Notes
A Special Edition Collection single-origin from BOSCON Coffee Roasters, roasted in Valencia. Grown by Robinson Rivera in Cauca, Colombia at 1,960 MASL, this is a Geisha given a natural anaerobic ferment and roasted for filter — a delicate, aromatic variety paired with an expressive process.
Expect a fruit-forward, layered cup: grape and blueberry up front, cocoa and warm spice underneath, finishing with a clean black-tea-like astringency. The Geisha gives it a tea-like, floral lift that the anaerobic ferment amplifies into riper, winey fruit.
Tuned to light-roast defaults but pulled cooler and leaner than usual: fermentation flavours from an anaerobic natural turn harsh and boozy at high temperatures, and Geisha’s delicate aromatics scorch easily. A wide, warm bloom develops the residual fruit sugars, while constant 93°C pulses and a slightly lean 1:16.5 ratio keep the cup clean enough to let the florals and black-tea finish show.
