    Rakija is a strong alcoholic beverage, deeply rooted in Macedonian cultural heritage, where quality varies significantly between industrial, small-scale, and traditional home producers. This study evaluated sensory and chemical differences among three types of producers using 30 samples of rakija from grapes (10 per group). The chemical analysis included gas chromatography (GC) for volatile compounds and analytical methods for alcohol content, specific gravity, and extract. The sensory analysis was performed by a trained panel (6 assessors) following OIV 100-point scoring scale. Spearman’s rank correlation was used for statistical data analysis. Sensory results revealed greater variability in odour and taste (CV 14–29%). Isobutanol showed a significant negative correlation with quality (ρ = -0.43 to -0.46, p < 0.017), while extreme variability in esters (CV >100%, ethyl acetate up to 5,654 mg/L) and furfural (CV 383%) was detected. In contrast, the extract content positively influenced the balance (ρ = 0.43–0.50, p < 0.017) in all of the samples. Between the producer’s groups, the traditional samples had more unpleasant aromas due to improper distillation and fermentation, as confirmed by the chemical analysis results where ethyl acetate reached up to 5,654 mg/L. Routine sensory-chemical correlations can aid quality assessment, linking traditional heritage with modern distillation methods in Macedonian rakija production.

    The migration of young people from rural to urban areas poses a significant challenge to the sustainable development of rural communities in North Macedonia, leading to an aging population and diminished natural growth. This trend exacerbates socioeconomic inequalities, fostering social insecurity and the exclusion of rural youth. The far-reaching consequences of this migration influence both urban and rural landscapes across various developmental domains. To that end, this research aims to investigate the impact of main socioeconomic factors on rural youth migration. A survey of 550 rural residents aged 18-40 addressed was conducted using a tailored questionnaire. The data collection approach ensured nationwide diversity across all Macedonian planning regions, nationalities, genders and village types. Data processing involved the application of standard descriptive analysis and a binary logistic regression approach. Key findings show that factors such as gender, marital status, region, nationality, education, employment and having family agricultural holdings do not significantly impact rural youth migration. On the contrary, having children, household size, perceptions of employment opportunities, urban or rural lifestyle preferences and overall rating the quality of life in rural areas exhibit notable significance. These findings contribute to a greater understanding of the complexities surrounding rural youth migration. In conclusion, the logistic regression model serves as a powerful tool to pinpoint crucial factors influencing rural youth migration. These insights provide a solid foundation for shaping targeted policies, essential for retaining and supporting rural youth and fostering sustainable development in both urban and rural areas of North Macedonia.
