I like red wine.. I usually get stuck on one variety and switch back and forth every few months, been on a Zinfandel kick lately, also like Pinot noir, Sirah, and Cabernet Sauvignon.
The most I have spent on a bottle of wine would be in the $50-$75 range but my daily glass of vino would be one of the Calif. reds I get at the supermarket for $10-$20.

So I am at a fancy restaurant in Newport Beach and I take a peek at the (extensive) wine list... as I flip through the voluminous listing I see a few bottles in the $1000-$3000 range.

So I ask the wine experts here, what makes a bottle of wine worth that much?
At some point there must be a diminishing point of return... can a $3000 bottle be one hundred time better than a $300 bottle?

While I have your attention what is your favorite bottle of Zinfandel, Pinot noir, Sirah, or Cabernet Sauvignon in the under $100 range?
