Clonal selection of Aragonez variety (syn. Tinta Roriz, Tempranillo) in the Douro wine region focused on quality improvement
Two field trials with 30 genotypes of the grapevine variety Aragonez (Portuguese official list code PRT52603, syn. Tinta Roriz, Tempranillo), coming from a first selection cycle, were established in 2012 in the Douro Wine Region (DWR), North Portugal: one in a steep slope area located at 194 m altitude and the other in a flat area at 471 m altitude.
With the context of global warming, are innovative varieties appropriates for PGI wines with typicality assessment?
With the context of global warming, which is causing earlier phenological dates for vines and changes in the quality of wines and with the regulatory context which lead to low phytosanitary treatment, understand how vines are liable to react to future regulation and climate evolution is important. But producers and consumers are not ready to accept rapid changes in the typicality of the products even if they are very attentive to wines quality.
Sustainable viticulture from theory to practice: first step
A definition of the term “Sustainability” few specifications (technique, economic, environmental, social, existential, ethical, global, meta-ethical) able to explain several aspects for which a viticulture can be considered sustainable. Viticulture is involved by all these implications over the technologies utilized along all the stages of the production and marketing chain. Intensification of cultivation, strategy of territory valorization, land use, mechanization, genetic improvement and labor exploitation are examined.
Proposition of a charter of sustainable viticulture following a survey inside the GiESCO
After a reminding of definitions of integrated, organic and biodynamic Viticultures, and following an internal survey in the GiESCO, a proposition of elements of a charter of sustainable Viticulture is made at the international level with attention to every interested stakeholder.
Basis eco-winetourism: from landscape to biodiversity of the terroir
The œnotourism takes a share growing in the valorization of the wine territories. It is also a factor which takes part in the image and the added-value of the wines of these areas. Parallel To the cultural attraction for the vine, the wine and tasting, “Œnotourisme” are often justified by an ecological approach of the cellars and soils.
Probabilistic modeling of the quality of a vineyard and deterministic modeling of the quality of a wine: first approaches
Objectively evaluating the quality of a vineyard is not always simple. We designed a probabilistic model that takes into account the parameters defining the status of the vineyard with their associated interactions. It is based on a Bayesian network, including an inference engine and software.
Discovering the consumer collective unconscious and personal sensory analysis applied for innovative assessment and marketing of wine
The art of wine urges mind and brain, “one and triune” because it has three main anatomic and functional which overlapped and integrated during (McLean, 2006), a synthesis of tactile and olfactory sensations related to memory iconic environment and territory, in a constellation of free associations that characterize the knowledge and feeling conscious and unconscious.
Effect of worldwide regions and climates on the sensory typicality of Pinot noir wines
In the context of the Academy of Vine and Wine of the GiESCO, a sensory analysis of 31 Pinot noir wines from different climates and regions worldwide has been organized. The results concern the general methodology and the characterization of the elements of typicality of the wines. A more precise study of the influence of climatic factors will be performed on such basis.
Climate variability and organoleptic profiles of Pinot noir worldwide
Wine typicity is revealed at various spatial scales, according to the variability of terroir components, which individual contribution change depending on the site. In this study, the impact of climate at global scale on the sensory profile of wine is examined.
Essential elements provided by philosophy and the evaluation methodology of the “great chain”, used in the algorithm of the sustainable “universal–metaethic” viticulture
Activities and research presented in this work conducted at international, European, national and local levels concretized in 1997 involved more than 2,500 personalities from various sectors, philosophical, existential-lifestyle, inter-religious, political, social, economic, commercial, scientific, technical, administrative, training, information, media, as well as common but wise citizens and especially farmers and mountain dwellers.
Evolution of phenolic compounds, organic acids and color parameters in tropical red wines during storage in bottles
The understanding of phenolic and organic acid variation during wine storage in the bottle is important, because the commercial aspects, mainly color, and their antioxidant properties. Faced on scientific reference scarcity about this subjected for the tropical wines, this study evaluated the mainly factors involved in their phenolic compounds and organic acid evolution and these influence on color stability.
