windows on the World by Kevin Zraly highly enough.
It is a book that is absolutely directed at the new or inexperienced wine consumer for the express purpose of helping them become more knowledgable. It's well written, clear, approachable, not overwhelming, and provides a really good foundation if you find the subject interesting.
