Chitosan as an alternative to SO2 in winemaking: A preliminary trial
Sulphur dioxide is the most widely used additive in winemaking because of its antimicrobial and antioxidant properties.
Role of winemaking strategy and storage temperature in the sensory profile of a single-varietal Eva white wine (2025 vintage)
The sensory characteristics of wine strongly influence consumer acceptance and market value. In young white wines, maintaining these characteristics over time is especially important and depends on both winemaking technology and storage temperature.
Physicochemical characterisation of white, rosé and red wine lees
Wine lees are of considerable interest because their solid fraction contains microorganisms, tartaric acid and organic residues, and may provide compounds with technological applications in the food and wine industries.
Sensory characterisation of dealcoholised wines
Dealcoholised wines have attracted increasing interest from both producers and consumers because they respond to demand for healthier beverages with lower alcohol content while aiming to preserve the sensory experience of wine.
Perceived quality and sensory profile of commercial 0.0 % red wines
The market for low- and no-alcohol beverages is growing rapidly because of health and well-being concerns, generational change, road-safety regulations, and other factors.
Evaluation of the volatile composition and sensory profile of an alcoholic beverage made from grapes and service-tree fruit
Market saturation, changing consumer preferences and demand for differentiated products have encouraged the wine sector to explore innovative fermented beverages. Service-tree fruit (Sorbus domestica) is of interest because of its traditional use, bioactive compounds, and aroma precursors.
Postharvest UV-B radiation as a sustainable strategy for controlling Botrytis cinerea and associated microbiota in wine grapes
Damaged grapes and grey mould are major causes of reduced oenological quality, with Botrytis cinerea being particularly relevant because of its sanitary and technological impact.
Composition of irrigated red and white Grenache grapes under different soil-management systems in semi-arid Mediterranean conditions (2025 vintage)
Conventional vineyard tillage and herbicide use can negatively affect soil quality and ecosystems, particularly under Mediterranean climate-change conditions.
Preliminary clonal characterisation of Malvasía Volcánica using SSR markers in traditional Lanzarote vineyards
Malvasía Volcánica is one of Lanzarote’s most representative white grape cultivars and is grown under demanding semi-arid conditions characterised by high solar radiation, volcanic soils and strong trade winds.
Grapevine genetic identity and diversity on La Palma: contributions to the Canary Islands centre of viticultural biodiversity
The Canary Islands are recognised as an important centre of grapevine biodiversity because of their geographic isolation, long viticultural history, and absence of phylloxera.
Multi-platform rapid quantification of wine microorganisms: smartphone, microplate reader, real-time qLAMP and PMA-qLAMP approaches
The rapid and accurate quantification of wine microorganisms is essential for quality control and spoilage prevention.
Evolution of colour and phenolic composition in dealcoholized white, rosé, and red wines during bottle storage
The growing demand for no- and low-alcohol (NoLo) wines has augmented research into post-fermentation dealcoholization technologies and their effects on wine quality.
Effects of grapevine leafroll associated virus 2 infection on leaf net photosynthesis, yield and berry quality in Vitis vinifera cv. Malbec
Grapevine leafroll associated virus 2 (GLRaV-2) is one of the most common damaging viral diseases in vines, causing significant reductions in photosynthesis, yield and grape quality. In this study, we tested the hypothesis that the leaf net photosynthesis and the transport of sugars to the berries is progressively reduced along the season in vines infected with GLRaV-2, and consequently, the yield (kg per plant) and total soluble solids (TSS) at the berry harvest-ripe stage are lower than non-infected vines.
Syrah wine from São Paulo’s high lands – Brazil, chemical and sensorial characterization, with a extemporaneous production cycle
Brazil has a wide territorial area, with much differentiated edaphoclimatic characteristics. It makes this study important to characterize new regions with viticulture potential.
Influence of genotype and water availability on respiratory costs and plant carbon balance in grapevines (Vitis vinifera L.)
Due to the important contribution of agriculture to the global carbon dioxide (CO2) balance, new techniques are currently being developed to accurately estimate the carbon balance of different crops. Field studies to date in grapevines have been based on carbon allocation and biomass accumulation dynamics.
Phenological behavior and evolution of maturation of grapes of juice preparation
The ripening level of the grape is one of the most important factors in the quality of its derivatives, because of the complex phenomena inherently related to the varieties and environmental conditions. The objective of the present study was to monitor the phenological development of the Chardonnay variety and to evaluate the influence of the different ripening points on the production of juices.
Measurement of quality potential: insights into planting choices
Within the current context of climate change, the choice of variety and rootstock for each specific pedo-climatite becomes critical.
Sensory profile: impact of grape vine yield and irrigation strategies in Vitis vinifera Cabernet-Sauvignon
The yield and irrigation strategies have an effect in maturity and chemical profile of grape, also an effect on the sensorial profile of the wine.
Impact of the source sink ratio on vegetative growth, yield, and reserves accumulation on a minimal pruning vineyard
Vines under minimal pruning reach a balance between vegetative growth and yield.
Influence of trellis system and shoot density of a vineyard in light interception and productivity
Different types of trellis systems determine different canopy spatial distributions, allowing greater or lesser shoot density in order to maximize the efficiency of light interception and productivity.
