Blend wines made of Syrah, Marselan and Tannat, had better color and more phenolic diversity than varietal wines

Abstract

Background: Elaborating red-wines from grape cultivars with different polyphenolic profiles could improve wine color and its phenolic-dependent characteristics. Aim: the aim of this research was to study the effect of elaborating blend wines from grape-cultivars with different phenolic profiles on, copigmentation, promotion of stable pigments, color, and contents of phenolic compounds. The time of blending, before-fermentation blends of musts (BFB) or after-fermentation blends of wines (AFB) was also evaluated. Material and Methods: During 2020 vintage, blend wines were made from grapes (m/m) or wines (v/v), in proportion of 1/2-1/2 of Tannat-Marselan, Tannat-Syrah, Syrah-Marselan, and 1/3-1/3-1/3 of Tannat-Syrah-Marselan. The varietal wines (VW) were also elaborated, all by triplicate at experimental scale. Spectrophotometric analysis (including total phenols, wine color, and antioxidant capacity measurements) were performed right-after wine stabilization, and a year later together with LC-DAD-MS/MS determinations (analysis of pigments, flavonols, flavan-3-ols, hydroxycinnamic acids and stilbenes). Wines and samples of the grape skin and seed used in the experiments were also analyzed. Results: Tannat wines had pigments with low proportion of malvidin and acylated derivatives, high contents of hydroxycinnamic acids, flavan-3-ols, and relative low contents of flavonols (mainly based on myricetin). Syrah wines had high proportion of malvidin and the highest of acylated derivatives, low contents of hydroxycinnamic acids, medium concentrations of flavan-3-ols, and high contents of flavonols, particularly based on quercetin and isorhamnetin. Marselan, showed high contents of anthocyanins, with the highest proportion of malvidin, high concentrations of hydroxycinnamic acids, flavan-3-ol and flavonols, with high proportion of syringetin. Thus, each cultivar expressed its characteristic phenolic profile. Copigmentation was significantly higher in Marselan than in Syrah, and in Syrah than in Tannat wines, but the blended wines that included Tannat and Marselan had the highest proportion of copigmentation, possibly due to a better relationship between pigments and copigments like flavonols. The BFB wines had higher and more bluish color than AFB wines, mainly due to BFB wines had significant lower pH that AFB (e.g. Marselan_Tannat CI 13.93 and 12.77 in BFB and AFB respectively). The BFB wines had higher color due to polymers than BAF and VW wines. Tri-varietal blends presented a more bluish hue than bi-varietal blends, maybe because of the better balance among pigments and compigments found in the formers. The wines made BFB had higher content of phenols in the wines after a year than the expected considering the proportion of each cultivar in the blend. Blend red-wines made considering grape-cultivar phenolic characteristics may improve wine quality.

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.
