Abstract:
Coffee is an important export commodity of Ethiopia that helps the country to generate foreign
exchange earnings. It is grown throughout the country including Amhara Regional State.
However, the quality of coffee grown in Amhara Region is not yet evaluated. Therefore, this study
was initiated to evaluate the quality of highland coffee varieties grown in the region. For this
purpose, eight coffee varieties are grown in Adet Agricultural Research Center and Woramit
Fruit and Vegetable Research and Training Sub-center Station which were laid down in
Randomized Complete Block Design with three replications were used. The raw and cup qualities
of coffee varieties were evaluated after harvesting and drying using traditional sun drying
processing method during the 2018 cropping season. Raw and quality parameters were evaluated
by a team of certified panelists at Jimma Agriculture Research Center while the biochemical
content of green beans was analyzed in food science and nutrition laboratory of Ethiopian
Institute of Agricultural Research, Addis Ababa. The results depicted significant variations in
some of the coffee physical parameters including fruit length and fruit thickness and biochemical
contents including trigonelline, chlorogenic acid and caffeine of green coffee beans in both
locations and coffee varieties as well as across the locations. On the other hand, cup quality
