Productivity, quality, and thermal needs of the Piedirosso vine: four years of observations

Abstract

The effects of temperature on cv Piedirosso, indigenous of the Campania region (South of Italy), were tested in order to study its possible influence on grapevine and to discover how to optimize the qualitative expression of the cultivar. Relationships between evolution of the main must components, berry weight, and heat requirement of the cv Piedirosso were studied. The cv Piedirosso showed itself to be suitable to the area tested. We evidenced a reasonable agreement of the model of Amerine and Winkler’s estimation as to the thermal needs of cv Piedirosso. The heat requirement of the cultivar was determined in 1750-1850 degrees/day (DD) to obtain a sugar content of 21-22 °Brix, a pH of 3.10-3.20 and a titratable acidity of 8-9 g/l; to obtain a higher sugar content of musts (23-24 °Brix, pH of 3.2-3.3, titratable acidity of 8-9 g/l) the thermal needs is 1800-1900 DD.

Temperature variability inside a wine production area and its effect on vine phenology and grape ripening. An example from the Saint-Emilion-Pomerol

AIM: the aim of this study was to develop a method for fine-scale temperature zoning. The effect of temperature variability on vine phenology and grape composition was assessed in the production area of Saint-Emilion

Impact assessment of the reverse osmosis technique in wine alcohol management

Wine authenticity and composition can be influenced by a range of membrane separation processes as reverse osmosis. In the context of climate change, the natural trend is to obtain wines with higher alcoholic concentration when classical winemaking methods are employed, and this may induce alteration of typicity of wines by masking the olfactory and taste properties. This study aimed to evaluate the influence of reverse osmosis techniques used for decrease of ethanol content on the stable isotopic ratios as markers for wine authenticity characteristics.

New varieties descendant from Monastrell with lower sugar and high phenolic content adapted to warm climates

Given that climate change is a continuous process, it is necessary to constantly search for new strategies that help the viticulturist sector to mitigate its consequences. All adaptation strategies will have a greater or lesser effect that in turn will be marked by the times of action. As a long-term action, a genetic breeding program to obtain new varieties descendant from Monastrell has been developed in the Region of Murcia (more specifically, in the IMIDA Research Center) since 1997. In this program, new red varieties have been developed through directed crosses of the Monastrell variety with other varieties such as Cabernet Sauvignon, Tempranillo and Syrah.

How much does the soil, climate and viticultural practices contribute to the variability of the terroir expression?

When considering the application of a systemic approach to assess the intrinsic complexity of agricultural production, the following question immediately arises

Composition of grape grown on different Homogenous Terroir Units (HTU)

One cultivar could produce distinct wines with typical properties and qualities different depending on its cultivated and its mesoclimatic conditions.
