En primeurとは 意味・読み方・使い方

En primeur or "wine futures", is a method of purchasing wines early while a vintage is still in a barrel, offering the customer the opportunity to invest in a particular wine before it is bottled. Payment is made at an early stage, a year or 18 months prior to the official release of a vintage. A possible advantage of buying wines en primeur is that the wines may be considerably cheaper during the en primeur period than they will be once bottled and released on the market. However, that is not guaranteed and some wines may lose value over time. Wine experts, like Tom Stevenson, recommend buying en primeur for wines with very limited quantities and will most likely not be available when they are released. The wines most commonly offered en primeur are from Bordeaux, Burgundy, the Rhône Valley and Port, although other regions are adopting the practice.
