looking for the right wine

[johnny21220]

I've just started to become interested in wine recently. I have tried some nice merlot's, pinot noir's and cabernets. I went to a wine specialty shop in my area Baltimore) and found they were not very helpful to me. There are so many different types of wines that I really don't know what to buy or where to start. I feel as though I'm limiting myself by not trying many of the different kinds of wine. Any suggestions on where to begin? I feel as though I'm going in blindly. Should I take a wine class before I dive in?
