HORIBA’s Veloci Wine Analyzer is uniquely equipped with patented simultaneous Absorbance-Transmission and excitation-emission matrix (EEM) technology (A-TEEMTM) which provides rapid access to a wide range of parameters important to commercial wine processing and quality characterization. The Veloci Wine Analyzer acquires a complete UV-Vis spectrum including the industry standard Absorbance wavelength values at 280, 420, 520 and 620 nm which are important to evaluate a wine’s phenolic content, Hue and Intensity. The Veloci Wine Analyzer also reports the Transmission spectrum which can be used to determine the CIE Lab Tri-Coordinate Color Descriptions. Most importantly, the Veloci Wine Analyzer reports a NIST-traceable EEM which can be evaluated using multivariate statistics. EEM analysis fingerprints yield qualitative and quantitative composition of key flavor and color determinants that are not discernible with simple Absorbance or Transmission data analysis. Together the Absorbance, Transmission and EEM data can be used to evaluate lot-to-lot, regional, and varietal characteristics, as well as sense the effects of oxidation and sulfite treatment, thus making the Veloci Wine Analyzer a valuable tool for industrial wine characterization.
