Secondly, this is unfortunately not a great wine forum. Don't know why and I don't know if there is a better one. But my guess is that there is so much wine in the world and it changes every year that it would be hard to have a good forum. The wines in my local shop will probably not have the same wines in yours.
"Wine Spectator" is a good magazine to give you some ideas but remember they are not always right and alot of their suggestions are hard to come by. Hugh Johnson's "Pocket Guide to Wine" is a good starting book.
But as my wine mentor once told me, "The only way to learn about wine is to drink it". Don't pidgeon hole yourself into a type on wine, sweet or dry, red or white. Try everything with an open mind. Great wine is great wine.
