Application of remote sensing by unmanned aerial vehicles to map variability in Ontario Riesling and Cabernet Franc vineyards
The objective of this investigation was to verify usefulness of proximal sensing technology and unmanned aerial vehicles (UAVs) for mapping variables e.g., vine size (potential vigor), soil and vine water status, yield, fruit composition, and virus incidence in vineyards.
Environmental influence on grape phenolic and aromatic compounds in a Nebbiolo selection (Vitis vinifera L.)
Nebbiolo (Vitis vinifera L.) is one of the most important wine red cultivar of North-west Italy. A better understanding of the complex relations among grape aromatic and phenolic maturity and environmental factors may strongly contribute to the improvement of the quality of Nebbiolo wines.
Terroir effects from the reflectance spectra of the canopy of vineyards in four viticultural regions
Knowledge of the reflectance spectrum of grape leaves is important to the identification of grape varieties in images of viticultural regions where several cultivars co-exist.
Introducing heterogeneity measurements in terroir studies. Application in the região demarcada do douro (n portugal)
Terroir zoning studies have to manage the heterogeneity and complexity of the landscape properties and processes. The varying geology is one of the main landscape properties conditioning the spatial variability of terroirs.
Spatial suitability analysis for site selection of vineyards using biophysical models and computational intelligence
Developing a sustainable agricultural production system and acquiring the full potential of land resources requires employing land-use assessment. This entails knowledge of the climate, soil, and topography of the area of interest.
Remote sensing applications in viticulture: recent advances and new opportunities
Remote sensing applications in viticulture have been a research theme now for nearly two decades, becoming a valuable tool for vineyard management. Metrics produced using remotely sensed images of vineyards have yielded relationships with grape quality and yield that can help optimise vineyard performance
Talking about terroir
When talking about terroir, scientists and lay wine tasters, very much including wine journalists and wine growers, too often talk past one another.
Vineyards and grape varieties: what is going on in wine professional and consumer minds?
Vineyard and grape variety are two popular ways of classifying wines. Vineyard designation is a traditional practice for European wine labels but is being increasingly replaced by grape variety designation, mainly used for New World and Swiss wine labels.
The pyramidal organization of AOC in France: a process of identification and valorisation of terroirs
English version: Result of their history, some famous French wine countries such as Burgundy, Bordeaux or Alsace, have a hierarchical organization of their Appellations of Controlled Origin (AOC): AOC regional, communal, Premier Cru, Grand Cru.
Irrigation and terroir: two opposite concepts? Point of view of international experts and french consumers
At long term, qualitative irrigation seems to be the most systematic, if not the best, cultural practice for dealing with climate change and yield increases without decrease grape quality.
Climate change and economic challenge – strategies for vinegrowers, winemakers and wine estates
For wine areas around the world, nature and climate are becoming factors of production whose endowment becomes a stake beyond the traditional economic factors: labor, capital, land. They strongly influence agricultural and environmental conditions for production.
The soil biodiversity as a support to environmental sustainability in vineyard
The environmental biodiversity is important to guarantee essential services to the living communities, its richness is a symptom of a minor disturbance and improves he environment biological quality.
Regenerative agricultural winegrowing systems play a role in refining the expression of terroir in the pacific coast region of United States and Canada
By definition, Regenerative Agricultural Systems seek to promote soil and plant health by using photosynthesis for the removal and retention of atmospheric carbon dioxide into stable soil carbon.
Which risk assessment of water quality in pdo vineyards in Burgundy (France)?
To meet the demand of assessment tool of water managers we adapted to the vine production the INDIGO® method to developed initially for arable farming at the field scale.
Spontaneous fermentation dynamics of indigenous yeast populations and their effect on the sensory properties of Riesling
Varietal Riesling aroma relies strongly on the formation and liberation of bound aroma compounds. Floral monoterpenes, green C6-alcohols, fruity C13-norisoprenoids and spicy volatile phenols are predominantly bound to disaccharides, which are produced and stored in the grape berry during berry maturation.
Effects of environmental factors and vineyard pratices on wine flora dynamics
he intensification of t vineyard practices led to an impoverishment of the biological diversity. In vineyard management, the reflection to reduce pesticides uses concerns mainly the soil management of the vineyard, and often focuses on flora management in the inter-row.
Microclimatic differences in fruit zone of vineyards on different elevations of ‘nagy-eged hill’ in eger wine region, Hungary
The Bull’s Blood of Eger (‘Egri Bikavér’) is one of the most reputed red wines in Hungary and abroad, produced in the Northeastern part of the country.
Ten grapevine rootstocks: effects on vegetative development, production and grape quality of cv. Mencia in the d.o. Bierzo (Spain)
Grapevine rootstock is basic to achieve good adaptation of the vine to ground and environment.
The pedoclimatic conditions impact the yeast assimilable nitrogen concentration in the grapevine must and the valorisation of foliarnitrogen fertilisation
Aims: Agroscope investigated the efficiency of nitrogen fertilisation via foliar urea application at veraison with the aim of raising the yeast assimilable nitrogen (YAN) concentration in the musts
Effects of future climate change on grape quality: a case study for the Aglianico grape in Campania region, Italy
Water deficits limit yields and this is one of the negative aspects of climate change. However, this applies particularly when emphasis is on biomass production (e.g. for crops like maize, wheat, etc.)
