Conservation of intravarietal diversity in France: exhaustive overview and perspectives

Since the renewal of the French vineyard after the Phylloxera crisis, the panorama of cultivated varieties has dramatically changed. This current genetic erosion is due to the increasing interest in some cultivars that are widely spread out. Meanwhile, clonal selection has contributed to the development of these grape varieties driving towards a massive loss of […]

Varieties and rootstocks: an important mean for adaptation to terroir

A large genetic diversity exists among V. vinifera varieties, but also among cultivated rootstocks. This diversity is important to adapt plant material to different environmental conditions and contributes to the expression of terroir. Plasticity, i.e. the level of modification of the expression of individual characteristics of a genotype in different environments, is also important for […]

Unexpected relationships between δ13C, water deficit, and wine grape performance

Water nutrition is crucial for wine grape performance. Thus soil investigation aims at characterizing spatial and temporal variability of available water. A possible strategy is to integrate monitoring and proxies of water availability. The carbon isotope ratio δ13C, measured in the alcohol of wine, is a promising tool to determine water stress during the vine […]

Impact of organic inputs on soil biodiversity in vineyard systems. A monitoring approach during 20 years

Conventional vineyard practices have lead in many environmental disturbances as erosion, soil compaction, loss of organic matter and soil biodiversity, water contamination… Therefore, there is an increasing interest to develop sustainable viticulture in the famous Champagne vineyard for 20 years: a program called “VITI 2000” has been developed since 1986 by CIVC (Inter-professional Committee of […]

Mapping intra-plot topsoil diversity of Burgundy vineyards (Aloxe-Corton, France) from very high spatial resolution (VHSR) images

In this work, we present a method based on very high spatial resolution (VHSR) aerial images acquired in the visible domain and that map soil surface diversity at the hillslope scale with a spatial resolution of a few centimeters. This method combines aerial VHSR image classification with local soil sampling. Principal component analysis (PCA) and […]

Contribution of soil for tipifiyng wines in four geographical indications at Serra Gaúcha, Brazil

Brazil has a recent history on geographical indications and product regulation for high quality wines. The first geographic indication implemented was the Vale dos Vinhedos Indication of Procedence (IP), within the wine production zone named Serra Gaúcha, northeast of State Rio Grande do Sul. During the last decade, the Vale dos Vinhedos ascended to the […]

Soil chemistry as a measure of the distinctiveness of american viticultural areas of the Columbia basin, USA

The Columbia Basin, a semi-arid region centered in the eastern part of Washington State, is the second largest wine grape growing region in the United States and presently contains 10 American Viticultural Areas (AVAs). Eight of the Columbia Basin’s AVAs are smaller subdivisions (sub-AVAs) of the 46,100 km2 Columbia Valley AVA. Although legally distinct, the […]

Grapegrowing soils

The soil plays a key role in viticulture since it defines the planting depth, development and aeration of the root system and also controls the absorption of mineral elements and water conditions of the plant (1). Topography has been considered a determinant of the quality of wine from the Roman Empire; however, the classical treatises […]

Observation and modeling of climate at fine scales in wine-producing areas

Global change in climate affect regional climates and hold implications for viticulture worldwide. Despite numerous studies on the impact of projected global warming on different regions, global atmospheric models are not adapted to local scales and impacts at fine scales are still approximate. Although real progress in downscaling, using meso-scale atmospheric models taking surface characteristics […]

ECA&D: A high-resolution dataset for monitoring climate change and effects on viticulture in Europe

Climate change will lead to persistent changes in temperature and precipitation patterns which will affect the characteristics of wine produced in each region. The European Climate Assessment and Dataset (ECA&D) is a web-based database and tool to monitor climate variability and trends over Europe. This tool is used in this study to analyse the viticulture-specific […]
