We need a little more info on what is in your cellar, and what you are drinking now. Also, are many of your wines home-made?
A Cabernet Sauvignon costing $30 or more should, in my opinion, age ten years (usually). A Pinot Noir costing $30 should age five years, some more, a few less. European versions tend to age a little longer, due to their higher acidity. I could elaborate on different varieties, but we need more info from you. What do you like to drink?
A good wine merchant will help a lot here too.
