Vineyards and wineries generate seasonal, wet and compositionally variable side-streams whose safe use is constrained by rapid spoilage, contaminants, fragmented regulation and scale. This EU-focused structured narrative review synthesised 90 scientific and official sources and proposes an integrated decision framework rather than another catalogue of valorisation routes. The framework applies a non-compensatory sequence: characterise and stabilise the batch, test route-specific hazards, assign evidence-level and technology readiness, verify legal eligibility, define a safe fallback, and only then compare material flows, environmental burdens and risk-adjusted economics. Current implementation evidence is strongest for controlled composting, conventional wastewater treatment, anaerobic digestion and selected grape-seed oil, polyphenol and heat-integrated biochar operations; clinical, plant-protection and several novel-extract claims remain product- and context-specific. Illustrative ENPV cases show that high-value extraction can offer greater upside but lower robustness than compost/biochar when moisture, transport, rejection and price uncertainty are included. The framework provides an auditable basis for pilot design, regional cooperation and data collection, while explicitly requiring industrial and multi-season validation before investment or product approval.

Climate change is altering viticulture through interacting shifts in heat accumulation, water availability, radiation, soil processes, pest and pathogen pressure, wine composition, and the geography of suitable production areas. Existing reviews have treated many of these processes separately, leaving a gap in how regenerative and precision-supported adaptation can be evaluated as a coupled agroecosystem strategy. This transdisciplinary review synthesises literature on climate impacts and adaptation pathways in the vine and wine sector using a structured scoping/narrative methodology. Searches of major scientific databases and grey-literature sources were organised around grapevine physiology, soil-water dynamics, biodiversity and biosecurity, cool-climate expansion, winemaking, decision support, and economics. Evidence was screened using explicit inclusion criteria and synthesised through a thematic framework linking climate drivers to agroecosystem functions and management responses. The review shows that robust adaptation is unlikely to arise from single interventions such as irrigation, variety substitution or digital monitoring alone. The highest resilience potential is found in integrated systems that combine soil organic matter restoration, reduced tillage, cover crops, habitat diversification and vitiforestry, adaptive plant material, organic/IPM protection, precision irrigation, and AI-supported decision systems. However, the evidence base remains uneven, especially for long-term economic performance, trade-offs in dry regions, regulatory constraints on resistant cultivars, and field validation of digital tools. The paper contributes an analytical framework for regenerative, climate-resilient viticulture and identifies priority research needs for internationally relevant, economically viable and ecologically restorative wine production.

The Swedish wine culture is comparably young, and its domestic wine production is even younger, starting with the official approval by the European Union in 1999. While domestic wine production currently contributes modestly to the Swedisheconomy, the industry is experiencing notable growth. It attracts investments, gains national and international media attention, and demonstrates a strong determination to thrive. Swedish winemakers have by now shown the ability to produce highly appreciated and award-winning wines from locally grown grapes. Furthermore, recent studies conducted within the context of ongoing global warming indicate the possibility of a future, more extensive wine industry in cold climate regions, such as southern Scandinavia.In this study, we evaluate the great potential of recent emerging Swedish wine regions, which demonstrate the crucial role ofresearch in achieving industry success. Some pioneering Sweden-oriented viticulture and oenology research has been conducted, someof which is shown in this paper, indicating a possibility to diversify the used grapevine cultivars in the Swedish production. Overall, more research will be needed to advance wine farming in still relatively unknown territories. Given Sweden’s robust sustainability goals and the absence of rigid regional wine regulations, there is both a need and an opportunity for the development of locally adapted, sustainability-driven wine production methods. In this context, unique opportunities exist for practitioners and researchers to explore highly sustainable approaches, such as regenerative viticulture and multifunctional agriculture. These approaches have proven successful in other parts of the world, despite their current limited broader application.

Natural mineral soil amendments are receiving renewed attention in organic and regenerative viticulture because they can connect traditional local resources with soil remediation, soil-life restoration and climate adaptation. This partly protocol-based scoping narrative review synthesises evidence on rock powders, zeolites, clays, carbonates, gypsum, perlite, vermiculite, alginite and humic mineral materials. The review evaluates their roles in nutrient buffering, pH and cation-exchange regulation, water retention, microbial habitat formation, heavy-metal immobilisation and carbon-stabilising soil structure. It argues that mineral amendments are most effective when used with organic matter, cover crops, reduced tillage and locally adapted vineyard-floor management, rather than as stand-alone substitutes for fertilisers. Comparative tables and decision matrices are provided to link amendment choice to soil pH, texture, salinity, contamination risk, climate stress and organic certification rules. The paper highlights Central European resources, especially volcanic and organic-mineral deposits, while placing them in a global viticultural and agroecological context. The main limitations are slow and site-dependent nutrient release, potential contamination, over-mineralisation, extraction and transport impacts, cost, and uneven field evidence in vineyards. Future research should prioritise long-term replicated vineyard trials, microbial and rhizosphere indicators, life-cycle assessment and practical guidance for certified organic farms.
