En primeur Wines, is a way for anyone to buy the most highly-sought after Bordeaux wines one to two years before they are bottled and released on the market. Each spring, thousands of wine professionals visit Bordeaux for the opening of the en 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 the most recent vintage. The prices are then released by the estate and wine merchants are allowed to buy their en primeur Wines. However, not just any wine merchant can buy these wines directly from the estates, only those who are registered within the Place de Bordeaux system, such as Millesima, can do so. Buying wine futures also allows you to buy the most highly demanded wines that may be virtually impossible to find when they are released on the market in a variety of different formats such as half bottles, magnums and larger-sized bottles.
