Climate, Viticulture, and Wine … my how things have changed!

Abstract The planet is warmer than at any time in our recorded past and increasing greenhouse emissions and persistence in the climate system means that continued warming is highly likely. Climate change has already altered the basic framework of growing grapes for wine production worldwide and will likely continue to do so for years to […]

Influence of weather and climatic conditions on the viticultural production in Croatia

The research includes an analysis of the impact of weather conditions on phenological development of the vine and grape quality, through monitoring of four experimental cultivars (Chardonnay, Graševina, Merlot and Plavac mali) over two production years. In each experimental vineyard, which were evenly distributed throughout the regions of Slavonia and The Croatian Danube, Croatian Uplands, Istria […]

Analysis of Cabernet Sauvignon and Aglianico winegrape (V. vinifera L.) responses to different pedo-climatic environments in southern Italy

Water deficit is one of the most important effects of climate change able to affect agricultural sectors. In general, it determines a reduction in biomass production, and for some plants, as in the case of grapevine, it can endorse fruit quality. The monitoring and management of plant water stress in the vineyard is critical as […]

Impact of climate change on the viticultural climate of the Protected Designation of Origin “Jumilla” (SE Spain)

Protected Designation of Origin “Jumilla” (PDO Jumilla) is located in the Spanish provinces of Albacete and Murcia, in the South-eastern part of the Iberian Peninsula, where most of the models predict a severe impact of climate change in next decades. PDO Jumilla covers an area of 247,054 hectares, of which more than 22,000 hectares are […]

Bioclimatic shifts and land use options for Viticulture in Portugal

Land use, plays a relevant role in the climatic system. It endows means for agriculture practices thus contributing to the food supply. Since climate and land are closely intertwined through multiple interface processes, climate change may lead to significant impacts in land use. In this study, 1-km observational gridded datasets are used to assess changes […]

Mesoclimate impact on Tannat in the Atlantic terroir of Uruguay

The study of climate is relevant as an element conditioning the typicity of a product, its quality and sustainability over the years. The grapevine development and growth and the final grape and wine composition are closely related to temperature, while climate components vary at mesoscale according to topography and/or proximity to large bodies of water. […]

A predictive model of spatial Eca variability in the vineyard to support the monitoring of plant status

In a vineyard, plant water status variability is strongly dependent on soil spatial variability, whose physical characteristics drive the processes involved in the soil water balance. More the soil and its characteristics vary in space (horizontally and vertically), more the productive and qualitative vine performances will be non-homogeneous. In this context, the proximal sensing of […]

Short-term relationships between climate and grapevine trunk diseases in southern French vineyards

An increasing plant dieback has been observed in vineyards these past two decades, that has been partly attributed to the incidence of grapevine trunk diseases. Among them, esca and Botryosphaeria dieback are increasingly affecting grapevine mortality and yield loss, but little is known about the relationships between leaf symptoms and climate, hampering our ability to […]

Effects of machine-simulated extreme weather events on grapevine ripening

Hail is a major challenge in viticulture, as it can damage both the vine’s canopy and its grapes. In practice, hail-damaged berries are often removed manually in order to reduce or eliminate negative impacts on wine quality. In order to determine the influence of hail damage and subsequent removal of damaged berries on the ripening […]
