Bordeaux invented 'en primeur' to sell wine before it existed — and speculation broke it

En primeur — the practice of selling Bordeaux wine while it is still ageing in the barrel, 18 months before bottling — was invented in the 1970s as a way for châteaux to fund the harvest. The system was simple: critics tasted the young wine, gave it a score, and buyers committed to a price. The château got cash; the buyer got a discount.

The system worked for decades. But in the 2000s, speculation transformed it. Robert Parker's 100-point scores became the market's oracle: a high score could double a wine's price overnight. Chinese buyers entered the market in 2008, and prices for the top châteaux (Lafite, Latour, Margaux) tripled in three years. The en primeur campaign became a speculative bubble.

In 2012, the bubble burst. The top châteaux raised their en primeur prices above the market price of the bottled wine, and buyers walked away. The 2012 en primeur campaign was a disaster: unsold stock, collapsed prices, and a loss of confidence that took years to repair. The Bordeaux wine trade tells the story as the definitive case of a system that was invented to fund the harvest and destroyed by speculation.
