Do we have to know a wine's price to know if we like it?

        I blogged the other day about whether it’s moral or ethical or whatever to secretly serve yourself better quality wine than you serve your guests -- if you know a lot about wine and they know too little to appreciate the good stuff.
       Faithful reader Kassie had an interesting comment, posted here saying she has a friend who always tells her the price of the wine she’s drinking so she can pay proper attention to it if it's expensive.
       Sad, but true. In a recent casual experiment, a wine magazine found that a wide range of people liked a wine better when they had been told it was $90 than when given the same wine and told it cost $9.
       Money talks, I guess.
