Bio‐metaethics viticulture proposed by the Giesco. Direct charter with producers. Example of evaluation of training systems

Context and purpose of the study. Cover cropping in vineyards supports grape yield, quality, and soil health.

Climate strongly affects the geographical distribution of grape varieties, grapevine cultivation techniques and wine organoleptic properties.

Several winemaking operations, such as filtration, pumping, and racking, are known to potentially facilitate the incorporation of atmospheric O2 into the wine. Control of grape must oxidation is one key aspect in the management of white wine aroma expression, color stability and shelf-life extension. On the one hand, controlled must oxidation may help to remove highly reactive phenolic compounds, which otherwise could contribute to premature oxidation. And on the other hand, in certain cases of extreme protection of the must from O2 (e.g. pressing under inert atmosphere), it can help to preserve varietal aromas and natural must antioxidants.

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

Aroma is one of the most important attributes that determine consumer’s perception of the sensory quality of wine and varietal typicity.
