Heat requirements for grapevine varieties is essential information to adapt plant material in a changing climate

Abstract

Precocity for fruit ripening is a genetically determined characteristic that is highly variable from one cultivar to another. In traditional wine-growing regions of Europe, growers have used this property to adapt the vines to local climatic conditions in order to maximize terroir expression. Due to global warming, the choice of later ripening grapevine varieties might be necessary in many regions to maintain late ripening conditions favourable for terroir expression. Hence, precise heat requirement data for each grapevine variety is essential information. Phenology (budburst, flowering, veraison and ripeness) and temperature data have been collected for many varieties in a wide range of locations over a great number of vintages. Heat summations base of 10°C were calculated for each variety to reach key phenological stages. However, a more sophisticated agro-climatic model might be necessary to increase the precision of a classification of varieties according to their precocity.

Nutrients and heavy metals in a vineyard soil under organic, biodynamic and conventional management

Promoting sustainable agricultural practices is one of the challenges of the last decades. Organic and biodynamic viticulture can be an alternative to intensive viticulture, furthermore contributing to reduction of impact on environment and human health and guaranteeing soil preservation and quality products1. The aim of this experimentation was to evaluate the medium and long-term effects of different agronomic practices in viticulture on nutrient availability and heavy metal accumulation in soil.

CONTRIBUTION OF VOLATILE THIOLS TO THE AROMA OF RIESLING WINES FROM THREE REGIONS IN GERMANY AND FRANCE (RHEINGAU, MOSEL, AND ALSACE)

Riesling wines are appreciated for their diverse aromas, ranging from the fruity fresh characters in young vintages to the fragrant empyreumatic notes developed with aging. Wine tasters often refer to Riesling wines as prime examples showcasing terroir, with their typical aroma profiles reflecting the geographical provenance of the wine. However, the molecular basis of the distinctive aromas of these varietal wines from major Riesling producing regions in Europe have not been fully elucidated. In this study, new lights were shed on the chemical characterization and the sensory contribution of volatile thiols to Riesling wines from Rheingau, Mosel, and Alsace. First, Riesling wines (n = 46) from the three regions were collected and assessed for their aroma typicality by an expert panel.

Natural glycolipids for the control of spoilage organisms in red wine

A natural glycolipid mixture obtained from the edible mushroom dacryopinax spathularia (“glycolipids”) is known to be an effective and approved antimicrobial treatment in non-alcoholic beverages at concentrations ranging from 5 – 100 mg/l. It has found a place alongside DMDC for the provision of microbial stability in soft drinks. These properties make the natural and sustainably produced glycolipids a promising candidate for the supplementation or replacement of SO2 in different winemaking processes.
