Many wine buffs take a spare-no-expense attitude when it comes to ordering a glass of Chardonnay at a restaurant, suggests a new survey from Restaurant Sciences.

When out on the town, consumers who order wine by the glass tend to “select by palate rather than price,” said Restaurant Sciences, a Newton company that collects and analyzes data about food and beverage consumption in restaurants, bars, and food-service establishments. In compiling its wine-by-the-glass survey, the firm said it analyzed 10 million wine purchases.
