En primeur, sometimes called wine futures, is a way for anyone to buy the most highly-demanded Bordeaux wines 1-2 years before they are bottled and released on the market. Each spring, thousands of wine professionals visit Bordeaux for the opening of the Primeur campaign. Over 150 of the top estates welcome journalists, buyers, importers, retailers and other wine professionals from all over the world to taste barrel samples of their latest vintage. Estates use the feedback they receive about the quality of the wine and vintage to estimate demand and set initial prices. In May, the estates release their prices and allow wine merchants to buy their future wines. However, not just any wine merchant can buy these wines directly from the estates. Only those who are registered within the Bordeaux area can do so. These 400 wine merchants or negociants as they are called in France, are known as the “the Place de Bordeaux” and represent the estate owners in promoting and distributing the wines all over the world.
