So you're telling me there's a correlation between price and quality? Well, I guess that $1000 bottle of Lafite should really be sublime!
IMO, it's all about profit! There have been so many new collectors entering the marketplace over the last 15 years, buying anything and everything that's on the shelf with a fancy name, label, and bottle, that the profits were rolling in. Now, people are questioning, and that high end marketplace is saturated.
Buy what you enjoy drinking, take a bottle to your restaurant instead of buying off the wine list, but when you must, only buy a wine you know personally. Don't take a restaurants recommendation, unless you are familiar with the wine.
