Influence of cover crops in a Tempranillo vineyard grown under the edaphoclimatic conditions of the Appellation of Origin Rueda

Abstract

The way to manage the vineyard soils has certainly changed in Spain during the last years. Traditionally, the vineyards were tilled, but this growing technique has been replaced in some vineyards by the bare soil with herbicide. Also, soil cover crops have started to be applied in some vineyards. The competition between the roots systems of the vines and the cover crop can influence on the capacity and the conditions of the plants for water absorption, transport of photosynthesized products to the roots, etc. Consequently, the cover crop can affect the water supply to the vine. The objective of this trial has been to study the behaviour of the Tempranillo variety under different alternatives of soil management, analysing the vegetative-productive vine balance and its influence on the grape quality, as well as the soil water content and the dry matter produced by the cover crop species. The trial has been carried out along 2006 and 2007 on a Tempranillo/110R vineyard, vertical trellis trained with Royat cordon pruning, with 3.00 m x 1.25 m vine spacing. The soil has homogeneus sandy-loam structure from the surface to the 110 cm depth, where there is a ground water table. The experimental treatments have been the following: TIL, traditional tillage (2006 and 2007); BAR, barley (Hordeum vulgare) (2006 and 2007); LEG, Vicia monanthos (2006) and vetch (Vicia sativa) (2007); PER, resident vegetation (2006) and or perennial vegetation, fescue (Festuca orundinacea) and ryegrass (Lolium perenne) combination at 50% (2007). The use of cover crop species in the inter-row space has provoked highly significant differences among treatments in yield, depending on the cover crop species and the annual climatic conditions. Legume and perennial species have shown to be more water competitive towards the vines than the rest of cover crops applied, which has reduced yield and vegetative development and has increased the dry matter produced by this species with respect to the others. The influence of the soil management on grape quality has not been determinant, in such a way that it has depended on the annual conditions and the level of yield, as well as on the cover crop species

The impact of cell wall composition of the extraction of anthocyanins and tannins from grape berries

Extraction of anthocyanins and tannins have been studied for two grape varieties, Carignan and Grenache, two maturation levels and two vintages, in model solutions and in wines, using UHPLC-MS/MS in the MRM mode  and HPSEC.

Determination of target compounds in cava quality using liquid chromatography. Application of chemometric tools in data analysis

According to the Protected Designation of Origin (PDO), Cava is protected in the quality sparkling wines made by the traditional Champenoise method were the wine realize a second fermentation inside the own bottle1. Geographical and human peculiarities of each bottle are the main way for the final quality2. The aim of this study is to find correlations and which target compounds are the most representative of the quality of two different grape varieties, Pinot Noir and Xarel·lo. The quality of these two types of grapes is being studied for each variety by a previous classification of the vineyard made by the company who provided the samples (qualities A,B,C,D, being A the better one and D the worst one). The target compounds studied are organic acids and polyphenols. The methodology for the determination of organic acids is HPLC-UV/vis and for some of them the enzymatic methodology.

Applications of a novel molecular phenology scale to align the stages of grape berry development

Phenology scales widely adopted by viticulturists (i.e., BBCH or modified E-L systems) are classification tools that describe seasonal and precisely recognized stages of fruit growth and development based on specific descriptors such as visual/physical traits or easy-to-measure compositional parameters.

Evolution of the metabolic profile of grapes in a context of climate change

In the current context of global climate change, anticipating the evolution of the oenological potential of emblematic grape varieties of regions such as Burgundy and Champagne is a guarantee of the sustainability of a sector which has considerable economic weight. however, if various models of climate change cast doubt on the sustainability of these grape varieties in these regions, appellation decrees, as well as consumer expectations, do not allow or consider the use of alternative grape varieties. In addition, control/compensation methods such as irrigation are also not permitted.

From vineyard to bottle. Rationalizing grape compositional drivers of the expression of valpolicella aroma ‘terroir’

AIM: Valpolicella is a renowned Italian wine-producing region (Paronetto, 1981). Wines produced in its different sub-regions are anecdotally believed to be aromatically different, although there is no systematic study addressing the chemical bases of such diversity
