These are only the third and fourth release of their Prestige Cuvée, Cuvée Sir Winston Churchill, in Jeroboam, following the 1988 and 1999: the ultimate marriage of quality and quantity. Across all four vintages, just in excess of 500 jeroboams have ever been produced. The vintage jeroboams are hand-labelled and individually numbered- the 2012 from 1 - 198. In Champagne, the jeroboam is the largest format (3l) where the secondary fermentation takes place in bottle. Champagne enthusiasts have long championed the merits of the jeroboam; the larger the format, the longer the fermentation, the greater the complexity.
