A blend from 400 smallholder members of a single cooperative means this lot is built from averaging — dozens of different farm elevations, microclimates, and harvest windows pooled into one consistent profile. What COOCAFISA in Caicedo gives you is the aggregate expression of Antioquia's growing conditions at 1,675 meters, which sits at the lower edge of Colombia's specialty altitude band.
The variety mix is worth paying attention to. Caturra brings bright citric acidity — it's a Bourbon mutation that produces dwarf plants suited to higher-density planting, with a characteristic brightness. Bourbon itself adds sweetness and complexity from its distinct flavor lineage. Chiroso is an Antioquia regional landrace with some genetic distance from the Bourbon-Typica mainstream, contributing the floral dimension that makes this origin interesting.
Light roasting preserves the organic acids that cooler growing temperatures at this altitude helped accumulate. Chlorogenic acids remain high at light roast — they're the primary source of perceived brightness, and they degrade rapidly as roast level increases. The peach and fresh cream notes connect to separate mechanisms: peach character traces to volatile esters and malic acid in the stone fruit range; cream is a mouthfeel quality influenced by melanoidins from early Maillard development, which begin forming even at light roast temperatures.
Washed processing strips the fruit layer away, leaving behind a clean cup that lets the variety blend and terroir speak without fermentation-derived esters competing. At 1,675 meters, this is slightly less soluble-dense than Colombian lots grown at 1,850 or 2,000 meters — altitude explains roughly 25% of extraction yield variation — which means the extraction window is a touch more forgiving, but also means pushing it too hard will show thinness faster than higher-grown lots would.
Chemex scores 96/100 for this bean — tied for the highest rating — because the combination of thick filtration and washed processing creates the ideal environment for Chiroso's floral dimension. The Chemex filter removes not just oils and fines, but the micro-particulates that can create a background muddiness at these finer light-roast grind sizes. Chiroso's floral compounds are delicate and easily masked; stripping competing elements with heavy filtration is exactly right. The 500μm grind at 93°C through a slow-flowing Chemex filter creates extended contact time that compensates for the -50μm light-roast-plus-variety grind adjustment. The peach volatile esters and fresh cream melanoidin mouthfeel both land in the cup's middle phase — the Chemex's longer brew time increases the probability of reaching that phase cleanly.
Troubleshooting
sour: Grind 22μm finer and raise temp 1°C to 94°C. The thick Chemex filter and already-fine 500μm grind mean flow is controlled — sourness here usually means insufficient temperature rather than poor grind size. The Chiroso variety adjustment ran temp down to 93°C; pushing to 94°C is safe if brightness dominates unpleasantly.
thin: Add 1g coffee or cut 15g water, or try a metal filter. El Ramo's 400-farm cooperative blend means average solubility at 1,675m — below Colombia's highest-altitude lots. A metal filter passes oils that the Chemex strips, adding perceived body without changing ratio. If you want maximum Chiroso floral clarity, increase dose instead.
At 450μm — 50μm finer than default — this recipe pushes extraction harder than a standard medium-roast Colombian. The light roast accounts for 40μm of that finer grind, and the remaining 10μm reflects the multi-variety blend's aromatic complexity. Temperature drops to 93°C, protecting the delicate aromatic character of Chiroso: this Antioquia regional landrace carries floral compounds that are volatile and extract quickly at higher temperatures, so dialing back 1°C preserves them. The V60's conical geometry and thin paper filter will pass the Bourbon and Caturra body into the cup while maintaining the clarity that lets Chiroso's distinctive florals appear. At 1:15.5, you're on the richer side for pour-over, compensating for this 1,675m Antioquia lot's slightly lower solubility than higher-altitude Colombian coffees.
Troubleshooting
sour: Grind 22μm finer and raise temp 1°C to 94°C. At 1,675m, El Ramo is extractable but not as soluble-dense as farms at 1,850-2,000m. Sourness means extraction stalled in the acid phase — the peach and cream haven't come through yet. The variety(-1) temp modifier is conservative; 1°C up is safe.
thin: Add 1g coffee or remove 15g water. The cooperative's pool of 400 smallholders means lot-to-lot density variation is higher than single-farm Colombian lots — some bags will extract leaner. Increasing dose is more consistent than adjusting technique when thinness appears.
The Kalita Wave's even flat-bottom extraction is well-suited to a cooperative blend like El Ramo: the flat bed minimizes the channeling risk that would disproportionately extract from one zone of a heterogeneous grind bed. With 400 farms averaging into one lot, individual cherry maturity variation is higher than a single-farm lot — some beans may extract slightly faster, others slower. The flat-bottom geometry's uniform water-to-grounds contact averages this out better than the V60's cone, which concentrates flow toward the center. The 480μm grind at 93°C is the finest and coolest of the three pour-over methods, with the finer setting protecting Chiroso florals across all brewing contexts. The 3-4 minute target time sits comfortably within the extraction window that gets peach and cream through the filter without hitting the bitter compounds bitter phase.
