Bloom argues that essentialism plays a big role. We automatically believe that more expensive wine has a tastier essence, and that belief alters our sensory expectations. Those expectations, in turn, alter our perceptual interpretations, so that what we experience conforms to what we expect to experience. The essence of the thing has thus been confirmed: more expensive wine tastes better, even if the expensive wine is really Gallo Hearty Burgundy. This helps explain why so many food advertisements focus on the "essence" of the product, whether it's Coors being brewed from Rocky Mountain spring water, or Evian coming straight from the French Alps. The marketers know that the easiest way to increase our pleasure isn't by telling us how pleasurable the product is: It's by weaving an engaging story about essences.
