How information biases consumer sensory experience

Interesting report of two experiments showing how a priori or a posteriori knowledge of what one consumes may affect the overall sensory experience and preference.
There is a large body of literature showing that a priori knowledge creates expectations about what we think the product will taste like and hence how we will like it.

Marketing researcher Keith Wilcox and colleagues at Babson College in Wellesley, Mass., conducted a series of experiments showing that a little information can have the opposite of the desired effect if it is delivered after a taste test instead of before. In a nutshell, here’s what the study, to be published in the Journal of Consumer Research, says:

Can Chinese chocolate taste better than those incredibly delicious morsels from Switzerland, the center of the chocolate universe? Can cheap wine from India taste better than that pricy stuff from California’s Napa Valley?
