Vegetative propagation of Vitis vinifera cultivars over hundreds of years has led to the accumulation of a large number of somatic variants of the same grapevine variety. These variants are now considered a working tool to cope with changing environmental conditions as a result of, among others, global warming. In this work, three somatic variants of the major grapevine variety of the South West (SW) of Andalusia (Spain), Palomino Fino, have been genetically and morphologically characterized, as well as their grape musts from two different vintages.
This post is about a study aimed to assess the long-term soil erosion rates in Tierra de Barros, Extremadura (south-west Spain) applying the Improved Stock Unearthing Method (ISUM). The method is a low-cost and easy-to-apply method. In the future, authors claim that ISUM can be applied in countries of Asia, Africa or South America.
‘Glera’ and ‘Ribolla Gialla’ are the most economically relevant local grapevine cultivars of Friuli Venezia Giulia region (north-eastern Italy). ‘Glera’ is used to produce the world-renowned Prosecco wine. Combining molecular markers and historical references was a high-performance strategy for retracing and adjusting the history of cultivars.
Governo all’uso toscano (GUT) is a traditional winemaking practice where withered grapes are added to a freshly fermented wine. This results in a second alcoholic fermentation and a distinctive wine, in which there is renewed interest. Traditional winemaking practices could be a rich source of inspiration for modern oenology. Although these methods were developed in a specific context, they can greatly contribute to face modern oenological challenges. Finally, their study could help to preserve wine heritage and culture.
The geolocation of vine status in the vineyard after smoke of bushfire exposure, represents a pivotal economic and decision support tool to assist winegrowers and reduce time and cost of recovering practices. Unmanned Aerial Vehicle (UAV) adoption may be used to integrate cost analysis to aid growers and/or insurance adjusters to address quantification of damage and compensation for crop loss, or to integrate machine learning model to map contaminated area of vineyards also including berry quality traits by smoke.
Public policies should encourage vine growers to invest in producing high-quality local variety grapes as a diﬀerentiating character, as well as to develop agronomic practices that are environmentally and socially sustainable, by the grapes more adjusted to their real quality and production costs.
This post reports some initiatives from wine sector during this pandemic situation. A study on the behavior and attitudes of European wine consumers from European Association of Wine Economists. A solidarity action aiming to distribute disinfectant gel produced from wine spirit carried out from The Association of Port Wine Companies. Science & Wine propose the creation of a working group to prepare 2020 grape harvest.
This post reports the results of a research aimed to analyse the potential effect of climate change on phenology and berry composition of the variety Tempranillo cultivated in areas of the Rioja DOCa (Spain) with different climatic characteristics.
Screening grapes by size prior to winemaking could be a good tool for winemaking grape’s potential, but berry size per se could not be used as criteria for winemaking grape’s potential if grapes came from different origins, since skin’s thickness and seed’s proportion could not be neglected.
This post is a brief summary about a study aimed to develop an effective assay for the genetic traceability of ‘Nebbiolo’mono-varietal musts and wines. In particular, three main tasks were focused: identification of Nebbiolo’-specific SNPs starting from available databases and genotypes analysed by Vitis18kSNP array, optimization of DNA extraction protocols from must and wine, development of TaqMan® SNP assays for varietal authentication in ‘Nebbiolo’ musts and wines.
