Over the 30 growing seasons from 1991 to 2020, Jerez's vines saw on average 2,610 growing degree days between April and October. That puts it in Winkler region V, close in heat and rain to Priorat, Stellenbosch and Hunter Valley. In a typical year about 203 mm of rain falls in the growing season, 26 mm of it in August–September.
Since 2000 the warmest season was 2023 (+10% against normal) and the coolest 2002 (-7%). The wettest harvest window was 2008, with 67 mm against a normal 26 mm.
The last 10 vintages (2016–2025) averaged +4% against the 1991–2020 normal, compared with +1% for 2000–2009; 5 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 (2,610 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 (August–September). The line is the normal season total, 203 mm.
