The Mediterranean climate has been traditionally favorable for winemaking and irrigation practice has been historically avoided and even forbidden, but current productive scenarios are suffering radical changes because of global warming. Therefore, seeking sustainable approaches to improve water availability is key to obtaining high-quality wines and maintain its style, without affecting yields. <i>Methods and Results</i>. Here, we aim to evaluate the effect of irrigation in Merlot vineyards, on grapes production and quality, and also on wine acceptability. Field-grown grapevines from cv. “Merlot” were subjected to two different water supplies in the field: (i) nonirrigated plants and (ii) irrigated plants with 50% of crop evapotranspiration, from veraison to commercial harvest. We assessed water stress markers such as leaf relative water content, leaf hydration, and the maximum efficiency of photosystem II photochemistry, as well as grape and wine quality parameters, wine acceptability, and preference with a panel composed of 100 participants. Furthermore, we performed a systematic review study for comparison, including 9 published reports on Merlot grapevines subjected to different water regimes, oriented to improve irrigation decisions, yield, and/or quality. Results showed that half water supply on grapevines not only induced an increase in the volume and weight of grapes, but the resulting wines had a lower total acidity and showed more desirable chromatic properties, increasing colour intensity and hue, and decreasing brightness. Sensory analysis revealed that 63% of the untrained panel preferred wines from the irrigation treatment. Integrating previously reported data, it is observed that water scarcity is favorable for quality only when compared with fully irrigated vineyards. <i>Conclusions</i>. It is concluded that a half irrigation can be enough to improve grape quality under Mediterranean conditions, without affecting yield components and enhancing sensory characteristics that can improve wine acceptance by consumers. Water management approaches to sustainably provide this extra amount of water to irrigate field-grown grapevines under the current context of climate change are discussed. <i>Significance of the Study.</i> The present study’s findings provide valuable information regarding water management in Mediterranean vineyards and its effects on the suitability of these areas to maintain high-quality wine production.</p>\u0000 </div>","PeriodicalId":8582,"journal":{"name":"Australian Journal of Grape and Wine Research","volume":"2024 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/5001343","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142174292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to investigate whether different pruning styles during the first years of vineyard training affect grapevine development.

In general, the RESP style increased the vegetative development compared to WIN and AGGR styles over the years and produced a higher yield in the first production year, although the intensity of the effect was not the same in the two vineyards considered.

Copigmentation can be responsible for almost half of the colour observed in young red wines. It has been reported that flavonols are the most effective wine copigments, but studies on the influence of the structure of these copigments on the magnitude of copigmentation are scarce. However, flavonol profiles change with grape variety and can condition the colour of the resulting wines. In addition, mannoproteins (MPs) have been reported to interact with flavonoids, which, consequently, might affect the flavonol-anthocyanin interaction. The objective of the present study was to evaluate the ability of five grape flavonols (isorhamnetin, kaempferol, quercetin, syringetin, and myricetin 3-<i>O</i>-glucosides: I-3-glc, K-3-glc, Q-3-glc, S-3-glc, and My-3-glc) by conventional spectrophotometric measurements and CIELAB analysis to copigment with malvidin 3-<i>O</i>-glucoside (mv-3-glc) in the absence or presence of five different MPs (binary and ternary model systems). Among the tested flavonols, I-3-glc was the most effective copigment, whereas K-3-glc was the least one. S-3-glc and Q-3-glc showed intermediate effectiveness, but that of S-3-glc was closer to I-3-glc and that of Q-3-glc to K-3-glc. These results point out that the presence of methoxyl groups in the B-ring of the flavonol increases copigmentation magnitude. The participation of My-3-glc in copigmentation interactions seemed to be hindered by its colloidal instability. Regarding the tested MPs, they did not provoke a direct copigmentation effect, but were able to modify the magnitude of the interaction between the flavonols and the anthocyanin and, in some cases, the colloidal behaviour of coloured aggregates formed over time. Finally, the results of the additional HPLC-DAD analyses point to a greater protection of the anthocyanin against degradation in the model systems where the magnitude of copigmentation was greater.</p>\u0000 </div>","PeriodicalId":8582,"journal":{"name":"Australian Journal of Grape and Wine Research","volume":"2024 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/6822967","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142152267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rootstocks are widely used in the viticulture industry to manage biotic stress, particularly the infestation of phylloxera, and to improve tolerance to abiotic stress. Grafting grapevines to rootstocks affects the berry quality and may influence the wine composition. This project investigated the impacts of 14 different rootstocks on the berry and wine chemical properties, phenolic profile, and volatile profile of grafted &lt;i&gt;Vitis vinifera&lt;/i&gt; L. cv Pinot noir MV6. &lt;i&gt;Methods and Results&lt;/i&gt;.

