Today's wine industry is characterized by regional differences not only in the wines themselves but also in the business models by which these wines are produced, marketed, and distributed. In Old ...World countries such as France, Spain, and Italy, small family vineyards and cooperative wineries abound. In New World regions like the United States and Australia, the industry is dominated by a handful of very large producers. This is the first book to trace the economic and historical forces that gave rise to very distinctive regional approaches to creating wine.
Varietals of Capitalismshows that politics is an omnipresent part of the economics of wine and of economic activity in general. Based on a four-year research project encompassing fieldwork in France, ...Spain, Italy, and Romania, Xabier Itçaina, Antoine Roger, and Andy Smith examine the causes and effects of a radical reform adopted at the EU level in 2008. Regulatory change politically transformed the rationale of EU support to the wine industry, from shaping the supply side to encouraging producers to adapt to the demands of a supposedly "new consumer."
To explain the adoption and impact of the reform, the authors develop an analytical framework to capture the actors-their perceptions, preferences, and interdependencies-within an industry crisscrossed by institutions located at the global, European, national, and local scales. This framework combines concepts and lessons from historical institutionalism and regulationist economics, Bourdieu's field theory, and the sociology of public policymaking. The authors reject accounts that attribute policy change simply to material determinants and "the invisible hand of the market." They emphasize the crucial importance of institutions within sectors of the economy, and propose ways to bolster constructivist approaches to political economy by linking industrial change to scientific and bureaucratic balances of power. This book's novel focus on different levels of institutional impact should prove influential in the study of the politics of industry, and more broadly within the comparative analysis of capitalism.
Fomitiporia mediterranea (Fmed) is the primary Basidiomycota species causing white rot in European vineyards affected by the Esca complex of diseases (ECD). In the last few years, an increasing ...number of studies have highlighted the importance of reconsidering the role of Fmed in ECD etiology, justifying an increase in research interest related to Fmed's biomolecular pathogenetic mechanisms. In the context of the current re-evaluation of the binary distinction (brown vs. white rot) between biomolecular decay pathways induced by Basidiomycota species, our research aims to investigate the potential for non-enzymatic mechanisms adopted by Fmed, which is typically described as a white rot fungus. Our results demonstrate how, in liquid culture reproducing nutrient restriction conditions often found in wood, Fmed can produce low molecular weight compounds, the hallmark of the non-enzymatic "chelator-mediated Fenton" (CMF) reaction, originally described for brown rot fungi. CMF reactions can redox cycle with ferric iron, generating hydrogen peroxide and ferrous iron, necessary reactants leading to hydroxyl radical (sup.*OH) production. These observations led to the conclusion that a non-enzymatic radical-generating CMF-like mechanism may be utilized by Fmed, potentially together with an enzymatic pool, to contribute to degrading wood constituents; moreover, indicating significant variability between strains.
•Stakeholder engagement in co-creation involves cognitive, emotional, and behavioural aspects.•Stakeholder engagement is driven by stakeholder-, firm-, and context-based factors.•Mechanisms that ...promote stakeholders’ interactions level co-creation processes.
Companies need to enhance corporate performance by stimulating the links between stakeholder engagement, innovation, and co-creation. Previous literature lacks a systematic and integrative conceptualisation of these factors, limiting our understanding of how to leverage stakeholders in innovation and co-creation strategies. Based on a systematic literature review (112 papers), this paper presents a discussion on the conceptualisations of stakeholder engagement, open innovation, and co-creation, compiles research gaps and further research directions, and propose a conceptual model for stakeholder engagement. The model is globally validated through a case study from 22 companies in the wine industry. Findings suggest jointly managing engagement in co-creation activities of internal and external stakeholders through several types of antecedents, accounting for engagement evolution across time. Among its limitations, this research excludes working papers under review and studies not in English. The model validation is circumscribed to ongoing co-creation processes involving internal stakeholders and distribution partners.
