Cover crop influence on water relations, yield, grape and wine composition of Pinot noir

Abstract

The effect of cover crop on the water relations, yield and grape composition of Pinot noir vines was investigated during two seasons (2003 and 2004) in a gravely soil located in Tarragona (Spain). Seventeen-year-old vines, grafted onto R110 and trained onto a Ballerina training system, were used. Treatments (Rye grass and a clean tillage control) were replicated four times in a block layout. Leaf water potential was measured during mid-day at pea size, véraison and ripeness stages. Berry composition was determined at ripeness. At harvest, yield components were determined and one wine made per treatment. Severe water stress occurred in 2003, which resulted in the grass cover treatment producing less leaf area per vine and a reduction in leaf water potential during the day. However, in 2004, significant differences occurred only at 8:00. The same pattern was observed for berry weight and the yield parameters; they were lower in 2003 with cover grass. The anthocyanin content, total soluble solids and titratable acidity decreased strongly after véraison, only in 2003. Grass cover had a negative effect on total phenol and alcohol contents of wines in the extremely dry year. Contrasting effects were found in 2004.

Acumulación de materia seca, orientada a valorar la fijación de carbono, en función del aporte de riego y la pluviometría, en Cabernet-Sauvignon a lo largo de 15 años

The vineyard is capable of fixing carbon in its permanent structure from atmospheric carbon dioxide, through the process of gas exchange and the performance of photosynthesis. The photosynthetic capacity of the vineyard depends on the water resources that the plant may have at its disposal, so the amount of dry matter, derived from the processed photosynthates, that it can store will depend on the water regime of the crop, both in the annually renewable organs as in permanent parts.

Exploring diversified service offerings in the Spanish wine industry

The spanish wine industry stands at a crossroads, transitioning from a traditional emphasis on wine production to a landscape increasingly characterized by diversified service offerings. This paper delves into the nuances of servitization within spanish wineries, investigating the determinants of servitization and the impact of these diversified services on revenue streams. The paper posits hypotheses concerning the influence of various factors, such as winery size, location, market orientation, ownership structure, market competition, regulatory environment, market demand, firm capabilities, owner characteristics, and firm age, on the adoption of diversified service offerings in spanish wineries. The methodology involves comprehensive regression analysis to unravel the drivers of servitization within this context.

CHARACTERIZATION AND IDENTIFICATION OF YEAST BIOACTIVE PEPTIDES RELEASED DURING FERMENTATION AND AUTOLYSIS IN MODEL WINE

Aging wine on lees is a consolidated practice during which some yeast components (e.g., polysaccharides,
proteins, peptides) are released and solubilized in wine thus, affecting its stability and quality.
Apart from the widely studied mannoproteins, the role of other yeast components in modulating wine
characteristics is still scarce. Wine peptides have been studied for their contribution to taste, antioxidant,
and antihypertensive potentials. However, the peptides detected in wine can be influenced by the
interaction between yeasts and grape components.
