Abstract:
A method for evaluating the quality of grapes comprising the steps of:acquiring optical and calorimetric parameters of a sample of grape juice by emitting an optical signal and passing the optical signal through the sample of grape juice, wherein the sample of grape juice is obtained by pressing a sample of the grapes; detecting the optical and colorimetric parameters; correlating the detected optical and colorimetric parameters with correlation parameters previously stored in a memorized archive, the correlation parameters relating the optical and colorimetric parameters with organic and compositional characteristics of the sample of grapes, the organic and compositional characteristics including characteristics of color substances; determining a content of the coloring substances in the sample of grape juice; determining phenolic characteristics of the sample of grape juice based on the content of the coloring substances; and correlating a specific percentage content of the coloring substances with a defined and univocal quality and commodity class of the sample of the grapes.
