The market for "primeur" wine in the Bordeaux region allows producers to sell wine that is still in barrels. As with all experience goods, producers send quality signals to uninformed buyers. Using original data on Bordeaux wines, we show that the pricing behaviour of producers depends to a large extent on their reputation, and much less on short-term changes in quality (as measured by experts' grades). We also find that the primeur price has an informative role, since a 10 percent increase in primeur price leads to a 3 percent increase in prices on the market for bottled wine.
