Moderate wine consumption as part of a Mediterranean diet and lifestyle under debate

Moderate wine consumption - with the meals - represents one of the beneficial components of the traditional mediterranean diet (med diet) and a positive item in the med diet score [1,2, 3]. The med diet is considered one of the best diets in the world and the world health organisation (who) identified this eating pattern as an effective strategy to prevent non-communicable diseases (ncd), since it is associated with lower disease occurrence and all-cause mortality [4] . Numerous well-conducted epidemiological studies have also reported that light-to-moderate intake of wine/alcoholic beverages is not only related to a reduced risk of cardiovascular disease, but also to all-cause mortality.

Mousy off-flavor detection: a rapid LCMS/MS method

These days, consumers are interested in food products linked to the environment and the concept of naturalness. They prefer "free" products, such as those with no pesticide residues or no added sulfur dioxide (so2) in wines. In fact, so2 is the most widely used preservative in winemaking, as it has multiple properties at low cost: it is antioxidant, antioxidasic and antimicrobial.

Multi-mineral wine profiling and Artificial Intelligence: Implementing the signatures of each wine to train algorithms to meet the new challenges facing the wine industry

Multi-mineral wine profiling and artificial intelligence: implementing the signatures of each wine to train algorithms to meet the new challenges facing the wine industry. Although their quantity is minimal, minerals are essential elements in the composition of every wine. Their presence is the result of complex interactions between factors such as soil, vines, climate, topography, and viticultural practices, all influenced by the terroir. Each stage of the winemaking process also contributes to shaping the unique mineral and taste profile of each wine, giving each cuvée its distinctive characteristics.

Multi-trait selection in ancient grapevine varieties

The selection of ancient grapevine varieties aims to achieve genetic gains in several important traits that can make the variety more interesting for the objectives of the producers. Traditionally, yield and quality traits of the must have been considered for selection, but many others can be taken into account. Linear mixed models are fitted to the data to predict the empirical best linear unbiased predictors (EBLUPs) of genotypic effects for each evaluated trait, which will be the basis for selection.

Natural glycolipids for the control of spoilage organisms in red wine

A natural glycolipid mixture obtained from the edible mushroom dacryopinax spathularia ("glycolipids") is known to be an effective and approved antimicrobial treatment in non-alcoholic beverages at concentrations ranging from 5 – 100 mg/l. It has found a place alongside DMDC for the provision of microbial stability in soft drinks. These properties make the natural and sustainably produced glycolipids a promising candidate for the supplementation or replacement of SO2 in different winemaking processes.

NAVIC–20 years of a lean management model for wine business R&D

Considering That Innovation Supports A Company’s Competitive Advantage And Drive Higher Profits (Dogru A. & Peyrette J., 2022), A Key Challenge Of Wine Companies Is Getting Practitioners To Understand That Innovation-Related Wine Research Increases The Likelihood Of Competitive Advantage, Bringing Financial Success. A Continued And Enhanced Investment In Research Is, Thus, A Prerequisite For Commercial Success In Today’s Globalized And Competitive Wine Industry (Høj P., Pretorius I.S., & Day R., 2003).

New highlights of polyphenols from red wine to counteract ocular degenerative diseases

More recently, studies have shown that polyphenols could also prevent or improve vision in patients with ocular diseases and especially age-related macular degeneration (AMD) which is an eye disease characterized by damage to the central part of the retina, the macula, and that affects millions of people worldwide. Despite therapeutic advances thanks to the use of anti-vascular endothelial growth factor (VEGF), many resistance mechanisms have been found to accentuate the visual deficit.

New markers for monitoring “fresh mushroom aroma” in wine: A dual approach using microbiological and chemical tools from the vineyard to winery–A synthesis of recent research advances

The 'fresh mushroom off-flavour' has been recognized by the wine industry as an emerging defect since the 2000s. For many years, this off-flavour was not specifically characterized and rather grouped under 'earthy' and 'musty' taints. However, it has become increasingly problematic due to its rising prevalence. In some vineyards, incidents of this off-flavour now occur as frequently as once every five years. This trend may be associated with climatic changes affecting regions that are more prone to warm and wet seasons.

New oenological technology for adaptation to climate change: reduction of alcohol content during wine fermentation through stripping, with fermentative CO2

The capture and valorization of fermentative CO2 have been developed for several years by the company w platform for internal uses, notably in the cellars: inerting, cooling, reduction of water consumption, extraction, with aroma valorization. In a context of climatic warming during the vegetative cycle, grapes are currently harvested with a significant sugar concentration, a phenomenon that is expected to intensify in the coming decades. The high alcohol content of the resulting wines goes against the demand of customers who are seeking high-quality wines with less alcohol.
