Abstract:
In this study the ability of the droplet evaporation method (DEM) to discriminate between organic and biodynamic Sangiovese red wines was studied for the first time. The relationship between the sizing-parameters and shape-descriptors of the crystal structures and the chemical parameters of wines was evaluated, and the most significant correlations were found between the intensity of red color of wines with circularity (r = 0.90) and solidity (r = 0.94). Moreover the shape-descriptors allowed a discrimination between the organic and biodynamic Sangiovese red wines based on two kinds of structures: (i) needle-like and (ii) flower-like forms.
