We have a wine cellar, so we likely are at the upper range of normal. Our average wines cost (purchased directly from wineries and rarely at a wholesaler near our home):

Pinot Noir: $80-100
Chardonnay: $75-90
Syrah: $85
Cabernet/Cabernet blends: $250-300
Merlot/Merlot blends: $90-110
Malbec: $75-125

We drink mostly New World wines, and we prefer aged wines (though my husband prefers younger Chards/Pinots than I do). Wines that age well tend to be much pricier, of course.

If you like more freshness or acidic wines or more fruit in your bouquet/flavor, then younger wines are the better way to go, as they are usually less expensive. If you like big powerful wines but want to avoid the harsher tannins and sulfites that often cause headaches, then I'd recommend spending a little more as you can afford on Cabernet type wines...or consider Syrahs that can be as big but not nearly as expensive.
