The global wine sector faces climatic instability, changing consumption patterns and demand for differentiated products linked to origin, authenticity and experience. In this context, winter wines can be conceptualized as an emerging and still-consolidating wine category based on double pruning, a vineyard management strategy that shifts grape ripening and harvest to autumn–winter. This narrative and critical review integrates evidence from viticulture, enology, sensory science, microbiology, consumer research, wine tourism and market studies to examine winter wines not only as a technical outcome of double pruning, but also as an emerging wine category shaped by processes of formation, potential consolidation and market positioning. The review argues that winter wines are shaped by the interaction among winter ripening, cultivar adaptation, rootstock, canopy management, harvest timing and winemaking. It also proposes human-mediated terroir as a useful conceptual framework, because pruning reorganizes the temporal conditions through which climate, soil, biological material and human decisions influence wine identity. The Brazilian experience, particularly the protected geographical indication Vinhos de Inverno Sul de Minas, illustrates how technical innovation can be linked to geographical origin, collective reputation and symbolic value. Nevertheless, the category requires multi-region and multi-vintage studies, sensory characterization, consumer research and clearer communication strategies. Winter wines may offer a relevant model of innovation, climate adaptation and regional differentiation in contemporary wine markets.

This study aims to identify and analyze the market practices adopted by the Agricultural Research Company of Minas Gerais (Epamig) to highlight actions that contribute to the market making of coffee in Minas Gerais. The qualitative research, based on a case study, identified the exchange, normalizing, representational, and structuring practices implemented by Epamig through the commercialization of improved seeds, compliance with regulations, organization of events, and strategic partnerships. The results demonstrate that these practices are fundamental to the modernization and sustainability of coffee farming. However, interviews with researchers and coffee producers revealed challenges such as the lack of a continuous feedback program, systematic technical assistance, and limitations in disseminating technologies, indicating the need for improvements in these areas.

As garantias de serviço (SG) em marketplaces digitais desempenham papel central na redução do risco percebido e na construção de confiança, especialmente em ambientes marcados por assimetria de informação. Apesar de sua relevância estratégica, persistem lacunas quanto à compreensão de como atributos operacionais das garantias, como clareza, facilidade de acionamento e incondicionalidade, se associam à satisfação do consumidor. Assim, este estudo tem como objetivo descrever e examinar associações entre a percepção das SG do Mercado Livre e a satisfação do consumidor no contexto de marketplaces digitais. Adotou-se abordagem quantitativa, descritiva e transversal, com amostra não probabilística de 378 respondentes. As análises envolveram correlação de Spearman, modelagem de redes (qgraph), escalonamento multidimensional e boxplots. Os resultados indicam avaliações predominantemente positivas de satisfação e das garantias, com associações consistentes entre os construtos. Observou-se maior dispersão em itens relacionados ao estorno, sugerindo oportunidades de aprimoramento na clareza processual e na comunicação desses itens.
