Kurume is one of the varieties native to the Gedeo zone and reportedly originated from the Yirgacheffe. Collectively, coffee varieties that have naturally occurred and proliferated in Ethiopia are referred to as “regional landraces.”
“Ethiopian heirloom,” meanwhile, is the general term commonly used to identify coffee originating from Ethiopia. It covers regional landraces and Jimma Agricultural Research Center (JARC) varieties, which were developed and released to improve the productivity and livelihood of smallholder coffee farmers and boost the country's coffee industry. JARC varieties are promoted and bred because of their good quality when grown at the recommended elevations, resistance to or tolerance of adverse elements, and adaptability to diverse environments. There are 40+ JARC varieties comprised mostly of pure line selections and a handful of hybrids.
Ethiopian heirlooms are popularly observed to express archetypal fruity and floral qualities and a complex character.
Cultivated by Banko Gotiti farmers in modest parcels of land near their homestead without the use of non-natural inputs, Kurume and such other heirlooms that grow in close proximity are considered to be “garden coffees” that are organic by default.
The properly ripe cherries are carefully hand-picked by the farmers and delivered to conveniently located collection points, where flotation is done to spot and remove overripe, underripe, and damaged cherries. EDN employees then do a further visual assessment to ensure only the cherries at optimum ripeness proceed to the anaerobic fermentation phase, which ensues in pressurized and oxygen-free containers.
Throughout fermentation, there is strict monitoring and control to ensure the necessary sugar content, temperature, and pressure levels are met and maintained, and oxygen is consistently absent, to achieve the desired cup profile.
After 10 to 12 days in the anaerobic fermentation phase, the cherries are transferred from the fermentation tanks to the drying beds, which had been designed to allow for proper air circulation. Throughout the drying phase, which could last from 15 to 20 days until the target moisture level of 11% is reached, the cherries are periodically churned to achieve the required degree of fermentation.
Had this micro-lot undergone a washed process, the flavor profile would have been directed towards heady florals and herbally tinged bright citruses. Through the natural anaerobic process, however, the cup’s character turned towards the heightened, fragrant, and sticky sweetness of tropical fruits balanced by a muted acidity.