Berries were collected at harvest in the 2020 and 2021 vintages for small-scale winemaking. The pH, titratable acidity, phenolic content, and antioxidant activity of both the berries and wine were measured using conventional chemical analysis. The phenolic composition of the wine over the two vintages was identified and quantified by high-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (HPLC-QTOF-MS/MS) and HPLC with diode-array detection (HPLC-DAD). The volatile composition was measured by headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS). Grafting Pinot noir onto 3309C caused a reduction in the berry and wine pH without affecting the titratable acid. Several rootstocks, such as 1103 Paulsen, SO4, Schwarzmann, and 5C Teleki, reduced the total phenolic content (TPC) in both the berries and wine of Pinot noir. Conversely, Merbein 5489 increased the berry and wine TPC by 15% and 63%, respectively, compared to ungrafted Pinot noir MV6. A similar tendency was also found in the condensed tannin content (CTC), where Merbein 5489 increased the berry and wine CTC by 35% and 112%, respectively, compared to ungrafted vines. Several rootstocks, such as 3309C and Merbein 6262, increased the wine anthocyanin content (especially malvidin 3-O-glucoside), which may contribute to enhanced colour intensity. The concentrations of several ethyl ester compounds in wine responsible for the fruity aroma, including ethyl hexanoate, ethyl octanoate, and ethyl butanoate, were significantly higher in scions grafted to Schwarzmann, 3309C, Merbein 5489, and C29, compared to scions grafted to 101-14 Mgt, 1103 Paulsen, and ungrafted vines. This suggests that rootstock plays an important role in altering the texture and flavour of Pinot noir wine. &lt;i&gt;Conclusions&lt;/i&gt;.

Bentonite fining is commonly used in white wine production, which can lead to the loss of wine volume and aroma compounds. Many factors influence the efficacy of bentonite fining. The effect of pH adjustment and timing of bentonite addition were studied for their combined effects on Sauvignon Blanc wine protein haze formation and bentonite requirement at microscale and commercial scale. <i>Methods and Results</i>. Three bentonite addition timings were conducted on a juice pH adjustment trial: before fermentation, during fermentation, and after fermentation. The hot and cold test was utilized to determine the bentonite requirement for protein stabilization. Wine proteins were analyzed using a modified Coomassie brilliant blue (CBB) assay, lithium dodecyl sulphate polyacrylamide gel electrophoresis (LDS-PAGE), and sodium dodecyl sulphate capillary gel electrophoresis (SDS-CGE). Lower juice pH (2.80 and 3.00) resulted in sluggish fermentation, whereas the presence or absence of bentonite during fermentation showed similar fermentation kinetics at each pH. The presence of bentonite remaining in contact with ferment improved the completion of fermentation for the most sluggish ferment (pH 2.80). Commercial wine made from same batch of juice was adjusted to different pH values, and low-pH wines had a lower wine protein content and an increasing protein adsorption efficiency of bentonite fining, leading to lower bentonite requirement. <i>Conclusions</i>. Bentonite addition during fermentation was the most efficient in protein removal but fining after fermentation required the least overall bentonite dosage. The different fermentation scales (i.e., microscale versus commercial scale) slightly affected wine protein contents but not molecular weight (MW) profiles. Protein contents and MW profiles in stabilized wines were affected by the original juice pH with more complex patterns from high-pH juice. <i>Significance of the Study</i>.

