It depends on several factors such as your price range, preference, and what you are going to serve it with.
Personally, I do not generally care for white wines so I will pair everything with a red wine. Some of my favorites are merlots, pinot noir, cabernet, and syrah.
I have had some excellent wines in all price ranges. Some value priced wines that I like are Robert Mondavi's Pino Noir Coastal, Jacob's Creek Shiraz, Blackstone 2002 Cabernet, and Blackstone Merlot.
My husband is actually the wine connoisseur in our family but when I am forced to make a wine decision and I don't recognize any of the available wines, I will always go with Robert Mondavi. His wines are available in a variety of price ranges and rarely do I find one that I just don't like at all.
