Blind Assessment

High-toned, arrestingly floral. Wisteria, lychee, white peach, jasmine and cocoa nib in aroma and cup. Bright, delicately juicy acidity; plush, syrupy mouthfeel. The finish is elegant and lingering, centering wisteria and white peach with a cocoa nib throughline.

Notes

Produced at Finca Wallachia, a member of Cooperativa Agraria Cafetalera Valle de Incahuasi (CACVI), entirely of the SL-09 variety of Arabica, and processed by the washed method (fruit skin and pulp removed before drying). Imported by Vela Ethan International Co., Ltd. GK Coffee is a nano-roastery in Yilan, Taiwan, that offers both retail and wholesale coffee. For more information, visit www.gkcoffee.com.tw or email gkcoffee2015@gmail.com.

Bottom Line

Often referred to as the “Inca Geisha,” this Peru SL-09 is richly floral, deeply fruity, and complexly layered throughout the profile — one of the most floral-driven coffees in memory.
