Evaluating the Greenness of Wine Analytical Chemistry: A New Metric Approach.

While the wine industry has already adopted some sustainable and environmentally friendly practices, special attention should be paid to the greenness of the analytical methodologies used. In this study, a new tool called "Green Wine Analytical Procedure Evaluation" (GWAPE) was developed to fulfill these "green" requirements. This framework offers a structured approach to evaluating the environmental impact of wine analysis processes, covering all the analytical steps from sample collection to the final results. GWAPE provides quantitative information, uses schematic representations, assigns varying levels of importance to green chemistry principles, and conducts detailed evaluations of hazard structures. Since wine analytical methods typically involve fewer highly hazardous reagents, certain criteria previously applied in green analytical chemistry should be integrated or omitted. In summary, GWAPE offers a customized and precise solution to help the laboratories of enology and the wineries assess their analytical methodologies' environmental impact. As an example of application, the proposed metric was used to evaluate the greenness of three different standard analytical methodologies to determine sugars in wine, showing good discrimination ability.
