Uneven flowering means Champagne’s long harvest, not one day
CIVC’s Sébastien Debuisson expects a drawn-out pick after frost, then heat, scrambled flowering. Heterogeneous bunches mean many village clocks, not one ‘Champagne day’.
Harvest posters make Champagne look like one date. The vines disagree every hot year — and 2026 is no exception.
Wine-Searcher quotes Sébastien Debuisson, CIVC research director: spring frost cut potential hard, then late-May and early-June swings upset flowering. Uneven set and millerandage (mixed berry sizes) point to uneven ripening across the appellation. Debuisson expects a long-winded harvest — villages and parcels on staggered clocks, not a single regional whistle on one morning.
Mini-concept: flowering is when vines set the year’s fruit. If cold and heat hit mid-flower, bunches do not mature together. Sparkling teams then pick by micro-timetable: protect acid here, wait a day there, rush a frost-scarred slope elsewhere. That is climate literacy written on a clipboard, not a slogan.
For drinkers, it explains why nonvintage blends matter. One early parcel and one late parcel can share a bottle only because the cellar is built to mix years and sites. A single-flavour can has no such toolkit when weather splits the map.
Pattern to keep: frost, then heat, then heterogeneous flowering. Champagne 2026 is many harvests under one famous name.
