New methods and technologies to describe the environment

New methods and technologies to describe the environment in terroir studies

The concept of terroir in viticulture deals with the influence of environmental factors on vine behaviour and grape ripening. Recent advances in technology, in particular computer technology, allow a more in-depth study of the environment. Geomorphology can be studied with digital Elevation Models (DEM). Soils can be surveyed with geophysics. ...

Using atmospheric and statistical models to understand local climate and assess spatial temperature variability at a fine scale over the Stellenbosch wine district, South Africa

Atmospheric and statistical models were used to increase understanding of potential climatic impacts, resulting from mesoscale physical processes that cause significant temperature variability for viticulture within the Stellenbosch Wine of Origin district. Hourly temperature values from 16 automatic weather stations and 40 tinytag data loggers located in the vineyards were ...

Historic and future climate variability and climate change: effects on vocation, stress and new vine areas

Climate, grapes, and wine: structure and suitability in a variable and changing climate

Climate is a pervasive factor in the success of all agricultural systems, influencing whether a crop is suitable to a given region, largely controlling crop production and quality, and ultimately driving economic sustainability. Climate’s influence on agribusiness is never more evident than with viticulture and wine production where climate is ...

The impact of global warming on Ontario’s icewine industry

Ontario’s wine regions lie at the climatic margins of commercial viticulture owing to their cold winters and short cool growing season. The gradual warming of northern latitudes projected under a human-induced climate change scenario could bring mixed benefits to these wine regions. On the one hand, climate change could moderate ...

Influence of soil characteristics on vine growth, plant nutrient levels and juice properties: a multi-year analysis

Soil physical and chemical properties affect vine nutrition, as indicated by leaf and petiole nutrient content, in a way that may directly impact wine properties. The goal of this multi-year project is to study the relationship between vineyard soils and the wines produced on them using a variety of biogeochemical ...

Three proximal sensors to estimate texture, skeleton and soil water storage in vineyards

Proximal sensors are becoming widely used in precision viticulture, due to the quick, easy and non-invasive identification of soil spatial variability. The apparent soil electrical conductivity (ECa) is the main parameter measured by sensors, which is correlated to many factors, like soil water content, salinity, clay content and mineralogy, rock ...

Landscape and its emotional role in wine quality

The importance of landscape in wine quality perception: l’importanza del paesaggio nella percezione qualitativa del vino

The wine quality is a characteristic that is both difficult to define and communicate, because the quality attributes can be divided into intrinsic (objective, such as alcohol degree, acidity, colour, grape variety etc.) and hedonistic components (extrinsic) that is based upon a subjective evaluation. That means that the attributes that ...
