Another good alternative that can be considered when selecting wine to lay down, is to buy at the ‘En Primeur’ stage. This is wine still in the barrel (undergoing the aging process), before bottled or released on the open market. It is also referred to as ‘wine futures’ because the wine is bought in advance at a fixed price. It usually works out cheaper but no one knows how well the wine will mature. ‘En primeur’ tasting takes place every year in Bordeaux either at the end of March or the first week in April. For example, the ‘En primeur’ tasting of the 2001 vintage took place in March 2002. Most wines sold this way are classified growths or wines from very well known châteaux. ‘En primeur’ sales account for approximately 3-5% of the total Bordeaux wine production.
