Special Issue Information

Dear Colleagues,

This Special Issue of Molecules aims to showcase recent advances and innovative approaches in wine chemistry and analytical science. Wine represents one of the most chemically complex beverages, where interactions among thousands of volatile and non-volatile compounds determine its aroma, flavor, color, and overall quality. Understanding these compounds and their transformations is essential for improving winemaking practices, ensuring authenticity, and enhancing sensory perception. We invite original research papers, communications, and reviews addressing the characterization, quantification, and functionality of key wine constituents, including phenolics, thiols, esters, terpenes, aldehydes, and sulfur-containing compounds. Contributions that highlight novel analytical methodologies—such as GC–MS, LC–MS, NMR, spectroscopy, metabolomics, or chemometric modeling—are particularly encouraged. Studies exploring fermentation processes, aging mechanisms, oxidation reactions, and chemical indicators of quality, origin, or sustainability are also welcome. By integrating analytical chemistry, biochemistry, and sensory science, this Special Issue seeks to provide a comprehensive overview of the current landscape in wine research and to stimulate further developments in the molecular understanding of wine composition, authenticity, and sensory expression.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

To further understand redox mechanisms occurring in wine, caffeic acid (CAF, 150 mg/L) and/or glutathione (GSH, 150 mg/L) were added to a model wine solution, followed by ferric iron (2 mg/L Fe(III), added as 10 mg/L Fe(III) chloride hexahydrate), while monitoring the oxidation–reduction [...] Read more.
To further understand redox mechanisms occurring in wine, caffeic acid (CAF, 150 mg/L) and/or glutathione (GSH, 150 mg/L) were added to a model wine solution, followed by ferric iron (2 mg/L Fe(III), added as 10 mg/L Fe(III) chloride hexahydrate), while monitoring the oxidation–reduction potential (ORP, redox potential). Caffeic acid produced only modest ORP changes. In contrast, glutathione and caffeic acid + glutathione additions dropped the ORP from 243 mV and 238 mV, respectively, to the same post-addition value of 189 mV, suggesting that glutathione dictated the ORP, while caffeic acid showed no effect. The quinone of caffeic acid (assumed as changes in AU at 420 nm), was not detected, suggesting caffeic acid did not participate in oxidation reactions under wine conditions under superfluous amounts of dissolved oxygen (DO). After the addition of Fe(III), ORP increased to similar values across all treatments: 266 mV (FE), 269 mV (CAF), 284 mV (GSH), and 242 mV (CAF + GSH), suggesting that the Fe(II)/Fe(III) redox couple dominated the ORP electrode response. CAF + GSH produced the steepest ORP decline after the addition of Fe(III) chloride hexahydrate (β (slope of the ORP) = −0.7082), significantly steeper than FE (β = −0.3051; p = 0.0032) and GSH (β = −0.4643; p = 0.0496), suggesting synergistic radical quenching and metal redox cycling. Photo-Fenton-like reactions likely contributed to slight decreases in the ORP over time. In conclusion, glutathione strongly lowered the ORP, Fe(III) increased the ORP across treatments, and caffeic acid had minimal impact on the ORP under model wine conditions. Full article

Wine is a rich source of biologically active compounds, particularly polyphenols, which exhibit antioxidant and antiradical properties. The objective of this study was to optimize the vinification procedures of Polish wines from the hybrid white grape cv. ‘Johanniter’ and red grape cv. ‘Regent’, grown in the temperate climate of central Europe, by applying different skin maceration times: 4, 8, 12, 16, and 20 days. The wines were compared for their basic oenological characteristics and polyphenolic (UHPLC–MS) content as well as their antioxidant (FRAP test) and antiradical (DPPH test, ORAC-fl and EPR spectroscopy) capacities. Both wines demonstrated a substantial increase in their total phenolic content and antioxidant and antiradical capacities after a 4-day maceration; further treatment did not lead to considerable enrichment in bioactive compounds. Scavenging activities against nitroxyl radicals and DPPH were divergent for the tested wines and depended on the analytical method applied, which indicated distinct molecular mechanisms. In turn, the activity of peroxyl radical scavengers, antioxidant capacity, and the total content of phenolics were higher in all the red wine samples. The antioxidant and antiradical properties of the examined wines were comparable or even exceeded those determined for most wines produced in regions with a rich winemaking tradition. Full article
