Spatial variability of the nutrient distribution in Jerez vineyard soils (Spain)

Abstract

From a fertility standpoint, the vine has to extract from the soil mineral substances necessary for its existence. However, the amount of certain available nutrients does not always correspond to a proportional increase in quality. Such is the case with nitrogen and organic matter and is in contrast to that of P and K, whose presence has a positive relation to quality. Most of the vintage wines come from vineyards located on calcium-rich soils, which have a complex effect on their quality. It is therefore necessary to characterize the soil for fertilizer practices in an objective way. The production area of Jerez has a notable environmental variability due to the landscape morphology (hills and plains), soil characteristics and the climate conditions due to its oceanic proximity. To assess the fertility of the soils of different vineyards and detect potential imbalances that may impede the growth of the vine and affect its production, a study has been made of distribution parameters such as O.M., P, K, Ca and Fe available in three plots representing the area of Jerez (Cadiz, Spain).The results have shown that OM and Fe presented a greater homogeneity in their concentration for the entire sample area with variances ranging between 0.09 and 0.82, and between 36 and 90, respectively. For the other nutrients analyzed, the variation between different points within the controlled sample plots was very important, noting interval concentrations of 5900 to 12480 ppm for Ca, from 8 to 158 ppm for P and 342 to 1698 ppm for K. The differences observed in the surface horizon remained in the deeper layers.

Feminin vs masculin: the sensorial opposition between chambolle-musigny and gevrey-chambertin wines and the socioeconomical construction of a terroir/taste wine paradigm

At least since de XIXth century, wine writers oppose quite often the wines from Gevrey-Chambertin to the wines from Chambolle-Musigny claiming that the former are more “masculine” (full-bodied, powerful tannins, leathery, rustic…) and the later more “feminine” (delicate, elegant, silky, flowery…).

EFFECT OF MICRO-OXYGENATION IN COLOR OF WINES MADE WITH TOASTED VINE-SHOOTS

The use of toasted vine-shoots (SEGs) as an enological tool is a new practice that seeks to improve wines, differentiating them and encouraging sustainable wine production. The micro-oxygenation (MOX) technique is normally combined with alternative oak products with the aim to simulate the oxygen transmission rate that takes place during the traditional barrel aging. Such new use for SEGs implies a reduction in color due to the absorption by the wood of the responsible compounds, therefore, given the known effect that MOX has shown to have on the modification of wine color, its use together with the SEGs could result in an interesting implementation with the aim to obtain final wines with more stable color over time.

Does the sustainability perception depend on the Terroir?

The main scope of this research has been to investigate what values are attributed to the concept of “sustainability” by the wine producers of two different wine territories of Piedmont; the terroir of the Barolo DOCG and the the terroir of the Gavi DOCG. The research wants to emphasize how much the characteristic elements of each terroir influence the perception of the concept of sustainability among producers.
