Blind Assessment

Sweet-savory, richly wood-framed. Date, spice box, fresh-cut fir, cocoa powder, rhododendron in aroma and cup. Sweetly savory in structure with round, gentle acidity; crisp, satiny mouthfeel. The finish is characterized by dried fruit and mixed baking spices animating fresh-cut aromatic wood.

Notes

This coffee earned the fourth-highest rating in a cupping of Hawai’i-grown coffees for Coffee Review’s May 2019 tasting report. Mamo is a big-beaned hybrid of the rare Maragogipe and Mokka varieties of Arabica, developed over the last 20 years in Kona on the Big Island of Hawai’i under the leadership of Hawai’i-based scientist Chifumi Nagai. Greenwell Farms is one of the oldest coffee farms and mills in Kona, still owned and operated on a daily basis by Tom Greenwell, a direct descendent of the founders. Greenwell Estate Private Reserve designates coffee grown on the Greenwell farm itself. Other Greenwell coffees are milled by Greenwell but grown on a variety of other Kona farms. Visit www.greenwellfarms.com or call 1-888-592-5662 for more info.

Bottom Line

An opportunity to taste one of the world’s rarest coffees, a hybrid that exemplifies the persistence and ingenuity of coffee scientists.
