Vintage Champagne must age for at least three years before release under the appellation’s rules.
Vintage Champagne is produced from grapes harvested in a single declared year. The wine must spend at least three years aging in the bottle, including time on its lees, before it can be sold as vintage Champagne. Producers often age prestigious vintages much longer than this legal minimum.
This requirement differs from non-vintage Champagne, which has a shorter minimum aging period. Non-vintage wines blend harvests from different years to maintain a house style, while vintage wines express the character of one officially declared harvest.
The three-year rule is a minimum, not a recommendation for peak maturity. Extended lees aging can bring aromas and flavors associated with autolysis, including toast, brioche, and biscuit. Release timing therefore varies considerably among producers.