Rootstocks are widely utilised in viticulture industry to prevent the infestation of phylloxera, but they may affect the growth and performance of the scion. This project investigated the impacts of 14 different rootstocks on the phenological, physiological, and nutritional performance of the scion using &lt;i&gt;Vitis vinifera&lt;/i&gt; L. cv. Pinot noir MV6. &lt;i&gt;Methods and Results&lt;/i&gt;. Two commercial vineyards located in the Mornington Peninsula wine region of Victoria, Australia, reflect two types of mesoclimate. At both vineyards, the scions of &lt;i&gt;V. vinifera&lt;/i&gt; L. cv. Pinot noir clone MV6 were grafted onto 14 rootstocks including 101-14 Millardet et de Grasset (101-14 Mgt), 1103 Paulsen, SO4, 110 Richter, Schwarzmann, 5C Teleki, 3309C, Merbein 5489, Merbein 6262, Merbein 5512, C20, C29, C113, and C114, with own roots acting as a control group. Anthesis time, veraison time, pruning mass, external leaf area index (LAI), plant hormone, and petiole nutrients were measured over three growing seasons from 2018 to 2021. Most rootstocks showed earlier anthesis compared to own roots at both vineyards. Rootstocks 110 Richter and Merbein 5512 had a 40% reduction in the leaf area index and more than 60% reduction in pruning mass compared to the control group at the Robinson Vineyard. Notably, the pruning mass of grafted vines was positively correlated with the concentration of indole-3-acetic acid in roots and salicylic acid in leaves in the present study. Rootstocks demonstrated a clear influence on the nutrient status of the grafted vines. All rootstocks, especially 3309C, C113, and C114, inhibited the accumulation of phosphorus in petioles compared to ungrafted vines. Rootstocks 3309C and C20 increased the potassium content in the petioles of grafted scions by 15% and 31%, respectively, while Merbein 5489 and Merbein 5512 reduced potassium content in petiole by 54% and 48%, respectively, compared to ungrafted vines at both vineyards during the three growing seasons. &lt;i&gt;Conclusions&lt;/i&gt;. Grafting Pinot noir onto the observed rootstocks in this study affected the phenological progress, physiological performance, and petiole nutrient status. Rootstocks 101-14 Mgt and Schwarzmann showed a similar progress of anthesis to own-rooted Pinot noir, slightly earlier progress of veraison, limited impact on canopy density and pruning mass, and no deficiency of nutrients in the petiole. Thus, these two rootstocks are considered vigorous options for Pinot noir MV6 in cool climates. The performance of Pinot noir grafted to C-series rootstocks (C20, C29, C113, and C114) needs further evaluation due to their younger age in both vineyards. &lt;i&gt;Significance of the Study&lt;/i&gt;. The present study provided results reflecting the impacts of grapevine rootstocks on Pinot noir scion performance, which support rootstock selection for Pinot noir. The results of this study provided guidance to vignerons in selecting suitable rootstock to manage ","PeriodicalId":8582,"journal":{"name":"Australian Journal of Grape and Wine Research","volume":"2024 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/5655916","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141326571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The “Superior Seedless” bunches were preserved for 90 days at 4 ± 1°C and 98 ± 2 relative humidity%. The “Superior Seedless” bunch response under cold storage was shown to be influenced by the rootstocks. According to the study, bunches picked from “Superior Seedless” that were grown on the “1103 Paulson” rootstocks performed better in antioxidant enzyme activities (AEAs) than bunches obtained from other rootstocks. Furthermore, during cold storage, the rates of H<sub>2</sub>O<sub>2</sub> and O<sub>2</sub><sup>−</sup>generation decreased more rapidly. However, combined with a low electrolyte leakage percentage (EL%) and malondialdehyde (MDA) accumulation, the 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenger concentration increased during the cold storage period. Furthermore, while berry quality traits were harvested from “Superior Seedless” grafted onto “1103 Paulson” rootstock, they were improved compared to other rootstocks. The molecular docking technique is performed to evaluate the binding affinity of antioxidant enzymes with a group of intracellular ligands, including DPPH, MDA, ascorbic acid, and tartaric acid, which show great results with respect to the DPPH compound. Following these findings, it can be concluded that the influence of rootstocks on “Superior Seedless” bunch responses to low cold storage represents a novel potential natural effect of rootstocks on responding bunches of “Superior Seedless” to low cold storage.</p>\u0000 </div>","PeriodicalId":8582,"journal":{"name":"Australian Journal of Grape and Wine Research","volume":"2024 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/4462702","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141286896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
