Cider quality is strongly influenced by both the apple raw material and the fermentation microbiota, yet systematic data on yeast–cultivar interactions under Nordic conditions remains limited. In this study, we conducted a screening experiment to assess how combinations of eight commercial Saccharomyces cerevisiae strains and five apple cultivars shape the chemical and sensory characteristics of cider. Single‑cultivar juices were fermented with each of the eight S. cerevisiae strains under standardized conditions to isolate the respective contributions of yeast strain and cultivar. Chemical composition was characterised by analyses of key fermentation parameters and volatile aroma compounds, while sensory quality was evaluated by a trained panel focusing on aroma and flavour profile. Both yeast strain and apple cultivar exerted marked effects on cider composition and sensory expression, with clear yeast–cultivar interaction patterns. Certain strains enhanced cultivar‑specific aroma characteristics, while others contributed more strongly to fermentation‑derived notes and mouthfeel. Differences in volatile composition were closely associated with sensory outcomes. This screening highlights the importance of tailoring yeast selection to the apple cultivar in order to optimize cider style and quality. The findings provide a basis for targeted strain choice and the development of differentiated cider products, particularly relevant for cool climate and emerging cider regions

Phosphorus is a critical resource for agriculture, but standard soil tests often fail to measure the dynamic rate at which it becomes available to crops, often leading farmers to overuse fertilizer and increase pollution risks. While the advanced diffusive gradients in thin films technology is excellent at measuring this dynamic phosphorus supply in soil, it is expensive and labor-intensive. We set out to discover if a combination of common, low-cost analyses could predict how much phosphorus plants absorb just as effectively as the advanced technology. Our research confirmed that the advanced dynamic phosphorus measurement was the single best predictor of plant phosphorus uptake. However, our key finding was that combining three simple measurements: extractable phosphorus, extractable aluminum, and soil organic carbon, predicted plant uptake and crop yield with equal or slightly better accuracy. This proves that agricultural stakeholders can use these existing, affordable labor
