Does wine contain pesticides?
Quick answer
Traces of pesticides can be found in conventional wine: a PAN Europe study (2022) detected them in 26% of samples tested. Concentrations remain very low, 100-1,000 times below legal limits (MRLs). Organic and natural wines are virtually free of them.
Detailed answer
Grapevines are among the most heavily treated crops in conventional agriculture: they account for about 3% of European farmland but consume 20% of agricultural pesticides (Eurostat, 2021). Fungicides against downy and powdery mildew make up the bulk of treatments.
After winemaking, much of the residue is eliminated through fermentation, fining, and filtration. Nevertheless, traces remain. The PAN Europe association has conducted regular analyses: in 2008, 2018, and 2022, roughly 1 in 4 conventional wines contained at least one detectable residue. The most frequent molecules are boscalid, dimethomorph, and fenhexamid (fungicides).
Detected levels remain well below the Maximum Residue Limits (MRLs) set by EFSA (European Food Safety Authority). No peer-reviewed study has demonstrated a consumer risk at the concentrations found in wine. However, the 'cocktail effect' (simultaneous exposure to multiple low-dose molecules) remains an active research topic.
Organic wines (EU certified) are produced without synthetic pesticides. PAN Europe analyses show residues in fewer than 2% of organic wines, generally due to aerial drift contamination from neighbouring plots.
Biodynamic (Demeter, Biodyvin) and natural wines go further, excluding most plant protection products, including some allowed in organic farming (copper, sulfur). For consumers wanting to minimise pesticide exposure, organic or natural wine is the most relevant choice.
