Estudio comparativo del potencial enológico de dos varietales tintos cultivados en la isla de Tenerife

Abstract

En el presente trabajo se ha realizado un estudio comparativo entre los varietales tintos Listán negro y Negramolle en la Denominación de Origen Tacoronte-Acentejo. Se han determinado durante dos años, los parámetros clásicos de maduración, el contenido en fenoles, los antocianos y los antocianos extraibles. Así mismo, se llevaron a cabo vinificaciones experimentales con dichos cultivares en orden a determinar no solo el potencial sino también su aptitud enológica. Del análisis de los resultados obtenidos sobre las uvas en maduración, se desprenden unos valores más adecuados de pH y contenido en potasio en la variedad Negramolle frente a la Listán negra, y un contenido en materia colorante potencialmente inferior en la variedad Negramoll. Sin embargo, estudiando la evolución frente al tiempo de los vinos elaborados, el contenido en antocianos y fenoles totales decae más rápidamente en la variedad Listán negra, manteniéndose más estable la variedad Negramolle.

Anthocyanin and trans-resveratrol accumulation is associated with abscisic acid and methyl jasmonicanthocyanin and trans-resveratrol accumulation is acid in berry skin of vitis vinifera L. Cvs. Malbec, Bonarda, Syrah, Cabernet sauvignon, and Pinot noir

Red grapes contain significant amounts of phenolic compounds, known to contribute to wine quality and to provide important health benefits. Berry skin phenolics can be elicited by plant hormones. The aim of this work was to increase the content of anthocyanins and trans-resveratrol in five red varieties cultured in Argentina: Malbec (M), Bonarda (B), Syrah (S), Cabernet Sauvignon (CS), and Pinot Noir (PN), in two different growing regions: Santa Rosa (SR) and Valle de Uco (VU), by applying a post-veraison hormonal treatment with abscisic acid (ABA) and methyl jasmonate (MeJA).

Addition of Malvasia di Candia Aromatica must and marcs to Golden Ale beer wort to obtain different Italian Grape Ales

Nowadays, the recovery of secondary resources of wine industry is insufficient and the developing of new products and adjuvants from secondary raw materials could become a relevant sector of research. The re-use of byproducts derived from winemaking could improve the sustainability of wine industry and give additional value to other food industries

Effect of scion-rootstock combinations on the performance of a near-infrared (NIR) spectroscopy method for determining vine water status

In the context of sustainable viticulture, modern and efficient techniques to determine water status are required to optimize irrigation practices. Proximal techniques such as thermography and spectroscopy have shown promising results. When these techniques are incorporated into mobile systems is possible to evaluate the water status on-the-go, offering the possibility to generate variability maps. However, in most cases, complex protocols of data acquisition and analysis are required. Also, the inherent physiological behaviour of the plants under certain water stress conditions needs to be considered. Therefore, the aim of this study was to evaluate the effect of scion-rootstock combinations on the performance of a predefined plant-based method based on proximal near-infrared (NIR) spectroscopy.
