Abstract
The article explores the effects of climate change on the copper content in Slovakian wines. The aim was to quantify the copper content in red and white wines of different vintages from southern Slovakia with the protected designation of origin "Južnoslovenská". The white wine varieties "Rizling vlašský" (RV) from the 2007 vintage and "Rizling rýnsky" (RR) from the 2016, 2020, 2021 and 2022 vintages as well as the red wine variety "Frankovka modrá" (FM) from the 2016, 2020, 2021 and 2022 vintages from the same region were analysed using ETA-AAS. The copper content in the white wines was between 183 μg/l and 255 μg/l, while values between 262 and 295 μg/l were found in the red wine variety "Frankovka modrá". The main aim of the study was to determine whether the increasing evidence of global warming could be linked to higher copper levels in wines. The available data suggest that there is a potential correlation between global warming and copper levels in wines.
