Climate effect on ripening process in Vitis vinifera, L. cv. Cencibel

Abstract

A seven years survey (2003 to 2009) has been carried out over old traditional vineyards cv. Cencibel in La Mancha region (Spain). Seven plots with more than 35 years old were sampled from veraison to harvest, measuring soluble solids (ºBaumé) and acid concentration (g/l in tartaric acid). The ripening process was different each year depending on season climate character (vintage). The monthly mean temperatures (April to September) and the rainfalls accumulated (April to September) have been studied and these factors have been related with the date of vintage and the colour intensity (very important parameter for wine quality). The growing-degree day (GDD) for the variety Cencibel (1551,1ºC) has been calculated.
The temperature of May is critical for the development of photosynthetic apparatus of the vineyard and thus, conditions all the ripening process. It has been found two different models of vintage: mild-fresh year (2004, 2007 and 2008) and warm year (2003, 2005, 2006 and 2009). In the warm conditions of La Mancha it is very desirable a delay in the ripening process. As the later will be the process, the cooler will be the nights at the end of ripening. This will improve the quality of the vintage, as it happened in the fresh years.

Clones of 10 Vitis vinifera varieties: degree of inter- and intra-varietal variation and putative mechanisms underlying clonal variability

Context and purpose of the study. Intra-varietal variability for key physiological and oenologically important traits can be exploit in viticulture following the consistently higher environmental pressure driven by climate change.

Investigation of cellulose nanofiber-based films used as a protective layer to reduce absorption of smoke phenols into wine grapes

Volatile phenols from wildfire smoke are absorbed by wine grapes, resulting in undesirable smoky and ashy sensory attributes in the affected wine.[1] Unfortunately the severity of wildfires is increasing, particularly when grapes are ripening on the vine. The unwanted flavors of the wine prompted a need for solutions to prevent the uptake of smoke compounds into wine grapes. Films using cellulose nanofibers as the coating forming matrix were developed as an innovative means to prevent smoke phenols from entering Pinot noir grapes. Different film formulations were tested by incorporating low methoxy pectin or chitosan.

From protein-centered to gene-centered approaches to investigate DNA-protein interactions in grapevine

DNA-binding proteins play a pivotal role in critical cellular processes such as DNA replication, transcription, recombination, repair, and other essential activities. Consequently, investigating the interactions between DNA and proteins is of paramount importance to gain insights into these fundamental cellular mechanisms. Several methodologies have been devised to uncover DNA-protein interactions, which can be broadly categorized into two approaches. The “protein-centered” approach focuses on identifying the DNA sequences bound by a specific transcription factor or a set of TFs. Techniques falling within this category include chromatin immunoprecipitation, and protein-binding microarrays.

Closure permeability: a key parameter for modulating the aroma of monovarietal white wines during bottle ageing

Bottle aging is crucial for wine quality, influencing its chemical and sensory properties [1]. Ideally, a phase of qualitative ageing enhances sensory attributes before a decline in quality occurs. Understanding the impact of oenological variables on these phases is a key challenge in modern winemaking.