Correlation between phenolic profile and antioxidant capacity of Brazilian tropical red wines
Phenolic compounds play an important role in oenology and exhibit antioxidant properties that are capable of reducing the risk of cardiovascular, inflammatory, carcinogenic, viral and bacterial diseases. However, correlation between phenolic profile and antioxidant activity of tropical wines are scarce.
Antioxidant activity of Brazilian tropical red wines in relation to its phenolic content
The purpose of this study was to analyze the antioxidant capacity of several samples of commercial wines produced in the São Francisco Valley – Northeast of Brazil to evaluate their dependence on vintage, winery and grape variety and to investigate their correlation with the total phenolic content. Wines from grape cultivars Cabernet Sauvignon, Petite Syrah, Ruby Cabernet, Syrah, Tannat and Tempranillo were evaluated, in triplicate, for total phenolic content by the Folin Ciocalteu’s reagent using gallic acid as a standard and for antioxidant activity, by the 2,2–diphenyl–1-picrylhydrazyl radical scavenging assay.
Non-invasive techniques to estimate the influence of rootstock on leaf and berry components of Pinot blanc grapevines
Beside the resistance against phylloxera the adaptation of rootstocks to different site properties e.g. soil pH, water availability, nutrition supply, lime content or salinity and management system of the vineyard are of major importance establishing a vineyard and balancing growth. Pinot Blanc (Vitis vinifera L.; clone Gm 2) were planted in 2003 at Geisenheim (Germany) and grafted on twenty different rootstocks.
Rootstock-scion interactions: nutrient uptake efficiency, water status, and canopy development
The performance of the cultivars Chardonnay, Merlot, Pinot gris and Pinot noir grafted onto nine rootstocks or on their own roots was evaluated over a three year period. A split block factorial design was used to compare the effect of the rootstocks Riparia Gloire de Montpellier (RGM), 101-14 MGt, 3309C, 110R, 5BB, 420A MGt, Gravesac, SO4, 44-53M, or ungrafted vines on the scion
Rootstock tolerance to drought, one way to deal with climate change
Water is the main factor limiting grape production under Mediterranean conditions. The vine water status also strongly impacts grape quality. In the present work, the rootstocks are considered as a way to cope with water deficit. Water use efficiency and conferred vigor related traits induced by some rootstocks in field conditions were compared to those measured in pots submitted to controlled water deficit.
Trial of ten common rootstocks on two different soils in the paso robles AVA of California
A total of 704 Cabernet Sauvignon (CS8) vines were grafted on 10 different rootstocks and compared to an own-rooted control as part of new vineyard planting on the terraces above the Estrella River in the Paso Robles AVA. The planting was done on two different sites, each underlain by a different soil type, within the same vineyard block.
Green manuring in horizontally terraced vineyards: A new approach
A number of studies in viticulture dealt with cover crops cultivated on the entire surface of every second alleyway, limiting spring soil trafficability to the non-cultivated ones. In order to guarantee soil trafficability of every alleyway in horizontally terraced vineyards, this study investigates a new approach to cultivate green manure cover crops in the central 60 cm-stripe of every alleyway.
Rootstocks impacts on vine performance and fruit composition of “Chambourcin” grapes
The use of rootstocks rather than own rooted vines, and the choice of the appropriate rootstocks for a specific cultivar depend on the interaction of the vineyard site, cultivar and the rootstock. In Midwest U.S.A., and in Missouri in particular, growers have mostly planted well adapted French American Vitis vinifera hybrids like Chambourcin (Vitis vinifera x V. rupestris) which is one of the most diffused wine grape cultivar in the area.
Rootstocks of grapevine: effects on vegetative development, production and grape quality of cv. Verdejo in the D.O. Rueda (Spain)
The grapevine rootstock should primarily allow the better adaptation of the vine to the soil, through the regulation of vegetative development, and avoid damage of soil pests, highlighting phylloxera and nematodes. Given the low knowledge of the effects of different rootstocks in the agronomic, physiologic and qualitative behaviour of Verdejo variety, a trial has been established in the Duero river Valley, in the location of Serrada (Valladolid), belonging to the Rueda D.O. This experimental trial was planted in 2004. The period of study has been 2007-2011.
