Having Customers Share The Perception Of Quality Differences - One Century Of Debates About Quality Assessments On The French Wine Market

The wine market is a pretty paradoxical research object for the economical and marketing studies. In France alone, every year, hundreds of thousands of new brand differentiated products are marketed. How can so many brands survive to any rationalization process? One could think this situation to be tied to a kind of French paradox, but the number of wine brands is also increasing in all wine producing countries whether old, like Spain or new as US. Furthermore whereas most of the market theories explain the existence of markets thanks to the happy meeting of a demand with a corresponding supply, how could we explain the growth of the so called quality wine market, where it is so difficult to find two drinkers, even to expert drinkers, agreeing about the quality of a wine, ruining therefore the possibility of existence of any demand. The wine market is an interesting field case that helps us revise some of our most widely shared hypothesis on the empirical functioning of the markets.

During this period, faced with repeated crisis, the wine market actors did not stand without reaction. Next to the limitation of the production, the wine quality emerged as a major stake during all the 20th century. In order to help its recognition, it became first labelled with origin denomination labels. But soon, new difficulties led to reconsider the quality labels efficiency. During the period considered, each new crisis brought in the same way critics of the old measures and new solutions. So, difficulties after difficulties, ever larger collectives proposed and set up ever more adapted procedures for the marketing of the wines. So the 20th century has seen the coming out of a series of procedures aimed at facilitating the quality recognition of the wines. But step by step, the authors acknowledged as able to define quality were changing, such as quality itself, and new market organisations appeared. Nevertheless, far from sweeping away the old procedures, the new solutions cohabited with them making the wine market appear today as a complex multilayered sandwich of market procedures that fostered the development of a market of hundred of thousands of wine
