The deformation pattern in the offshore Sumatra indicates that the Mentawai fault partly accommodates motion due to oblique subduction and suggests local interaction of the Investigator Fracture Zone near the equator. While seismic slip rates match well with the geological or GPS derived slip rates between 0° and 2°S along SFZ, the values are much lower for the fault segments north of equator. In fact, we sometimes find that over-picked beautiful polished coffees are sometimes bland in the cup.Crustal deformation rates (1900-2000) estimated for the Sumatra-Java arc region highlight (i) large variations in dextral shear motion (seismic slip) from 1 mm/yr to 29 mm/yr along the Sumatran Fault Zone (SFZ), (ii) dominantly compression with deformation velocities as high as 19 mm/yr near the equator along offshore Sumatra fore-arc and, (iii) dominance of compression (average 19 mm/yr) in the western part of offshore Java fore-arc that gradually changes to extension (average 3 mm/yr) towards east. Since Sumatran's are dry processed and often laid out to dry on the dirt in small villages, sorting the coffee is essential to take out the sticks and stones that the beans inevitably acquire, but triple picking does not necessarily improve the quality of cup. Sumatran coffees are hand sorted, and come in single-picked, double- picked, and even triple-picked lots. Quality in the cup is what matters, or should matter, not mere appearance of beans. This is not a problem, however, or a sign of bad beans.
Sometime the beans will look uneven and funky green. There is a tendency to over roast Sumatrans (along with other dry processed wild coffees) as they do not show much roast color, and roast unevenly. Sumatran coffee is a beautiful deep blue-green color with the appearance of jade. This is where cupping Sumatran after Sumatran pays off Big!) Look for notes of black licorice, cedar, dark chocolate, vanilla, and mustiness. We cup Sumatran after Sumatran to find that earthy, deep, complex, full-bodied coffee that exhibits low-acidity smoothness and a touch of forest floor funk. Sumatran coffees capture the wild jungle essence of this tropical Indonesian island.
