Article Abstract
Aroma plays an important role in food quality, and knowledge of volatile composition is essential to support technological choices during industrial transformation processes. In this study, an innovative GC-MS/MS method useful for fast analysis of the broad aroma profile of oenological products was developed. Fifty volatile compounds of oenological interest belonging to the main chemical classes (acetates, acids, alcohols, aldehydes, esters, ketones, phenols, terpenes, and thiols) were identified and quantified in a single chromatographic run taking only 15 minutes. The high sensitivity of the mass spectrometer, combined with accurate fast chromatography performed with a suitable capillary column, allowed us to avoid further concentration steps after solid phase extraction. Validation of the method was performed in relation to the limit of detection, limit of quantification, linearity range, repeatability, reproducibility, and recovery. Once validated, the method was successfully tested on commercial oenological samples, demonstrating its applicability to fast routine multiaroma analysis.

Zygosaccharomyces bailii is a non-conventional wine yeast, traditionally recognized for its spoilage potential in food and beverages. However, strain-level variability within this species presents an opportunity to identify efficient, non-spoilage strains with promising applications as wine starter cultures. The aim of this study was to investigate the interaction between indigenous strains of Saccharomyces cerevisiae and Z.

Climate change is expected to significantly reshape viticulture across traditional wine regions, including the Douro winemaking region (DWR) in northern Portugal. This study evaluates projected impacts of climate change on key viticultural parameters, such as grapevine yield, phenology, and potential alcohol content, using an ensemble of high-resolution downscaled climate simulations for the recent-past (1986 to 2015) and for two emission scenarios: SSP1-2.6 (low-emissions pathway) and SSP5-8.

This study evaluates the impact of two non- yeasts, and , on the oenological and sensory characteristics of Pedro Ximénez (PX) white wines produced in warm regions of southern Spain. PX wines are particularly affected by climate change, often exhibiting low acidity and limited aromatic complexity. Fermentations were performed using pure and sequential cultures of these yeasts and compared to a control inoculated with .

The process of selecting indigenous Saccharomyces cerevisiae strains as a starter culture for specific fermentation has several requisites, including the assessment of distinct parameters based on desirable and traditional oenological criteria. In most wineries, commercial Saccharomyces cerevisiae strains are used for wine fermentation. However, it is rare to find indigenous cerevisiae strains used in wine production, even though these isolates are better adapted to specific regions and are often preferred for producing local fruit wines.

Introduction: This study investigates the antimicrobial activity of chitosan against , a wine spoilage yeast responsible for producing volatile phenols that lead to undesirable sensory defects commonly referred to as "Brett" character. The most widely used antimicrobial compound in oenology is sulphur dioxide (SO), due to its broad spectrum of action, but growing consumer demand for reduced chemical additives and evidence of spp. resistance to it, have encouraged different alternative strategies.
