• Compendium of International Methods of Wine and Must Analysis

The 2025 Compendium of International Methods of Wine and Must Analysis, published by the International Organisation of Vine and Wine (OIV), serves as a comprehensive regulatory and scientific guide for the vitivinicultural industry. It outlines standardized physical, chemical, and microbiological procedures for examining wine, must, and grape-based beverages to ensure consistency in global trade. The document details specific analytical protocols, such as pycnometry for density measurement and enzymatic methods for sugar evaluation, while categorizing techniques based on their regulatory status. Furthermore, it provides technical frameworks for laboratory quality assurance and precise reporting standards, including requirements for apparatus and reagents. By establishing these harmonized benchmarks, the OIV facilitates legal transparency and technical cooperation between member nations and international bodies like the European Union.
