DESCRIZIONE

Discover the fascinating influence of soil on the rich flavors of Nero d’Avola red wines. This study explores how different soil types impact the wine’s polyphenolic and volatile composition. By analyzing six key soil parameters, the research reveals intriguing correlations between soil characteristics and the resulting wine’s chemical profile. Using advanced techniques like UV-Vis spectrophotometry, HPLC-DAD, and GC-MS, the study uncovers how elements such as cation exchange capacity and soil texture affect the concentration of various compounds, including anthocyanins and flavonols. The findings highlight significant differences in wines from different soils, offering a compelling insight into the delicate balance between soil and wine. Dive into the full study to uncover how the nuances of soil can transform the essence of Nero d’Avola wines.
