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.

Vertical cordon training system enhances yield and delays ripening in cv. Maturana Blanca

The growing interest in minority grape varieties is due to their potential for adaptation to global warming and their oenological capabilities. However, the cultivation of these varieties has often been limited due to their low economic efficiency. One such example is Maturana Blanca, a recently recovered and authorized minority grape variety in the DOCa Rioja region, known for its remarkable oenological potential but low productivity. This study aimed to increase the yield of Maturana Blanca by implementing the vertical cordon training system, which allowed for a higher number of buds per plant and an increased cluster count per vine.

Ecophysiological characterisation of terroir effects on Vitis vinifera L. Chardonnay and pinot noir in south african cool climate regions

Terroir encompasses environmental (climate, geology, soil and topography), genetic (cultivar and clone) and human factors (oenological and viticultural practices). Climate change brings about shifts in the suitability of a region for the growth of specific grapevine cultivars. This study focused on climatic and fruit parameters (berry size, weight, pH, total acidity (TA) and phenolics) to characterise the terroir effect in Vitis vinifera L. cultivars Chardonnay and Pinot Noir vineyards in the Cape South Coast region (Walker Bay and Elgin).

Impact of climate on berry weight dynamics of a wide range of Vitis vinifera cultivars 

In order to study the impact of climate change on Bordeaux grape varieties and to assess the behavior of candidate grape varieties potentially better adapted to the new climatic conditions, an experimental vineyard composed of 52 grape varieties was planted in 2009 at the INRAE Bordeaux Aquitaine center[1]. Among the many parameters studied since 2012, berry weight for each variety was measured weekly from mid-veraison to maturity, with four independent replicates. The kinetics obtained allowed to study berry growth, a key parameter in grape composition and yield.

The use of plasma activated water in barrel disinfection: impact on oak wood composition

The use of barrels is a practice that improves the quality of wines. The porous structure of wood favors the accumulation of microorganisms that can deteriorate the quality of wines so that barrel cleaning and sanitizing treatments are essential. The burning of sulphur discs has been the most common practice in winemaking because ots biocide effect. Nevertheless, its effectiveness is still insufficient and it is harmful for human health.

Optimization of the acquisition of NIR spectrum in grape must and wine 

The characterization of chemical compounds related with quality of grape must and wine is relevant for the viticulture and enology fields. Analytical methods used for these analyses require expensive instrumentation as well as a long sample preparation processes and the use of chemical solvents. On the other hand, near-infrared (NIR) spectroscopy technique is a simple, fast and non-destructive method for the detection of chemical composition showing a fingerprint of the sample. It has been reported the potential of NIR spectroscopy to measure some enological parameters such as alcohol content, pH, organic acids, glycerol, reducing sugars and phenolic compounds.
