The Decaf Cadefihuila Medium arrives at 90°C — a 4°C total reduction from baseline split between medium roast (-2°C) and natural processing (-2°C). The grind sits 15μm coarser than baseline, reflecting natural processing's effect on cellular structure without the -40μm light-roast solubility penalty the light version requires. Medium roast has degraded enough CGAs that extraction is no longer fighting against light roast's extraction resistance — instead the goal is maximizing the dark chocolate, almond, and caramel development that medium roasting built through Maillard and caramelization reactions. The Chemex's thick paper filter strips the natural-process oils, letting those compound types express with clarity. At 1,600m, these Castillo and Caturra grounds are denser than Cerrado Bourbon but the medium roast has reduced that density relative to the light version.
Decaf Cadefihuila Medium, Colombia
The V60 recipe for this medium-roast Colombian natural mirrors the Chemex parameters — 90°C, +15μm grind, 1:15.5–1:16.5 ratio — because both are paper-filter pour-overs where the light-natural extraction adjustments aren't needed. Without those adjustments, the recipe treats this as a medium-solubility natural bean where the primary changes are temperature moderation (not aggressive reduction) and a slightly coarser grind to prevent the natural-processing characteristics from creating too much flow resistance. The paper filter strips natural-process oils that would otherwise amplify heaviness over the dark chocolate and almond clarity. At 2:30–3:30 total brew time, the V60's fast drain means the grind calibration matters: too coarse and extraction is insufficient; too fine and the brew stalls, risking over-extraction of the outer layer of grounds.
Troubleshooting
The Kalita Wave recipe for this medium natural Colombian runs identical deltas to the V60: 90°C, +15μm grind, slightly wider ratio (1:16.5–1:17.5). The meaningful difference between the Wave and V60 for this bean is the brewer geometry — the flat bed's three-hole drain creates more uniform water distribution across the grounds than the V60's single large drain hole. For a medium-roast natural Colombian where the goal is extracting the full dark chocolate-to-caramel flavor arc without sourness on one end or bitterness on the other, evenness of extraction matters more than brew rate. The Wave's characteristic balance — neither the brightest nor the fullest method — is well-matched to this bean's profile: medium-roast Maillard sweetness doesn't need the maximum clarity of Chemex or the maximum body of French press.
Troubleshooting
The AeroPress for this medium natural Colombian drops to 81°C — a substantial reduction from filter brew temperatures suited for this roast level. No special extraction adjustments are needed here because medium roast has already increased solubility sufficiently; the bean doesn't need the elevated temperature the light version requires. At 81°C under AeroPress pressure, extraction is still efficient because the pressurized press compensates for lower thermal activation. The natural-process fermentation character adds complexity to the concentrated 1:13 ratio, and the paper filter clarifies the dark chocolate and almond notes from the medium-roast Maillard development. The +15μm coarser grind prevents puck resistance from becoming unmanageable during pressing, which addresses the same natural-processing structural consideration as the pour-over methods.
Troubleshooting
The Clever Dripper applies the same logic for this medium Colombian natural as it does for the Brazilian medium natural: immersion builds body from the Maillard-rich medium roast, and paper filtration clarifies the natural-process oils. At 90°C for 3–4 minutes, the sealed immersion steep gives the dark chocolate, almond, and caramel compounds — all products of medium-roast Maillard and caramelization reactions — full time to dissolve into solution before the drain opens. The +15μm grind is consistent across all non-light-roast methods for this bean: natural processing's cellular structure differences call for slightly coarser grind versus washed coffees to prevent over-packing. The 1:16 ratio produces a balanced cup where the Clever's characteristic body sits slightly above pour-over methods but well below French press.
Troubleshooting
Espresso with this medium-roast Colombian natural decaf scores 77/100, and the structural reasoning is straightforward: natural processing's fermentation volatiles amplify under pressure in ways that are harder to predict than washed coffees. The recipe runs 89°C (1°C cooler than pour-over methods, accounting for both roast level and processing) and the +15μm coarser grind applies at the espresso scale too, though at 265μm the absolute change is proportionally smaller than at pour-over grind sizes. The dark chocolate and caramel flavor profile of the medium roast is well-suited to espresso concentration — these are compounds that intensify without becoming harsh. Almond note intensity typically amplifies at espresso TDS, which is an asset here.
Troubleshooting
The moka pot scores 68/100 for this bean — same as the Brazilian medium natural, and for the same reason: metal mesh passes natural-process oils that compete with the cup's flavor clarity. Where the Brazilian Bourbon's natural processing generates fermentation-derived fruit character, this Colombian natural's medium roast builds Maillard dark chocolate and almond notes that the oils can amplify into heaviness. The 96°C base water follows the same logic as the Brazilian medium: at moka pot's lower operating pressure, extraction temperature at the basket is below water temperature, so starting hot compensates. The +15μm grind ensures the basket doesn't over-compact with steam pressure. The 68/100 score is not a disqualification — it means pour-over methods will express the dark chocolate and caramel more clearly, but moka pot delivers a rich, oil-inclusive cup.
Troubleshooting
French press at 66/100 follows the metal-filter pattern: natural-process oils pass freely through the mesh, and for a medium-roast Colombian where the goal is dark chocolate and almond clarity, that oil passage adds perceived heaviness rather than relevant body. The recipe uses 92°C — slightly warmer than pour-over methods for this bean — because immersion's longer contact time at slightly lower temperature still reaches adequate extraction, and the warmer temperature compensates for the coarser grind (1,015μm) that French press requires to avoid sediment. The 4–8 minute steep window is generously wide: medium-roast Colombian at 1,600m doesn't need the maximum 8 minutes to extract properly, so starting at 4 minutes and extending if the cup is flat gives good control.
Troubleshooting
Cold brew scores 64/100 for this medium-roast Colombian natural — notably different from the 0/100 the light version receives. Medium roast's lower CGA content and higher solubility make cold extraction feasible in a way that light roast is not: the Maillard-built dark chocolate and caramel compounds are more soluble in cold water than the intact CGAs and higher-density structure of a light roast. Cold water's suppression of CGA hydrolysis works in this bean's favor — fewer bitter quinic acid byproducts, more of the medium-roast sweetness expressing clean. The 80g/560g concentrate ratio with 915μm grind targets 12–18 hours, allowing melanoidin extraction to develop over time. The natural-process fermentation character may partially mute in cold brew, but the dark chocolate core remains.
