Estudio de fertilidad en variedades blancas en Castilla-la Mancha

Many winegrape regions have hillside vineyards, where vine water use is affected by vine age, density and health, canopy size, row orientation, irrigation practices

Climate change will increase the frequency of water deficit experienced in certain european regions, due to increased evapotranspiration and reduced rainfall during the growing cycle. We therefore need to find ways of adaption, including the use of more drought-tolerant planting material. In addition to the varieties used as grafts and involved in the wine ypicity of our wines, rootstocks selection is a relevant way of adapting to more restrictive environmental conditions.

AIM: Firm tissues of grapes and yeast are the major sources of lipids in wine.

No other agricultural product has a stronger relationship with the soil than wine. This study aimed to characterize the sensory profile of red wines from the Douro Demarcated Region (RDD) certified as DOC Douro, through the application of Quantitative Descriptive Analysis (QDA®) and Temporal Dominance of Sensations (TDS) sensory methods. QDA® provides a complete word description for all a product’s sensory properties. The TDS, which is relatively recent in the sensory field [1], allows to evaluation and description of the evolution of the dominant sensory perceptions during the tasting of a food product.Eighteen commercial wines from different producers were evaluated, six different samples representing each of the three sub-regions of the RDD.

The chemistry of wine is particularly complex due to biochemical and chemical interactions that significantly modify its organoleptic characteristics and stability over time. Aging on lees is a well-known practice during which various compounds are released, ensuring wines oxidative stability and its overall sensory quality [1,2].
