Targeted UHPLC-QqQ-MS/MS metabolomics for phenol identification in grapevine and wine: study of a Tempranillo clone with a dark-blue berry colour


Grapevine vegetative multiplication allows the accumulation of spontaneous mutations and increase intra-cultivar genetic diversity that can be exploited to maintain grape wine quality, tipicity and adaptation to different climate conditions. Non-volatile phenolic compounds are intrinsic components of grape fruits and derived products, particularly wine. They constitute a heterogeneous family of compounds and play an important role on the sensorial attributes of wine because they are responsible for some of important organoleptic properties as colour, flavour, bitterness and astringency. In the present study, we used a targeted metabolomics approach based on ultra-high performance liquid chromatography with tandem mass spectrometry (UHPLC-QqQ-MS/MS) to study the anthocyanin and non-coloured phenol profiles of a singular Tempranillo clone (Tempranillo negro or VN21), characterized by a dark-blue color in grape berry skin, as compared to RJ43, one of the most cultivated clones in D.O.Ca. Rioja (Spain). In addition, we investigated differences between VN21 and RJ43 clones, in the phenolic transference from grape to wine at different phases of the winemaking process. The results showed that anthocyanin and non-colored phenol content was higher in VN21 grape skin and seeds than in RJ43. With respect to anthocyanins, the singular color of grape skin in VN21 could be explained by higher concentrations of peonidin and cyanidin derivatives. Regarding non-colored phenols, the main differences were observed for proanthocyanidins and stilbenes concentration in grape skin and more importantly in seeds. Those content differences observed in berries were enhanced in the VN21 wines, displaying significantly higher concentrations of anthocyanins, as well as significantly increased contents of mainly proanthocyanidins and stilbenes. The results manifest the importance of intra-cultivar genetic diversity to obtain red wines with a high phenolic content, responsible of key quality aspects of the wine such as organoleptic properties, stability, complexity and health benefits. Moreover, this study exemplifies how spontaneous somatic variation can be used through grapevine clonal selection combining metabolomic analyses.

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.
