Colombia, Carmen Montoya

The grind lands at 495μm — 5μm finer than V60 default — balancing two forces: the anaerobic washed processing backs the grind off slightly because the fermentation compounds extract readily, while the Chiroso variety's delicate aromatic character benefits from a touch more surface contact. At 89°C, temperature drops a full 5°C below default — the medium roast, anaerobic processing, and Chiroso's fragile aromatics all contribute to pulling temperature down significantly. The V60's faster-flowing outlet puts more pressure on your pour technique at this low temperature. Pour slowly and consistently to keep the slurry temperature stable — Gagné measured slurry temps running 5-15°C below kettle temperature in most pour-over setups, so a ceramic V60 at 89°C would drop the actual extraction zone dangerously close to under-extraction. A plastic V60 is the better choice here: its lower heat capacity keeps slurry temperature more stable, protecting the darjeeling floral and orange notes.

The flat-bottom geometry of the Kalita Wave is worth understanding for this bean. Flat-bottom drippers consistently produce more uniform extraction than conical ones — water exits from three small holes across the full bed width rather than funneling to a single point, which reduces bypassing and improves evenness. For Carmen Montoya's anaerobic washed profile, where the raw sugar and darjeeling notes occupy a fairly narrow extraction window between sour and thin, that uniformity matters. The grind at 525μm is slightly coarser than the V60 (495μm), which gives the Wave's slower drainage more flow resistance to work with. Temperature is kept at 89°C for the same reason as all paper-filter methods here: chiroso's volatile aromatics are the defining character and they're thermally fragile.

The AeroPress recipe drops to 80°C — 9°C below the pour-over methods' 89°C — and that's the single most important parameter on this brewer. AeroPress's short brew time (1-2 minutes) and full immersion mean it can achieve adequate yield at temperatures where a V60 would dramatically underextract. At 80°C, the chiroso variety's heat-fragile esters survive intact: the darjeeling character in particular is driven by aromatic compounds that resemble those found in Darjeeling tea — muscat-like, slightly fermented, temperature-sensitive. The finer grind (395μm vs. 495μm for V60) compensates for the lower temperature by increasing surface area. Paper AeroPress filter maintains the oil-free clarity that suits this bean's anaerobic washed processing. Pressing in 1-2 minutes keeps extraction clean before bitter compounds follow.

The Clever Dripper combines immersion steeping with paper-filter drainage, which gives it a useful property for this bean: the coffee grounds are submerged in water for the full 3-4 minutes before the valve opens, meaning extraction happens at a more consistent ratio than a continuous-pour method. This matters for Carmen Montoya specifically because chiroso's darjeeling and orange aromatics occupy a narrow extraction window — the immersion phase eliminates the slurry temperature swings that pour-over introduces with each pulse pour, keeping the anaerobic fermentation compounds extracting at a steady rate. The 89°C temperature and 525μm grind reflect the same principles as the Kalita: protect chiroso's aromatics with lower temperature, let the paper filter strip the anaerobic processing oils. The enclosed chamber also reduces evaporative loss of the volatile darjeeling-character esters during the steep, which is a specific advantage for this fragile aromatic profile.

The 74/100 match score is honest: anaerobic washed Colombian espresso is a workable but demanding preparation. Temperature drops to 88°C — the same processing and variety adjustments applying as on filter — and the ratio runs slightly longer (1:1.5-2.5 output) than a traditional Italian pull, giving extra extraction time to work through this medium-roast's intact structure. The chiroso variety's primary aromatic character doesn't concentrate favorably under 9-bar pressure the way a dense natural-process bean does; the darjeeling quality that makes it exceptional on a V60 becomes a delicate whisper under espresso's intensity. However, the anaerobic fermentation compounds do concentrate well under pressure — you should expect intense orange and raw sugar character if extraction lands correctly. Start with the 1:2 ratio and adjust from there.

The 65/100 match reflects the moka pot's structural limitations with this bean. Steam pressure through a metal filter at 95°C pre-boiled water temperature doesn't have the precision controls that define this coffee's ideal extraction window. The recipe uses pre-boiled water (which prevents the grounds from cooking as steam rises — Hoffmann's key moka pot instruction) and lands at a coarser 345μm than espresso, which partially protects the chiroso's volatiles by reducing over-extraction risk. But the metal filter passes all the oils from the anaerobic washed process into the cup, which muddies the clean fruit clarity you're paying for. If this is your only pressure method, use medium-fine grind, remove from heat the moment you hear sputtering, and expect a concentrated, oil-forward version of the darjeeling and orange notes.

French press is the weakest match here (63/100) primarily because it's a metal-filter immersion method — and anaerobic washed processing on a delicate aromatic variety is a paper-filter combination by design. The metal mesh passes all the oils and colloidal solids into the cup, which adds body but competes directly with the clean floral and citrus character that chiroso produces. The recipe pulls temperature down to 91°C (reflecting the combined effects of processing and roast level), which is on the lower end for French press. Use Hoffmann's counterintuitive technique: steep 4 minutes then wait an additional 5-8 minutes without disturbing before serving — the grounds settle, dramatically reducing sediment-driven bitterness. The raw sugar note survives well in this format; the darjeeling quality is reduced compared to paper-filter methods.

The 61/100 match score tells you this is a compromise format for Carmen Montoya. Cold water extracts melanoidins poorly and doesn't volatilize aromatic compounds at all — the darjeeling character that defines this chiroso bean is built on aromatic esters that cold immersion simply doesn't release effectively. What cold brew does do is selectively suppress bitterness by leaving CGA hydrolysis largely incomplete in the absence of heat, and the anaerobic washed process's fruit compounds partially survive in the cup as residual sweetness. Research from Fuller and Rao (2017) shows that caffeine and chlorogenic acids reach equilibrium around 6-7 hours; the 12-18 hour steep window here mainly extends melanoidin and residual compound extraction. Flash brew — hot extraction over ice — is a significantly better fit for this bean if you want cold coffee with its actual character intact.
