Divino Niño Gesha - Wet Process - Education Lot - 2024

The V60 at 87/100 works for this Education Lot Gesha because the variety's raspberry and black tea character is aromatic rather than structural — it comes from volatile ester and Strecker degradation compounds, not from lipid-carried flavor. The V60's thinner filter passes slightly more volatile carriers than the Chemex, which on a washed 1,700m Gesha can sharpen the raspberry note's clarity. The 450um grind is 50um below default: the finer setting compensates for extraction resistance without over-dosing fines that would clog the single drain hole and cause uneven stalling. At 93C, 1C below neutral, the temperature protects Gesha's fragile aromatic compounds from thermal degradation before they can exit the bed. The result emphasizes the tea-fruity register more prominently than the Chemex's maximally clean output.

The Kalita Wave's flat-bottom uniform extraction is especially well-suited to this 1,700m Gesha's black tea and wafer cookie character. Black tea notes come from low-level Maillard development at light roast — honey-floraland similar Strecker products producing a slightly astringent, floral quality. Uneven extraction collapses this nuanced character into a single sour-bitter note. The Wave's flat bed and three holes distribute flow more evenly than a cone, protecting that fragile tea register. At 480μm grind, 93°C, and 1:16.5 ratio, the recipe is slightly leaner than the V60, reflecting the Wave's longer dwell from lower-flow holes — the extended bed contact provides marginally more body, which rounds the wafer cookie sweetness that would otherwise disappear on a thinner extraction.

The Clever Dripper bridges the Education Lot Gesha's two challenges: extraction difficulty from light roast and the need for aromatic clarity to express black tea and raspberry character. The immersion phase at 480um and 93C gives this lower-altitude 1,700m Gesha more contact time than a V60 pour-over, which matters because the bean's slightly lower density means diffusion rates are more forgiving. The paper filter then removes the oils that would muddy the tea-like Strecker degradation compounds. Unlike the French press, where oils compete with volatiles, the Clever's filtered output lets the wafer cookie sweetness register clearly. The 1:15.5 ratio is leaner than AeroPress but richer than Chemex, reflecting the Clever's middle-ground position between full immersion and drip clarity.

The AeroPress at 84C for this Education Lot Gesha creates an interesting dynamic: the lower temperature slows acid extraction relative to hot pour-over methods, which on a 1,700m lot with raspberry and black tea notes produces a more balanced cup than a hotter AeroPress would. The raspberry character in this Gesha comes partly from volatile esters that are sensitive to both heat and pressure exposure — the AeroPress at 84C with 1-2 minutes contact extracts these more gently than 93C espresso would. The 350um grind is the finest of all non-espresso methods, necessary because the lower temperature reduces the extraction rate and requires more surface area to compensate. The 1:12.5 ratio builds enough concentration that the wafer cookie sweetness registers even at lower solubility. This is the format where the Education Lot's approachable flavor profile shows most clearly.

Light-roast Gesha espresso is demanding for the same reasons as other light-roasted Geshas: dense, low-solubility beans at 9 bar require extended preinfusion and a longer ratio to extract evenly rather than channel. At 200μm, 92°C, and a 1:2.4 yield ratio, the recipe works against the Gesha's natural extraction resistance. What makes this lot distinctly challenging at espresso is the raspberry character: raspberry esters are volatile and fragile under pressure extraction at high temperature, so they survive a slower shot pulled at the lower end of 92°C better than a fast high-pressure extraction. The black tea character, which depends on balanced Maillard development, concentrates differently under espresso conditions — the pressure extracts heavier melanoidins that the light roast has not fully developed, producing thinner body than expected. Expect the shot to be more citric-raspberry than tea-like.

Moka pot at 71/100 for this 1,700m Education Lot Gesha demands Hoffmann's pre-boiled water technique to work at all. Starting with cold water means the grounds cook in rising steam before pressure builds — for a delicate light-roasted Gesha, this destroys the aromatic compounds before they can extract properly. With pre-boiled water, the 300um grind creates adequate bed resistance at 1.5 bar. At this altitude, raspberry esters and black tea Strecker degradation products survive moka pot extraction better than on higher-altitude varieties because the 1,700m Gesha's slightly lower density extracts more readily, compensating for the moka's lower pressure. The 1:9.5 ratio concentrates the output enough that the wafer cookie sweetness registers, though the metal filter passes oils that will add body the Chemex would strip.

French press at 67/100 is the lowest hot-brew match for this Education Lot Gesha, and the mismatch is mechanical: unfiltered oils and fines obscure the variety's most distinctive qualities. The black tea character in this lot — coming from honey-floraland Strecker degradation products — competes directly with the heavier lipid-extracted compounds that French press passes. What you get is a heavier cup where the tea-like quality flattens into a generically roasty body. The 950um grind and 95C temperature push extraction as hard as possible given the light roast's low solubility, and the 1:14.5 ratio reflects the immersion format's need for concentration. This is still a usable cup — the raspberry ester character survives French press — but the black tea precision that defines this lot's character is diluted significantly.
