This study explores the impact of natural flower extracts from , , and to enhance the aroma of dealcoholized Chardonnay wine, addressing the sensory deficiencies commonly associated with dealcoholized wine beverages (DWBs). The investigation revealed a richer bouquet of aromatic compounds, particularly higher alcohols, esters, and terpenes, which significantly elevated the aromatic profile of treated wines without altering their physicochemical properties. Principal Component Analysis (PCA) showed distinct aroma profiles between control and flower extract-DWBs, with the latter exhibiting enhanced floral and fruity characteristics. Additionally, Partial Least Squares Regression (PLSR) showed a positive correlation between specific volatile classes especially terpenes and esters, sensory attributes of floral and fruity notes, highlighting the crucial role of these compounds in enhancing overall aroma. These findings not only present a promising opportunity to improve the appeal of DWBs, but also suggest a potential for broader applications in the beverage industry.

Seaweed extracts are promising plant biostimulants for viticulture, but their effects on white winegrape cultivars grown under cool climates remain fairly undocumented. Furthermore, information is limited on the biostimulant potential of some brown seaweed species like Ecklonia maxima. This study evaluated the impact of two commercial extracts (derived from Ascophyllum nodosum and Ecklonia maxima) on Vitis vinifera cv.

The quality of white wine is related to sensory attributes like color, odor and taste. This study focused mainly on taste attributes of white wines. The research hypothesis was to find out if taste-related attributes alone, determined by sensory experiment, could discriminate Chardonnay versus non-Chardonnay wines.

Smoke taint is a fault that can occur in wines made from smoke-affected grapes. Smoke taint research has largely focused on chemical and sensory analysis and mitigation strategies, with limited attention to underlying molecular responses. We performed RNA sequencing on berries from cultivars Shiraz and Chardonnay after controlled smoke exposure.

Lactobacillus species, naturally present in the microbiota of grapes and wine, are gaining increasing attention in the wine industry due to their significant influence on the chemical and sensory profiles of wine. This study investigates the impact of two lactic acid bacteria strains-Lactiplantibacillus plantarum ML Prime and the native Levilactobacillus brevis BCV-46-on the fermentation of Chardonnay wines. Laboratory-scale fermentations were carried out with the simultaneous inoculation of Saccharomyces cerevisiae and each lactic acid bacteria strain.

Current early oxidation detection methods include assessment by browning index, trained sensory panels, and quantification of byproducts such as quinones. The objective of this study was to assess the capability of the e-tongue, a fairly new instrument that has previously been used to detect wine faults caused by spoilage organisms, in detecting early oxidative changes in Chardonnay wine.
