Analysis of temporal variability of cv. Tempranillo phenology within Ribera del Duero Do (Spain) and relationships with climatic characteristics

Abstract

The Ribera del Duero Designation of Origin (DO) has acquired great recognition during the last decades, being considered one of the highest quality wine producing regions in the world. This DO has grown from 6,460 ha of vineyards officially registered in 1985 to approximately 21,500 ha in 2013. The total grape production stands at around 90 million kg, with an average yield that approaches nearly 4,500 kg/ha. Most vineyards are cultivated under rainfed conditions. For that reason climate variability, with higher temperatures and higher water demands, may affect grape development and production. The aim of this work was to analyze the influence of the climatic characteristics on phenology within the DO. Twenty plots planted with Tempranillo (the main variety cultivated in the area) were analyzed from 2004 to 2012. The representativeness of those years was analyzed by comparing their characteristics with a longer series recorded from 1980 to 2012. The relationship between phenology and the different variables were confirmed with a multivariable analysis. While the dates during the time period showed high variability, on average, bud break was April 28th; bloom June 16th and veraison August 12th. Differences of up to 21 days in the dates were observed between years, with the earliest dates observed in dry years (2005, 2006 and to a lesser degree in 2009). On the other hand, later dates occurred in the wettest year of the period (2008). High correlations were found between veraison and temperature variables as well as with precipitation-evapotranspiration recorded during the bloom-veraison period. These effects tended to be higher in in the central part of the DO.

Paysages viticoles et terroir dans l’OAC Ribeira Sacra (Galice, NO de l’Espagne)

The concept of Appellation d’Origine Contrôlée (AOC) is based on the existence of a link between the characteristics of the terroir and the quality and typicality of the production (DELAS, 2000). If for a long time, this link only appeared as the fruit of empiricism, the research undertaken recently has made it possible to scientifically establish the complex relationships between the functioning of natural environments and the ability to produce quality.

The role of tomato juice serum in malolactic fermentation in wine

Introduction: Malolactic fermentation (MLF) is a common process in winemaking to reduce wine acidity, maintain microbial stability and modify wine aroma. However, successful MLF is often hampered by their sluggish or stuck activity of malolactic bacteria (MLB) which may be caused by nutrient deficiency, especially when MLB are inoculated after alcoholic fermentation (Alexandre et al., 2004; Lerm et al., 2010). Identification and characterization of essential nutrients and growth factors for MLB allows for production of highly efficient nutrient supplements for MLF.

Polyphenolic profile and dietary fiber content of skins and seeds from unfermented and fermented grape pomace

The valorization of winemaking byproducts is subordinated to the knowledge of their chemical characteristics. This work concerned the determination of the polyphenolic profile and the dietary fiber content of skins and seeds from unfermented and fermented pomace of different cultivars (Moscato bianco, Cortese, Arneis, Pinot Noir, Barbera, Grignolino, Nebbiolo), sampled from some wineries in the Piedmont area (Italy) during the 2020 harvest.

Application of a low-cost device VIS-NIRs-based for polyphenol monitoring during the vinification process

In red wine production, phenolic maturity is becoming increasingly important. Anthocyanins, flavonoids and total polyphenols content and availability significantly influence the harvest time of wine grapes while, during vinification process, their extraction strongly affects wine body, color and texture

Social and environmental impacts of the adoption of a variety of table grape in the region of vale do São Francisco – Brazil

This study explores and analyzes the socio-environmental implications associated with the cultivation of the “brs-vitoria” table grape variety. Focusing on its adoption by farmers in the vale do submédio São Francisco region in Brazil, this study delves into the diverse impacts and changes brought about since its introduction, encompassing both the social and environmental dimensions of agricultural practices in the area. Embrapa, brazil’s federal agricultural research institution, encompasses a network of 43 thematic research centers spread across the nation.
