    Coffee (Coffea arabica L.) Cup Quality Varies with Growing Environments in Ethiopia: Climate and Soil Perspectives
    (Editora UFLA, 2025-04-28) Woldegebriel, Abayneh Melke
    This study investigates the impact of soil composition on the quality of coffee produced across different regions of Ethiopia, with a focus on key soil nutrients— nitrogen, phosphorus, and potassium. By analyzing soil samples from Sidama, Yirgacheffe, Harrar, Jimma, and Limu, the research explores how variations in soil nutrient levels influence coffee characteristics such as flavor complexity, acidity, body, and overall quality. The results show that volcanic soils in Sidama and Yirgacheffe, with higher nitrogen and potassium levels, enhance flavor complexity and acidity, contributing to high cupping scores. In contrast, loamy and sandy soils in Jimma, Limu, and Harrar produce coffee with distinct earthy, nutty, and bold flavors, exhibiting varied acidity and body. The study highlights the critical role of soil composition in shaping the sensory profile of Ethiopian coffee and offers practical insights for farmers seeking to optimize cultivation practices. The findings also contribute to the broader understanding of terroir and its influence on coffee quality, paving the way for sustainable and innovative approaches in coffee production to meet the growing demand for high-quality specialty coffee.
