Vineyard soils characterization and its influence on the grape quality of cv. Carmenère in the Maipo Valley, Chile

Abstract

Produced since 1998, the De Martino Single Vineyard Carmenère is the first Carmenère Icon wine of Chile. The grapes are coming form a plot of 11 ha in Isla de Maipo, where the technicians of the winery have developed knowledge of their work, resulting in 3 levels of quality of the grapes. Normally harvested with no precision, this study is oriented towards the understanding of the differences in the quality of the Carmenère, mainly caused by different kinds of soils, and also the development of an accurate cartography of the different terroir units. The zonage of terroir units, made by filed observations of the vines and the soils physical properties, plus electric conductivity of soils and NDVI analysis allows the oenological team to make a selected harvest in 2007. Finally, different stages of sensorial analysis where developed to follow the resultants of this work for his first year.

Projected impacts of climate change on viticulture over France wine-regions using downscalled CMIP6 multi-model data

Winegrape is a crop for which the quality and the identity of the final product depends strongly on the
climatic conditions of the year. By impacting production systems and the way in which wines are
developed, climate change represents a major challenge for the wine industry (Ollat et al., 2021).

Crop water stress index as a tool to estimate vine water status

Crop Water Stress Index (CWSI) has long been a ratio to quantify relative plant water status in several crop and woody plants. Given its rather well relationship to either leaf or stem water potential and the feasibility to sample big vineyard areas as well as to collect quite a huge quantity of data with airborne cameras and image processing applications, it is being studied as a tool for irrigation monitoring in commercial vineyards. The objective of this paper was to know if CWSI estimated by measuring leaf temperature with an infrared hand held camera could be used to substitute the measure of stem water potential (SWP) without losing accuracy of plant water status measure.
