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 […]

Impact of microclimate on berry quality parameters of white Riesling (Vitis vinifera L.)

Knowledge has been accumulated on the impact of microclimate, in particular berry temperature and irradiation, for a wide range of red varieties. However, little research has been dedicated on the effects of the same factors on the quality of white grape varieties. In this study we present results of the effects of microclimate on the […]

The complex response of Mediterranean viticultural systems to climate change: a case study from France and Australia

Climate change could put at risk viticultural areas situated at the hotter margins of Vitis vinifera growth climatic range. We focus on two such regions with a Mediterranean climate (CSb type in Köppen classification): Côtes-du-Roussillon in southern France and McLaren Vale in South Australia. They share a relatively similar recent climate evolution. Based on data […]

High resolution climate spatial analysis of European winegrowing regions

Climate strongly affects the geographical distribution of grape varieties, grapevine cultivation techniques and wine organoleptic properties. The current study aims at comparing the climatic features of European winegrowing regions. A geodatabase of 260 wine producing areas within 18 countries of the European Community was first established by means of maps collected from various sources (e.g. […]

Zoning mountain landscapes for a valorisation of high identity products

Mountain agriculture is made difficult by the geomorphological complexity of the territory. This is especially true for viticulture: over the centuries the work of men in such a difficult environment has produced unique, and valuable landscapes. Whereas some of these mountain viticultural sites have earned a place in the World Heritage List of UNESCO, not […]

Using multifactorial analysis to evaluate the contribution of terroir components to the oenological potential of grapes at harvest

The oenological potential of grapes at harvest depends on a combination of the major components of Terroir: the climate, the soil, the plant material, the training system and the crop management. They control the type of product that can be developed, providing adapted winemaking techniques.Due to the high variability of each of the Terroir components, […]

Aromatic stability of Syrah and Petit Verdot tropical wines from Brazil

The production of fine wines in the Sub-middle of the São Francisco River Valley, Northeast of Brazil, is relatively recent, about twenty-five years ago. This region presents different characteristics, with a tropical semiarid climate, in a flat landscape. Presenting high annual average temperature, solar radiation and water in abundance for irrigation, it’s possible the scaling […]

Climatic groups in Ibero-America viticulture compared to worldwide wine producer regions

The wine production is an important activity in many Ibero-American countries. The wine producer regions of these countries configure a large use of different climate types and viticultural climates. In a vitivinicultural zoning project of CYTED (Ibero-American Program for Science, Technology and Development), a viticultural climatic characterization was done in this macro viticultural region. The […]
