Climate change is having a profound impact on Portugal’s wine industry, a key part of its cultural and economic heritage. Rising temperatures, shifting rainfall patterns, and more frequent extreme weather events are creating challenges for traditional wine regions like Douro, Alentejo, and Dão. Warmer temperatures are accelerating grape ripening, leading to wines with higher alcohol content and lower acidity, while unpredictable rainfall causes water stress and increases the risk of disease. Extreme weather, such as heatwaves and hailstorms, can devastate vineyards, particularly in regions vulnerable to soil erosion. To adapt, winemakers are experimenting with heat- and drought-resistant grape varieties and implementing new vineyard management practices, but the costs of these changes are significant, especially for smaller producers. As the climate continues to shift, the quality and consistency of Portuguese wines are at risk, with potential economic and cultural consequences.
Viticulture and the European Union’s Common Agricultural Policy (CAP): Historical overview, current situation and future perspective
The paper emphasizes the importance of disseminating agroecological knowledge and implementing nature-based strategies to ensure the successful application of the CAP reforms. It calls for a collective awareness and effort from all societal sectors, including producers, consumers, and policymakers, to embrace environmental protection measures in agriculture. The paper also stresses the need to communicate effectively the benefits of biodiversity conservation and natural soil processes to accelerate the adaptation of agricultural systems to environmental challenges.
Enhancing employee wellbeing and happiness management in the wine industry
This research examines the connection between Green Human Resource Management (GHRM) and Sustainable Performance (SP) in Spanish wineries, emphasizing the mediating roles of Employee Wellbeing (EW) and Work Engagement (WE). This study is pertinent, given the growing focus on sustainability as a core business strategy. To refine the precision of the examined cause-effect relationships, variables such as the age and size of the winery and membership in a Protected Designation of Origin (PDO) are incorporated as controls. Utilizing a conceptual model informed by prior studies, this study employs structural equation modeling (PLS-SEM) to analyze data from 196 wineries collected from September 2022 to January 2023. The findings highlight a positive and significant link between GHRM practices and the SP of these wineries, with EW and WE serving as partial mediators. The significance of this study lies in its contribution to the understanding of GHRM’s benefits in enhancing SP, particularly in the Spanish wine industry, a context not extensively explored in previous research. To the best of our knowledge, this study is the first to investigate the mediating effects of EW and WE on the GHRM-SP relationship in this sector, marking a notable advancement in this field.
Management practices, and not surrounding habitats, drive bird and arthropod biodiversity within vineyards
This post is about a paper that concluded that individual management practices are more influential on vineyard biodiversity than the habitat context, overall management regime, or certification status. This study recommends that sustainability accreditation schemes focus on reducing the ecotoxicity of agrochemicals used and encourage the promotion of higher ground vegetation cover by reducing herbicide use to benefit vineyard biodiversity.
Attitudes towards natural wines among Spanish winemakers: Relationship with environmental awareness
this research pioneers in revealing the complex interplay of ecological awareness, sensory perceptions, and market understanding in shaping Spanish winemakers’ attitudes towards NWs. It underscores the need for further research to bridge the gap in consumer and producer perceptions and to address the current asymmetry of information in the wine market. The study’s limitations include its reliance on convenience sampling, suggesting a need for more comprehensive future research designs.
Application of white wine lees for promoting lactic acid bacteria growth and malolactic fermentation in wine
This study explored the potential of utilising white wine lees, a by-product of winemaking, in the industrial application of wine production. By examining the growth of wine lactic acid bacteria and their impact on the malolactic fermentation process, this study highlights the potential of using wine lees as a beneficial agent for MLF in red wines. The study also confirmed that the inclusion of white wine lees does not negatively impact the quality of wine and does not encourage the growth of spoilage microorganisms. Overall, this study proposes a sustainable recycling strategy for wine by-products in winemaking.
Enhance Wine Production Potential by Using Fresh and Dried Red Grape and Blueberry Mixtures with Different Yeast Strains for Fermentation
Our colleague Juan Martín-Gómez from Universidad de Córdoba, Spain presented a fascinating research study on the ‘Sustainability of wine production and food systems in the Mediterranean region’ at the 3rd World Science & Wine Congress. This study focused on replacing traditional sun-drying methods in Mediterranean winemaking with controlled-airflow chamber-drying. This alternative technique improves the quality, phenolic content, and antioxidant properties of red grapes and blueberries. Furthermore, the post encourages researchers to consider submitting their work to a special joint issue. Because these issues are interdisciplinary, authors are given the flexibility to choose from several participating journals based on their research scope. The options include Foods; Sustainability; IJERPH; Agriculture.
Effects of Global Warming on Grapevine Berries Phenolic Compounds—A Review
As autumn heat reaches unprecedented levels, a groundbreaking study delves into the impact of climate change on phenolic compounds in grapevine berries. These findings challenge traditional winemaking norms, emphasizing the need for tailored approaches to combat climate challenges. The study advocates for a nuanced, “single case” perspective, recognizing the diversity of grapevine environments. Standardizing treatments across different cultivars, legislations, and regions is impractical. Instead, the focus has shifted to individual vineyards, embracing the concept of terroir, where unique natural, physical, and climatic conditions influence wine characteristics. This flexible approach encourages winegrowers and consumers to appreciate each vintage’s distinctiveness. By acknowledging and adapting to climatic changes, winemaking can evolve and foster innovative techniques and novel taste experiences. Resisting the urge for uniformity might simply unlock new dimensions in the wine world.
Ancient DNA analysis of winegrape seeds reveals genetic link between two modern varieties of red and white grapes and grape varieties cultivated some 1,100 years ago
One ancient seed was found to belong to the Syriki variety, still used to make red wine in Greece and Lebanon. Since winegrapes are usually named after their place of origin, it is quite possible that the name Syriki is derived from Nahal Sorek, an important riverbed in the Judean Hills. A second seed was identified as related to the Be’er variety of white winegrapes still growing in the sands of Palmachim on Israel’s southwestern Mediterranean seashore.
Perceiving and Adapting to Climate Change: Perspectives of Tuscan Wine-Producing Agritourism Owners
It is now widely accepted that climate change is having a profound impact on the weather systems around the world. These, in turn, have a considerable effect on two important elements of the Tuscan economy: wine production and tourism. This case study sought to explore the relationship between the perception of Tuscan wine-producing agritourism owners of the potentially abstract notion of climate change and their concrete experiences as entrepreneurs. While recognizing the difficulties they face from climate change as viticulturists, as agrotourism owners they welcome the longer seasons which enable them to open in the formerly barren shoulder seasons but struggle with last-minute cancellations due to unpredictable weather in the area.
