Suitability of Vitis vinifera cv. Carignan versus cv. Tempranillo, in Rioja DOC (Spain), under different weather conditions and projected climate change scenarios

There is growing concern about the effects that a climate change may have on grape production and quality. This has led to studies carried out in different wine-growing areas of the world in which a trend of advance of phenology and harvest has been seen.  However, the degree of change may not be the same in all areas and for all varieties. Given the projected climate change scenarios that involve changes in temperatures and in precipitation, it is necessary to deepen the knowledge of the response of different varieties to these changes and identify those varieties that may be more resilient, in addition to adopting other measures that can help mitigate the effects of warming.

3rd World Science & Wine: Sustainability of wine production and food systems in the Mediterranean region

As promised, we will maintain the organization of the World Congress every two years. The 3rd World Science & Wine Congress will be from 14 to 16 June 2023 in Vila Nova De Gaia and the Douro region. The topic for this scientific meeting here will be “Sustainability of wine production and food systems in the Mediterranean region”.

Interest of polyphenols in the prevention of age-related diseases and in regenerative medicine

7-ketocholesterol and 7β-hydroxycholesterol are two oxysterols mainly formed by the autoxidation of cholesterol. These two molecules are interconvertible via specific enzymes. These two oxysterols are often observed at increased amounts in biological fluids as well as tissues and organs affected during age-related diseases and in diseases of civilization such as cardiovascular, neurodegenerative, and ocular diseases as well as type 2 diabetes and metabolic syndrome. Many nutrients present in significant amounts in the Mediterranean diet, especially tocopherols, fatty acids, and polyphenols, have shown cytoprotective activities as well as several Mediterranean oils (argan and olive oils, milk thistle seed oil, and pistacia lentiscus seed oil). Consequently, a nutraceutical approach, rich in nutrients present in the Mediterranean diet, could thus make it possible to counteract certain age-related and civilization diseases associated with increased levels of 7-ketocholesterol and 7β-hydroxycholesterol.

Vineyard management influences grape-borne fungal community and the aroma profile of wines: the case study of Montepulciano d’Abruzzo

This post summarizes the results of a study aimed to investigate the effect of farming practices on the diversity of grape fungal community of Vitis vinifera L. cultivar Montepulciano and the microbial metabolic activity. The obtained results revealed that farming practices shape the fungal community influencing wine traits linking the wine with the viti-vinicultural area of origin.

The Effects of Grape Polysaccharides Extracted from Grape By-Products on the Chemical Composition and Sensory Characteristics of White Wines

There is an increasing interest in the valorization of wine waste by-products. Grape pomace/marc can be an important source of polyphenols but also of polysaccharides (PSs). Therefore, the aim of this work was to extract PSs from grape pomace and musts and incorporate them into wines to improve their quality and valorize these residues. This is the first study that shows the effects of grape polysaccharides on the chemical composition and sensory characteristics of white wines. Considering the obtained results, the grape pomace and surplus of musts can be considered valuable sources to obtain polysaccharide-rich products, opening a new opportunity to take advantage of by-products from the wine industry

Festa do Tomate Coração de Boi do Douro

O Tomate Coração de Boi, que embeleza as hortas durienses e transmontanas durante o mês de agosto, é um fruto carnudo e sumarento muito apreciado por todos. Dada a sua importância para a região, desde 2016 que se organiza um evento festivo que visa promover este fruto, que encontra no Douro e em Trás-os Montes, ótimas condições para o seu amadurecimento.
The Tomate Coração de Boi, which beautifies the Douro and Trás-os-Montes vegetable gardens during August, is a fleshy and juicy fruit much appreciated by everyone. Given its importance to the region, since 2016 a festive event has been organized to promote this fruit, which is found in the Douro region and Trás-os Montes, with excellent conditions for its ripening.

Influence of Mediterranean Diet on Human Gut Microbiota

Gut microbiota changes correlate with health status. Literature data on gut microbiota show that all dietary changes can induce the alteration of gut microbiota composition. Mediterranean diet (MD) is associated with a reduction of all-cause mortality and in this review, Giuseppe Merra and collaborators analyzed its interactions with human microbiota. In particular, they explored the modulation of the human microbiota, in response to MD adherence, focusing the attention on polyphenols, polyunsaturated fatty acids (PUFA)ω-3 and fiber. Evidences suggest that MD is able to modulate the gut microbiota, increasing its diversity. In fact, a Mediterranean-type dietary pattern is associated with specific gut microbiota characteristics. The available evidence, suggests that gut microbiota of subjects that follow a MD is significantly different from subjects that follow a Western diet model.

False positive effect of sulfur sources used in growing and processing of vine (Vitis Vinifera L.) leaves on the results of dithiocarbamate analysis based on carbon disulfide measurement

Vine leaves, which are produced fresh, brined or fermented from the leaves of Vitis Vinifera in Türkiye are an important food. Sulfur is used as a pesticide and sulfur compounds can be used as additives during the growing and processing of the vine leaves. These sulfur sources cause positive results on carbon disulfide (CS2) measurements by GC-MS. Therefore, the main objective of the present study was to investigate the effects of residues of sulfur or sulfur compounds on dithiocarbamate analysis methods based on CS2 measurement.

Olive oil and exercise: sharing the same path to better health?

An olive oil (OO) rich diet or high-intensity interval training (HIIT) independently improve markers of health and energy metabolism, but it is unknown if combining OO and HIIT synergize to improve these markers. This study characterized the isolated and combined impact of OO and HIIT on markers of health and energy metabolism in various tissues in C57BL/6J female mice. The results highlight the pleiotropic effects of OO and HIIT, although their combination does not synergize to further improve most markers of health and energy metabolism.
