“…The average grape berry weight (0.64 g–1.6 g) and the number of seeds in the grape berry (1.08–2.03) in the variety Cabernet Sauvignon correspond to results that can be considered a varietal characteristic, bearing in mind the positive correlation with the results of other authors who dealt with this issue [ 8 , 50 , 51 , 52 ]. Similar results were recorded in the analysis of the number of grape berries in a grape cluster, which ranges from 65 to 164 [ 53 , 54 , 55 , 56 ], except for a slightly higher number of berries at the Trebinje locality during 2020. The grape berry weight of the Merlot variety is significantly influenced by production conditions, as evidenced by many literature references.…”

Viticulture is of great economic importance in the southern part of Bosnia and Herzegovina, thanks to favorable climatic conditions and a long-standing tradition of growing vines. The assortment is dominated by international varieties, as well as some autochthonous and domesticated varieties. The subject of the research is the analysis of the quality of Cabernet Sauvignon, Merlot, Vranac, and Blatina varieties at two localities in Herzegovina during the period 2020–2021. The paper examined the most important economic and technological characteristics, grape quality, and berry phenolic profile. A particularly pronounced variation of the tested characteristics during the research period was observed in the Merlot and Blatina varieties, while the Cabernet Sauvignon and Vranac varieties showed a slightly higher stability of the tested characteristics. Poorer grape quality during the research period was registered with the Blatina variety, which can be considered a varietal characteristic to some extent. The analyzed grape varieties were rich in polyphenols, and the impact of grape variety on the berry phenolic profiles was confirmed. The most abundant polyphenols in the analyzed grape samples were quercetin 3-O-glucoside and catechin gallate, followed by kaempferol 3-O-glucoside. The highest values of polyphenols were found mainly in the samples originating from Trebinje. Indigenous Balkan grape varieties (Vranac and Blatina) stood out with particularly high contents of some phenolics. Research has shown that climatic conditions have a significant influence on the most important characteristics of grapes, which are conditioned by genotypic specificities. The conditions for growing vines in the conditions of Herzegovina enable high quality in the production of grapes, especially the Cabernet Sauvignon and Vranac varieties. The autochthonous variety Blatina shows significant variations in grape quality during the test period, which was confirmed by the results of a larger number of studies in the previous period.

“… Fidelibus et al. (2006 , 2007 , and 2009 ) evaluated different varieties of Chardonnay, Merlot, and Barbera and observed that the varieties with larger berries were more susceptible to SR, as large berries often contribute to the development of tight clusters. Lisek and Lisek (2021) assessed the susceptibility to SR of 28 wine and 25 table grape cultivars with diverse geographic and genetic origins.…”

“…In the majority of these papers (n = 22), the disease was assessed by visual observations in terms of disease incidence or severity. Disease incidence was expressed as the percentage of clusters showing SR symptoms ( Duncan et al., 1995 ; Tjamos et al., 2004 ; Dimakopoulou et al., 2008 ; Calvo-Garrido et al., 2013 ; Calzarano et al., 2019 , 2020 ; Carbó et al., 2019 ; Vogel et al., 2020 ; Kenney and Hall, 2021 ; Owoyemi et al., 2022 ), as the proportion of clusters having four or more adjoining berries with SR symptoms ( Fidelibus et al., 2005 , 2006 , 2007 , 2009 ), or as the percentage of affected berries over the total number of detached berries ( Gao et al., 2020 ). Disease severity was expressed as the percentage of affected berries (i.e., berries with SR symptoms) over the total berries in a cluster ( Tjamos et al., 2004 ; Calvo-Garrido et al., 2013 ; Calzarano et al., 2019 , 2020 ; VanderWeide et al., 2020 ; Vogel et al., 2020 ; Kenney and Hall, 2021 ; Carbó et al., 2019 ), as the percentage of the cluster surface with SR symptoms ( Tjamos et al., 2004 ; Hall et al., 2018b ; Vogel et al., 2020 ; Lisek and Lisek, 2021 ; Cornelissen et al., 2022 ), or as an empirical rating ( Schena et al., 2005 ; Nigro et al., 2006 ; Huber, 2016 ; Madden et al., 2017 ; Pinto et al., 2017 ; Hall et al., 2018b ; Calderone et al., 2022 ).…”

Sour rot (SR) is one of the major diseases affecting grapevine berries, causing severe yield losses and deterioration of wine quality. SR is caused by an etiologic complex of microorganisms, including yeasts, bacteria, and filamentous fungi. This systematic review focuses on the etiology, epidemiology, and control of SR. A total of 74 papers published between 1986 and 2023 were assessed in this review. Description of disease symptoms was quite consistent across the papers, including oxidation of the grape skin, disaggregation of the internal tissues, and detachment of the rotten berries from the pedicel. The affected bunches are characterized by the smell of acetic acid and ethyl acetate that attracts fruit flies (Drosophila spp.). However, several knowledge gaps and/or inconsistencies were identified with respect to SR etiology, epidemiology, and control. Overall, 146 microorganisms were isolated from the affected berries (44.5% yeasts, 34.3% bacteria, and 21.2% filamentous fungi); however, the selected papers could not definitively clarify which species are primarily involved in the etiology of the disease. A general inconsistency was also observed in the methods used to assess the incidence and severity of SR in vineyards, making inter-study comparisons extremely challenging. Inconsistencies were also found in the methods used for pathogenicity assessment in artificial inoculation studies. Furthermore, gaps were detected in terms of SR epidemiology, with a focus on environmental conditions affecting the disease development. The SR management options are limited, and efficacy trials often result in poor, variable, and inconsistent levels of control, which might be attributed to the lack of knowledge on disease epidemiology. These knowledge gaps and inconsistencies were analyzed in this review to inform future research activities.

“…When the berry TSS reached the commercial harvest standard of ~24 Brix for SJV Cabernet Sauvignon, yield and yield components (number of clusters, average cluster weight, average berry weight, and number of berries per cluster) were determined at harvest from each vine using methods similar to those described (Fidelibus et al 2009). Mean cluster weight was calculated as the ratio of yield divided by number of clusters per grapevine.…”

Background and goalsThe hot climate in the San Joaquin Valley (SJV) makes it difficult to achieve the optimal berry color for Cabernet Sauvignon (Vitis vinifera L.), and manual cultural practices are cost prohibitive because of low price paid per ton. A field study was conducted to investigate the interactive effects of irrigation and mechanical fruit-zone leaf removal on grapevine physiology, yield components, and berry anthocyanins of Cabernet Sauvignon grapevines grown in the SJV. Conclusions and significanceBloom leaf removal is more effective than RDI at improving berry total anthocyanin concentration without adversely affecting yield. Given the significant reduction on yield from RDI and the low economic return per ton of fruit in the SJV, bloom mechanical leaf removal coupled with SDI should be the preferred practice.
