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

Abstract

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 into account, was realized over the past years, no operative model is in use yet to simulate climate at local scales (hundreds of meters). The TERVICLIM and TERACLIM programs aim at observing climate at local scales in different wine producing regions worldwide; simulating both climate and climate change in order to produce a fine scale assessment of the climate change impacts, thereafter simulating scenario of adaptation for viticulture, providing guidance to decision-makers in the viticultural sector.

2018 updates on the agronomic performances of fungus resistant wine grapes in Trentino (Italy)

On the market there are several wine grapes which are tolerant to the main fungal diseases. These varieties, commonly defined “resistant”, were developed in the grapevine breeding programs carried out mainly in Germany, France, Hungary and Italy. Some of these cultivars have been included in the national catalogues of wine grape varieties and have sometimes been allowed for specific kinds of wine. The VEVIR project, aimed at the enological evaluation of resistant vines, involves 33 cultivars achieved at the State Institute for Viticulture Freiburg in Germany, the Research Institute of Viticulture and Enology Pecs in Hungary and the Fondazione Edmund Mach S. Michele all’Adige (FEM) in Italy.

Intelligent use of ethanol for the direct quantitative determination of volatile compounds in spirit drinks

The quality of any alcoholic beverage depends on many parameters, such as cultivars, harvesting time, fermentation, distillation technology used, quality and type of wooden barrels (in case of matured drinks), etc.; however, the most important factor in their classification is content of volatile compounds.
