Detailed knowledge of coffee production systems enables optimization of crop management, harvesting and post-harvest techniques. In this study, coffee quality is mapped as a function of coffee variety, altitude and terrain aspect attributes. The work was performed in the Zona da Mata, Minas Gerais, Brazil.
A large range of coffee quality grades was observed for the Red Catuai variety. For the Yellow Catuai variety, no quality grades lower than 70 were observed. Regarding the terrain aspect, samples from the southeast-facing slope (SEFS) and the northwest-facing slope (NWFS) exhibited distinct behaviors. The SEFS samples had a greater range of quality grades than did the NWFS samples. The highest grade was obtained from an NWFS point. The lowest quality values and the largest range of grades were observed at lower altitudes. The extracts from the highest-altitude samples did not produce any low-quality coffee.
The production site's position and altitude are the primary variables that influenced the coffee quality. The study area has micro-regions with grades ranging from 80 to 94. These areas have the potential for producing specialty coffees. © 2015 Society of Chemical Industry.
详细了解咖啡生产系统有助于优化作物管理、收获及收获后处理技术。在本研究中，咖啡品质被绘制成咖啡品种、海拔和地形方位属性的函数。该研究在巴西米纳斯吉拉斯州的马塔区进行。
观察到红卡杜艾品种的咖啡品质等级范围很大。对于黄卡杜艾品种，未观察到低于70的品质等级。关于地形方位，来自东南坡（SEFS）和西北坡（NWFS）的样本表现出不同的特性。SEFS样本的品质等级范围比NWFS样本更大。最高等级来自NWFS的一个点。在较低海拔处观察到最低品质值和最大等级范围。最高海拔样本的提取物未产生任何低品质咖啡。
生产地点的位置和海拔是影响咖啡品质的主要变量。研究区域有品质等级从80到94的微区域。这些区域有生产特色咖啡的潜力。©2015化学工业协会。
