Identification and quantification of furaneol-β-glucoside by LC-MS/MS in berries and wine during ripening and winemaking
Furaneol® (2,5-dimethyl-4-hydroxy-3(2H)-furanone) is a key wine aroma compound reminiscent of strawberry and caramel notes and, together with other furanones and lactones, contribute to overwhelming dried fruit aromas.
From grapes to data: rapid must characterization using benchtop NMR spectroscopy
Fast and reliable compositional analysis of grape must is essential for process control and quality assurance in winemaking.
Multi-isotopic dilution QQQ-ICP/MS for high geographical discrimination of origin and quality assessment in wine: developing a world database and demonstration of its potential of applications
Trace elements in wine are primarily markers of the soil in which the vine grew (e.g. Rb, Sr, Ba, …), other elements are markers of agricultural practices (e.g. Cu, B, …) and others are markers of anthropogenic contaminations (e.g. Pb, As, …).
Decoding antioxidant mechanisms in specific inactivated yeast
Inactivated yeasts, like many other enological biotechnologies, are routinely characterized by producers to assess their functional performance.
Understanding the occurrence and evolution of thiophenols in wine
Redacted.
Expanding white wine peptide coverage through an integrated LC-MS workflow
Peptides are attracting growing interest as contributors to the main qualitative characteristics of wine, including oxidative stability, aromatic development, and mouthfeel impact (1,2).
Optimization of sorbent sheet geometry for high-throughput targeted odorant analysis
Targeted trace level (< mg/kg) quantitative analysis of volatiles in wines, grape, and other matrices is time consuming and expensive.
Peptide profiling and antioxidant capacity of white grape juice using LC-MS approach
The oxidative stability of white wine is governed by a complex network of native metabolites collectively described as the wine antioxidant metabolome1.
Influence of berry skin cuticular wax on smoke-derived volatile phenol uptake in grapes
Wildfire smoke exposure is known to alter grape composition and cause “smoke taint” in the resulting wines, causing significant economic losses (USD 3.7B in the US in 2020).
Phenolic compounds evolution of still dry Chenin blanc wines during oak barrel aging on lees
Oak barrel aging is a traditional practice used in winemaking to produce high quality white wines. The impact of this practice over the evolution of volatile compounds in white wines is well documented.
The taste of white wines : is there a specific Chardonnay taste?
The quality of white wine is closely linked to its sensory profile, including colour, odour, and taste.
AF4 – UHPLC: two-dimensional separation of macromolecules in monovarietal white wines from South-Western France
The French south-west region is unique in having over 300 grape varieties for wine production, 120 of which being indigenous.
Bridging the gap: integrating advanced data science with untargeted grape metabolomics
The unbiased characterization of grape and wine matrices through metabolomics generates vast and high-dimensional datasets which potentially represent strong foundations to expand our understanding of complex chemical and biological interactions.
How closure oxygen permeability impacts tannin evolution in long-term aged red wines: breaking analytical barriers using UHPLC–UHRMS metabolomics and MS/MS-based molecular networking
The significant role played by condensed tannins (CTs) in oenology has encouraged extensive research on these compounds.
Redox-dependent metabolomic signatures of red wine aging
Oxygen is a central factor in wine evolution, driving a network of redox-mediated chemical and biochemical processes that shape wine quality, stability, and sensory perception.
Exploring the relationship between wine chemical composition and its permissiveness to Brettanomyces bruxellensis via untargeted metabolomics
Brettanomyces bruxellensis remains a major challenge for the wine industry. Its development is typically revealed by “horse sweat” or “burnt plastic” off flavours in red wines, aromas that are not aligned with today’s consumer expectations.
Do wine lees derived biomolecule mixtures lead to enhancing the grapevine innate immunity? A metabolomic study on Vitis vinifera leaves
Downy mildew (Plasmopara viticola) is one of the most devastating diseases of Vitis vinifera.
Comprehensive profiling of glycosidic aroma precursors in grapes via semi-preparative LC fractionation, GC-MS, and UHPLC-MS analysis
Glycosidically bound aroma compounds are the most abundant non-volatile precursors and play a key role in wine aroma formation [1].
Untargeted GC-MS metabolomics to evaluate how red grape varieties and synthetic must impact volatile profiles of grape-associated fungi
Mycobiota from vine-to-wine is highly diverse and can affect grape quality at harvest as well as wine sensory properties, sometimes leading to off-flavors.
Spectrofluorometric fingerprinting to track the evolution of red wine and model the relationship with compositional aspects
Red wine contains an abundance of phenolic constituents that crucially contribute to sensory appeal.
