Analysis and composition of grapes, wines, wine spirits

Analysis and composition of grapes, wines, wine spirits Winemaking processes and oenological practices

Chemical composition of press and free-run wines from three vintages and Bordeaux grape varieties. A comprehensive analysis

Press wines play a crucial role in red winemaking, representing up to 15% of the final blend [1]. Optimizing their value is essential both economically and for maintaining wine identity, especially given evolving climatic and societal challenges. However, little recent research exists on their composition.

Circular economy strategies to reintegrate grape pomace from cv. Lagrein into the food chain

The project REALISM (regionality and circular economy in food products to counteract the Metabolic Syndrome (M.S.)) was initiated to develop antioxidant-rich food products with the ability to reduce the risk of developing the M.S.

Classification of “Valpolicella Superiore” wines in relation to aromatic composition: influence of geographical origin, vintage and aging

The Valpolicella appellation, mainly known for Amarone and Ripasso, is experiencing growing interest in Valpolicella Superiore (VS), a lighter red wine aligning with consumer demand. However, anecdotal evidence suggests different stylistic interpretations of VS, potentially causing consumer confusion.

Colloidal color stabilization in wine: A comparative study of Saccharomyces and non-Saccharomyces mannoproteins

Structure-function relationships between the polysaccharide part of S. cerevisiae Mannoprotein Pools (MPs) and their potential to interact with anthocyanins and Protein-Tannins aggregates was previously assessed [1,2].

Colour, phenolic, and sensory characteristics of commercial monovarietal white wines produced with maceration

White wines produced with skin and seed contact are of great interest in the wine sector. Maceration, whether performed prior to or concurrently with alcoholic fermentation, or even extended beyond its completion, significantly impacts the chromatic, mouthfeel, and aroma characteristics of these wines.

Comparison of the aroma profile in total and partial dealcoholisation of white and red wines by reverse osmosis

The increasing demand for low-alcohol and non-alcoholic wines has led to the development of advanced dealcoholisation techniques aimed at preserving wine quality while reducing ethanol content. Reverse osmosis is one of the most widely used membrane-based processes for the selective removal of ethanol [1].

Comparison of the principal production methods for alcohol-free wine based on analytical parameters

Production, demand, and brand awareness of dealcoholized wine (<0.5% v/v) is steadily increasing worldwide. However, there have been few studies to date investigating and comparing the different physical processes for dealcoholizing wine.

Composition and biological potential of grape and wine phenolic compounds

Polyphenols are common in human diets, primarily in plant-derived food and beverages. They influence multiple sensory properties such as aroma, flavour, colour, and taste, such as astringency and bitterness [1]. The major phenolic compounds in grapes and wines are anthocyanins and tannins (proanthocyanidins or condensed tannins).

Comprehensive lipid profiling of grape musts: impact of static settling

Lipids are crucial in alcoholic fermentation, influencing yeast metabolism by providing nutrients and modulating membrane composition [1]. They also serve as precursors to aromatic compounds shaping wine sensory profiles [2].

Convergence and divergence in chemical and sensory profiles of disease-resistant and Vitis vinifera white wines from South Tyrol: addressing strategies for market adoption

This study investigates the chemical and sensory profiles of white wines produced from disease-resistant hybrid grape cultivars (DRHGCs) compared to traditional Vitis vinifera L. cultivars in South Tyrol, Italy.

Analysis and composition of grapes, wines, wine spirits Chemical and biochemical reactions, including grape and wine microorganism’s impact

Crafting wine’s signature: exploring volatile compounds from terroir to aging

The unique characteristics of terroir play a fundamental role in shaping the identity and quality of wines, influencing the aromatic complexity of young wines and their long-term aging potential. The volatile compounds responsible for these aromas are crucial to identifying and appreciating a given wine.

Cross analytical and sensory differentiation of monovarietal white wines from four autochthonous grape varieties: focus on macromolecules

White wines contain macromolecules such as proteins, phenolic compounds and polysaccharides. On a sensory
level, these compounds contribute to the 'mouthfeel' that differentiates the white wines worldwide [1].

Development of a new lab-scale carbonation method for applications to sparkling wines

Carbon dioxide (CO2) is the gaseous species responsible for the sparkle in all sparkling wines, influencing their
visual appearance, aromas and mouthfeel.

Development of an analytical method for the quantification of compounds responsible for the green character of wines: influence of ripeness on their levels

Red wines can sometimes exhibit undesirable green, herbaceous, and vegetative aromas, negatively impacting their sensory profile and consumer acceptance.

Development of novel drought-tolerant grape cultivars from Monastrell: enhancing anthocyanin and flavonol content under elevated temperatures

The ongoing challenge of climate change is driving the need for novel oenological approaches aimed at finding effective environmental solutions.
