Vivid acidity is a hallmark of the 2008 vintage in Champagne, contributing to the decision by Richard Geoffroy, Dom Pérignon’s chef de cave from 1990 to the close of 2018, to release the 2009 last year, ahead of this year’s release of 2008. Cool conditions prevailed in Champagne during most of the 2008 growing season, but September’s bright and sunny weather during harvest rapidly turned what would have been an average vintage into one of the decade’s best.
