MT01 - Maturity Trend - Maselli Misure
Real-time polyphenol analysis for red grape maturity assessment and optimized harvest decisions.
The MT01 delivers rapid, non-destructive measurement of phenolic maturity in red grapes using advanced UV-VIS-NIR spectroscopy. Within minutes of sample preparation, producers obtain precise indices for Total Polyphenol content, Tonality, Maturity Potential (MP%), and Phenolic Quality—enabling data-driven timing of harvest and tailored winemaking protocols. Exceptional repeatability and accuracy ensure consistent quality control across vintage seasons.
