Over the 30 growing seasons from 1991 to 2020, Champagne's vines saw on average 1,180 growing degree days between April and October. That puts it in Winkler region I, close in heat and rain to Rheingau, Marlborough and Willamette Valley. In a typical year about 366 mm of rain falls in the growing season, 49 mm of it in September.
Since 2000 the warmest season was 2018 (+34% against normal) and the coolest 2008 (-11%). The wettest harvest window was 2017, with 98 mm against a normal 49 mm.
The last 10 vintages (2016–2025) averaged +15% against the 1991–2020 normal, compared with +1% for 2000–2009; 8 of those 10 seasons were warmer than normal by more than 3%.
Growing degree days (base 10°C) for each season. The dashed line is the 1991–2020 normal (1,180 GDD) and the shaded band one standard deviation either side: about two years in three fall inside it.
Full bar: rain over the whole growing season. Dark part: rain in the harvest window (September). The line is the normal season total, 366 mm.
