Protecting crops without compromising grape and wine quality: a delicate balancing act
The registration of a new plant protection product does not end in the field. For the wine industry, one key question remains: what impact does the product have on the winemaking process and the organoleptic qualities of the wine?
At Staphyt, we support our clients in conducting winemaking studies to evaluate the fate of residues and the non-intentional effects of plant protection products. Our cutting-edge technical expertise ensures European regulatory compliance and biological efficacy for your registration dossiers.
Focus on our Winemaking & Residue Protocols
Our protocols are based on a strict application of CEB 143 methods and EPPO PP1/268 guidelines. For residue studies, we operate under the “Guidelines for residue data under Regulation (EC) No 1107/2009 (and former Directive 91/414/EEC) and Regulation (EC) No 396/2005”, as well as OECD guidance documents (Test No. 508, No. 97 and ENV/JM/MONO(2008)23).
This comprehensive framework allows us to cover the full analytical scope:
Field Trial Management: Management of application programs and grape sampling according to GEP (Good Experimental Practice) or GLP (Good Laboratory Practice).
- Micro-vinification: Implementation of controlled winemaking processes to evaluate the influence of products on fermentation kinetics and wine qualities (appearance, aroma, flavor).
- Expert Sensory Analysis: Identification of any changes in the appearance, bouquet, or flavor of wines through discriminative (triangle tests) and descriptive tests performed by qualified panels.
- Residue Transfer Analysis: Precise study of the persistence and degradation of molecules throughout the different stages of processing.
Ensuring consumer safety while preserving the identity of our terroirs: this is our daily mission alongside plant protection companies.
By combining field and laboratory expertise, we provide rigorous experimental setups adapted to both agronomic and oenological realities, a strategic challenge to reconcile agronomic performance, regulatory compliance, and finished product quality.