Background Improving the nutritional condition of grapevine in spring to regulate bloom, fruit set, and yield is among the management goals of vineyards. Methods In the present study, the early ...season spray of calcium sulfate (C; 0.00 and 2.00%), potassium sulfate (K; 0.00 and 3.00%), and agricultural grade mineral oil (V; 0.00 and 1.00%) on flower and fruit phenology, nutrient concentration, and cluster biophysical indices and yield of Sultana grapevine (Vitis vinifera L.) were investigated for two consecutive years. Results Based on the results, the spray of this nutrient combined with mineral oil significantly affected all the treatments except cluster length, berry length, and phosphorus concentration. The highest concentrations of potassium, calcium, and magnesium were obtained in the vines treated with V.sub.0K.sub.1C.sub.1, and the highest concentrations of zinc and iron were obtained only in the vines treated with mineral oil. In treatments containing mineral oil, especially in combination with the second level of calcium and potassium (V.sub.1K.sub.1C.sub.1), bloom time, berries pea-sized time, and harvest time were delayed by 3, 3, and 6 days compared with control vines. While in vines treated with a combination of the second level of potassium and calcium (V.sub.0K.sub.1C.sub.1), bloom time, berries pea-sized time, and harvest time were advanced by 5, 4, and 1.50 days, respectively, compared with control vines. Regarding the biophysical indices of the cluster, it was found that the vines treated with V.sub.1K.sub.1C.sub.1 had higher cluster weight, berry weight, fruit, and raisins yield than other treatments. Also, the highest berry quality, including total soluble solids, titratable acidity, and total phenol content, were obtained in the vines treated with V.sub.0K.sub.1C.sub.1. However, the lowest berry quality was observed in the vines treated with mineral oil. Conclusions Therefore, the combination of nutrients with mineral oil can alleviate the adverse effect of mineral oil solely on some phenological indices and berry quality-related traits in vineyards.

Grapevine trunk diseases (GTDs) attack the vine’s wood, devastating vineyards worldwide. Chile is the world’s fourth-largest wine exporter, and Cabernet Sauvignon is one of the most economically ...important red wine varieties. Botryosphaeria dieback is an important GTD, and Diplodia seriata is one of the main pathogenic species. Biocontrol studies of these pathogens are commonly carried out at different incubation times but at a single temperature. This study aimed to evaluate the biocontrol effect of Chilean PGPB and grapevine endophytic bacteria against D. seriata at different temperatures. We analyzed the biocontrol effect of Pseudomonas sp. GcR15a, Pseudomonas sp. AMCR2b and Rhodococcus sp. PU4, with three D. seriata isolates (PUCV 2120, PUCV 2142 and PUCV 2183) at 8, 22 and 35 °C. Two dual-culture antagonism methods (agar plug diffusion and double plate) were used to evaluate the in vitro effect, and an in vivo test was performed with Cabernet Sauvignon cuttings. In vitro, the greatest inhibitions were obtained using the agar plug diffusion method and at a temperature of 8 °C, where Rhodococcus sp. PU4 obtains a 65% control (average) and Pseudomonas sp. GcR15a a 57% average. At 22 °C, only strains of Pseudomonas sp. show control. At 35 °C, one Pseudomonas strain shows the highest control (38%), on average, similar to tebuconazole (33%), and then Rhodococcus sp. (30%). In vivo, a biocontrol effect is observed against two D. seriata isolates, while the PUCV 2142 proves to be more resistant to control. The biocontrol ability at low temperatures is promising for effective control in the field, where infections occur primarily in winter.
Grapevine, a crop of global economic importance, is annually affected by diseases that can compromise the quality and quantity of the harvest, producing large economic losses. Downy mildew caused by ...Plasmopara viticola (Berk. & M.A. Curtis) Berl. & de Toni is one of the most important diseases in the vineyard. To fight this pathogen, winegrowers often rely on conventional chemical fungicides or copper-based formulations, whose use is determined to be reduced by the European Commission due to their environmental consequences. Hence, alternative plant protection products (PPP) in grapevine must be considered and studied. In this context, we selected several alternative commercial products, based on basic substances (BS) or low-risk active substances (LRAS), to evaluate their suitability to deal with P. viticola. We measured the preventive activity of the products, both in vitro and in planta, as well as their toxicity against the sporangia and zoospores of the pathogen. Results showed that four commercial products were effective against the pathogen directly and preventively, being composed of approved basic substances, more concretely, chitosan, Equisetum arvense, lecithins, and Salix cortex. Among those, the products composed of lecithins and Salix cortex were the most toxic and active preventively. Therefore, these basic substances should be promoted in the vineyard as an alternative to conventional treatments in order to transition to a more sustainable viticulture.
