This coffee has been like a breath of fresh air! I've continued on my Ethiopian coffee kick, but this flavor profile has been unique compared to the other Ethiopian coffees I've had so far this year. For me the main flavor that rings through is a marvelous melon flavor. It reminds me of a cantaloupe mixed with a honeydew. This overall melon flavor morphs and changes as the coffee cools, and with minor ratio and flow profile adjustments. It has hints of various berry notes that come and go, which alter the taste of the melon, shifting it between the cantaloupe and honeydew scale. I personally preferred more of a cantaloupe flavor, and chased various extraction specs to further exaggerate that flavor. Nonetheless it's been yet another memorable coffee from Onyx!
