Effect of Yeast Derivative Products on Aroma compounds retention in model wine


For many years, enological research has developed commercial formulates of yeast derivatives as stabilizing agents and technological adjuvants in winemaking. These products are obtained from yeast by autolytic, plasmolytic, or hydrolytic processes that liberate many macromolecules from the yeast cell, principally polysaccharides and oligosaccharides and most specifically mannoproteins that are well known for their ability to improve tartaric stability and to reduce the occurrence of protein hazes (Ángeles Pozo-Bayón et al., 2009; Charpentier & Feuillat, 1992; Morata et al., 2018; Palomero et al., 2009). The use of these products is now well developed in enological practices but a great concern has emerged on their effect on the sensorial characteristics of the wine. Indeed, it is well reported that wine macromolecules such as polysaccharides, mannoproteins, and polyphenols can interact with wine aromas, modifying their volatility and thus their sensorial impact to the overall bouquet of the wine (Comuzzo et al., 2006, 2011; Lubbers, Charpentier, et al., 1994; Lubbers, Voilley, et al., 1994; Pozo-Bayón et al., 2009; Rodríguez-Bencomo et al., 2014).
Our study aimed at getting a better microscale insight into the impact of yeast derivative products (YDP) on volatile compounds in wine. The impact of inactivated dry yeast, autolysate, cell walls, mannoproteins, and protein extract on the partition coefficient of six volatile compounds (isoamyl acetate, hexanol, ethyl hexanoate, linalol, 2 phenyl-ethanol, β-ionone) was studied in a model wine, at different aging times and under oenological conditions.
The originality of this work concerns the development of a Solid Phase Micro Extraction method for partition coefficient measurement that keeps the integrity of the thermodynamic of the sample during the phase of extraction. In the experimental conditions used in this study (YDP at 200 g/hL), the results obtained clearly show a retention effect of YDP on most of the aroma compounds tested. This retention was modulated by the nature of theYDP, the nature of the aroma, and the time of ageing. Further work will aim at getting a better understanding of the nature and the strength of interactions involved in the retention phenomena.

Physiological and growth reaction of Shiraz/101-14 Mgt to row orientation and soil water status

Advanced knowledge on grapevine row orientation is required to improve establishment, management and outcomes of vineyards on terroirs with different environmental conditions (climate, soil, topography) and in view of a future change to more extreme climatic conditions. The purpose of this study was to determine the combined effect of row orientation, plant water status and ripeness level on the physiological and viticultural reaction of Shiraz/101-14 Mgt.

Effects of mechanical leafing and deficit irrigation on Cabernet Sauvignon grown in warm climate of California

San Joaquin Valley accounts for 40% of wine grape acreage and produces 70% of wine grape in California. Fruit quality is one of most important factors which impact the economical sustainability of farming wine grapes in this region. Due to the recent drought and expected labor cost increase, the wine industry is thrilled to understand how to improve fruit quality while maintaining the yield with less water and labor input. The present study aims to study the interactive effects of mechanical leafing and deficit irrigation on yield and berry compositions of Cabernet Sauvignon grown in warm climate of California.

The effects of cane girdling on berry texture properties and the concentration of some aroma compounds in three table grape cultivars

The marketability of the table grapes is highly influenced by the consumer demand; therefore the market value of the table grapes is mainly characterized by its berry size, colour, taste and texture. Girdling could cause accumulation of several components in plants above the ringing of the phloem including clusters and resulting improved maturity. The aim of the experiments was to examine the effect of girdling on berry texture characteristics and aroma concentration.

Application of a fluorescence-based method to evaluate the ripening process and quality of Pinot Blanc grape

The chemical composition of grape berries at harvest is one of the most important factors that should be considered to produce high quality wines. Among the different chemical classes which characterize the grape juice, the polyphenolic compound, such as flavonoids, contribute to the final taste and color of wines. Recently, an innovative non-destructive method, based on chlorophyll fluorescence, was developed to estimate the phenolic maturity of red grape varieties through the evaluation of anthocyanins accumulated in the berry skin. To date, only few data are available about the application of this method on white grape varieties.

Different yield regulation strategies in semi-minimal-pruned hedge (SMPH) and impact on bunch architecture

Yields in the novel viticulture training system Semi-Minimal-Pruned Hedge (SMPH) are generally higher compared to the traditional Vertical Shoot Positioning (VSP). Excessive yields have a negative impact on the vine and wine quality, which can result in substantial losses in yield in subsequent vintages (alternate bearing) or penalties in fruit quality. Therefore yield regulation is essential. The bunch architecture in SMPH differs from VSP. Generally there is a higher amount but smaller bunches with lower single berry weights in SMPH compared to VSP.
