So many types of wine

[Catch 22]

If you are interested in learning more about wine, I would suggest doing some reading as well as tasting. I found Kevin Zraly's book (I think it's called "Windows On The World Wine Course", but I'm not at home as I write this, so I can't check)to be very helpful and informative. I'm sure others can recommend other books as well. I think that reading beforehand provides a good background that can help you make informed decisions about what wine to choose.
