Abstract

This study investigates the critical relationship between soil characteristics, trace element concentrations in Nebbiolo grapes, and the resulting wine quality, emphasizing the importance of terroir in winemaking. Italy, particularly the regions of Piedmont, Lombardy, and the Aosta Valley, is home to Nebbiolo, a prestigious grape variety known for its depth and aging potential in wines like Barolo and Barbaresco. The research focuses on seventeen grape and wine samples, highlighting how soil mineral composition could affect grape composition and wine characteristics. The analysis employed ICP-AES (inductively coupled plasma atomic emission spectrometry) to measure trace elements such as Al, Ba, and Mn, linking their concentrations to the soil’s geological properties. Elements were categorized into three groups based on their origins—natural soil contributions (Al, Ba, Li, Mn, Mo, Sr, Ti), those influenced by production cycles (Ca, Mg, K, Cu, Zn, Fe), and artificial sources (Co, Cr, Ni, V)—asserting that the first group serves as the most reliable indicators for tracing wines back to their vineyard origins. By establishing a chemical fingerprint for Nebbiolo wines, this research aims to enhance their authenticity and market value while providing insights into the intricate interplay between soil, grape varietals, and winemaking practices and contemporary challenges like climate change and evolving market demands.
