Wine and Pesticides: What to Know About Chemical Residues in Your Glass
The topic of wines and pesticides is increasingly central to the debate on food safety and wine quality. Although most conventional wines comply with legal limits, recent analyses have highlighted the presence of chemical residues in a very high percentage of samples analyzed.
According to tests conducted in 2025, traces of pesticides were detected in 94% of the conventional wines examined, with the presence of up to 18 different chemicals. Concentrations are often higher in red wines than in white wines, partly due to longer maceration times that increase contact with the skins.
Chemical residues in wine: fungicides and TFAs under observation
Among the substances most frequently found in tests are various fungicides used in intensive viticulture. The most common are:
- Folpet
- Boscalid
- Fluopyram
- Fluopicolide
In recent years, TFA (trifluoroacetic acid), a byproduct of PFAS, has also caused particular concern. This compound, increasingly present in European wines, derives from soil and groundwater pollution, not exclusively from direct agricultural activity.
It is important to note that almost all wines on the market fall within the maximum limits permitted by European regulations. Furthermore, the fermentation process acts partly as a natural filter. However, expert criticism focuses on the possible interaction between multiple substances present simultaneously, so-called “”residual mixtures.””
Organic and Natural Wine: An Alternative to Synthetic Pesticides
When comparing conventional wine and organic wine, significant differences emerge. Vines grown according to organic regulations do not use chemically synthesized pesticides, herbicides, or insecticides, but only natural substances.
This approach drastically reduces the risk of contamination from artificial residues, although a minimal possibility of cross-contamination from neighboring vineyards may still exist.
In this scenario, organic and natural wines today represent the safest choice for consumers wishing to limit their intake of synthetic chemical residues. In addition to protecting health, this choice supports more sustainable and environmentally friendly agricultural models.
For those who care about the combination of wine and pesticides, choosing organic or biodynamic production means prioritizing transparency, quality, and lower environmental impact, without sacrificing the pleasure of a glass of wine.
