Moderate wine consumption – part of a balanced diet or a health risk?

Abstract

Consumption of wine/alcoholic beverages remains a topic of great uncertainty and controversy worldwide.  The term “no safe level” dominates the media communication and policy ever since population studies in 2018 [1,2] were published, which denied the existence of a J-curve and suggested that ANY consumption of an alcoholic beverage is harmful to health. The scientific evidence accumulated during the past decades about the health benefits of moderate wine consumption, were questioned and drinking guidelines considered to be too loose. As a consequence, during the last few years, the upper limit of low-risk alcohol consumption has been progressively lowered in the national drinking guidelines. 

Although the authors of the Global Burden of Disease (GBD) study concluded in 2018 that it would be best for overall health to avoid drinking at all, the same GBD scientists in 2022, corrected their own previous data.  In their 2022 update [3] – different from the 2018 publication – the alcohol-related health risks in every country were considered. The results showed that the risks from the consumption of alcoholic beverages vary greatly depending on the disease, age and region. Based on these new results, a moderate consumption of wine/alcoholic beverages for individuals above 40 years of age can provide health benefits, such as a lower risk of cardiovascular diseases and diabetes. The influence of moderate wine/alcohol consumption on health was described by a J-shaped curve. Excessive drinking is always associated with an increased risk of death and various health risks.

What are the reasons for such contrary results and what is the practical significance of “global calculations” in both GBD studies?  What does it mean for the wine consumer? The latest scientific evidence of moderate wine consumption in the context a healthy lifestyle and diet will be discussed, as well as how the communication of the Wine in Moderation initiative builds on objective scientific facts.

Metabolomic profiling of botrytized grape berries: unravelling the dynamic chemical transformations during noble rot

Botrytis cinerea, a fungal pathogen commonly known as grey mold, which under specific climatic conditions can develop into a desirable form known as noble rot. In this process the fungus penetrates the grape skin, allowing water evaporation and concentration of sugars and flavors, while profoundly affects the metabolite composition of grapes, leading to the production of unique and desirable compounds in the resulting wines. The result is a unique and complex wine with a luscious sweetness, heightened aromatics, and a distinct character.

Volatilome in grapevine leaves is defined by the variety and modulated by mycorrhizal symbiosis

Volatile organic compounds (VOCs) constitute a diverse group of secondary metabolites key for the communication of plants with other organisms and for their adaptation to environmental and biotic stresses. The emission of these compounds through leaves is also affected by the interaction of plants with symbiotic microorganisms, arbuscular mycorrhizal fungi (AMF) among them [1]. Our objective was to know the concentration and profile of VOCs emitted by the leaves of two grapevine varieties (Tempranillo, T, and Cabernet Sauvignon, CS, grafted onto R110 rootstocks), inoculated or not with a consortium of five AMF (Rhizophagus irregularis, Funneliformis mosseae, Septoglomus deserticola, Claroideoglomus claroideum and C. etunicatum).

Performance of Selected Uruguayan Native Yeasts for Tannat Wine Production at Pilot Scale

The wine industry is increasing the demand for indigenous yeasts adapted to the terroir to produce unique wines that reflect the distinctive characteristics of each region. In our group, we have identified and characterized 60 native yeast strains isolated from a vineyard in Maldonado-Uruguay, in which three strains stood out: Saccharomyces cerevisiae T193FS, Saturnispora diversa T191FS, and Starmerella bacillaris T193MS. Their oenological potential was evaluated at a semi-pilot scale in Tannat must vinification in the wine cellar to have a more precise and representative evaluation of the final product.

Effect of ultraviolet B radiation on pathogenic molds of grapes

The fungicidal effect of UV-C radiation (100-280 nm wavelength) is well known, but its applicability for the control of pathogenic molds of grapes is conditioned by its effect on the host and by the risks inherent in its handling[1].
As an alternative, the effect in vitro of UV-B radiation (280-315 nm) on the main pathogenic molds of grapes has been studied: Botrytis cinerea, Aspergillus niger, Penicillium expansum and Rhizopus stolonifer.

Assessing the Effectiveness of Electrodialysis in Controlling Brettanomyces Growth in Wine

Brettanomyces yeast can negatively impact the quality and stability of wines, posing a significant challenge to winemakers. [1] This study aims to develop novel management practices to limit Brettanomyces impact on wines by evaluating the effectiveness of electrodialysis (ED) technology in removing magnesium (Mg2+) from wine to prevent the development of Brettanomyces yeast. The ED technique utilizes charged membranes to extract ions from the wine, and it is considered an alternative to cold stabilization that requires less energy. [2]