Troubleshooting
sour: Grind 22μm finer and raise temp 1°C. The Kalita's even extraction means sourness is rarely about channeling — it's about under-extraction across the board. This cooperative Caturra-Bourbon-Chiroso blend at 1,675m needs the finer grind and 94°C to push through the acid-dominant early phase into peach and cream territory.
thin: Add 1g coffee or cut 15g water. The Kalita Wave's consistent extraction is a strength for this cooperative blend, but consistency works both ways — if dose is low, it extracts evenly but weakly. At 1:16.5, you're already on the lean side; pulling to 1:15 via dose increase is the first fix.
At 84°C — the lowest temperature recipe for this bean — AeroPress is protecting Chiroso's volatile aromatic compounds through cool-temperature selective extraction. Slurry temperatures run 5-15°C lower than kettle temperature even in open drippers; in AeroPress's enclosed chamber, heat retention is better, so 84°C kettle yields a slurry closer to 80-82°C. That range selectively mobilizes peach esters and vanilla-adjacent melanoidins without aggressively extracting the chlorogenic acids that would overpower the delicate Chiroso florals. The 350μm fine grind compensates for the cool temperature — finer particle size provides more surface area to maintain extraction rate despite reduced thermal energy. This is the method where vanilla and peach will be most prominent relative to acidity.
Troubleshooting
sour: Grind 22μm finer and raise temp 1°C to 85°C. The 84°C starting point is conservative specifically for Chiroso's aromatic protection — but if the coffee is tasting sour rather than bright, extraction is insufficient. Raise temp before lengthening steep time; temperature uniformly increases the diffusion coefficient.
thin: Add 1g coffee or cut 15g water. The AeroPress at 1:12.5 with fine grind is already in concentrated territory for this light-roast Colombian. If the cup reads thin, dose is likely the issue — the cooperative blend's variable density means some bags need the extra gram to hit target strength.
The Clever Dripper's immersion-plus-filtration approach is a good middle ground for this four-variety blend: the 3-4 minute steep allows more uniform extraction across the different variety characteristics (Caturra's brightness, Bourbon's sweetness, Chiroso's florals, Variedad Colombia's body contribution) than a single-pass pour-over, and the paper filter then strips the sediment that would muddy Chiroso's aromatic expression. At 480μm and 93°C, the recipe mirrors the Kalita parameters closely, which makes sense — both methods aim for balanced extraction at moderate contact time. The Clever's closed chamber during steeping maintains temperature better than the open Kalita, which is a slight advantage for this cool-temperature recipe.
Troubleshooting
sour: Grind 22μm finer and raise temp 1°C. The Clever's immersion phase gives this cooperative blend's heterogeneous variety mix time to even out — but if still sour, grind adjustment before time adjustment is correct. The peach volatile esters and cream melanoidins need adequate contact surface to dissolve within the 3-4 minute window.
thin: Add 1g coffee or cut 15g water. The Clever's paper filtration removes body-building oils, making it slightly thinner than French Press by design. For this 1,675m Colombian, dose adjustments matter more than technique changes — the filtration effect is fixed. If consistently thin, try a slightly shorter release time to keep brew warmer.
The light-roast espresso parameters bring this bean to 92°C — even lower than the already-moderated pour-over temperature of 93°C — and extend the output ratio up to 1:3.4. At 200μm grind and 9 bar pressure, the Chiroso floral compounds will express as perfumed sweetness rather than identifiable florals at espresso concentration; they compress into the cup's aromatic background. The peach character survives concentration pressure better — stone fruit esters are relatively robust at espresso temperatures compared to jasmine-type volatiles. Expect the shot to read sweet, peach-forward, with cream sweetness in the finish and Bourbon's body providing the frame. Preinfusion is non-negotiable here: this light-roast washed bean at 200μm needs even puck saturation before full pressure to prevent channeling that would create an undrinkable simultaneously sour-bitter shot.
Troubleshooting
sour: Grind 10μm finer and raise temp 1°C to 93°C. Light-roast washed Colombian espresso at this variety blend's density requires precise grind adjustment — 10μm at espresso fineness is meaningful. Evaluate one click at a time. If using a low-volume portafilter basket, consider WDT distribution to prevent channeling that mimics sourness.
thin: Add 1g to dose or reduce output ratio. This bean's wide output ratio window (1:1.9-3.4) is intentional for light-roast adaptability — thin shots mean you've extended ratio too far or dose is too low. Increase dose by 1g first before compressing the ratio, since a short, thin shot suggests underdose.
At 99°C with a 300μm grind, Moka Pot will compress this four-variety blend into its most intense, roasted-character expression. The Chiroso florals will largely volatilize at this temperature before they reach the cup — what remains is the Caturra and Bourbon character: the citric-bright acidity compressed into a sharper edge, the cream mouthfeel as a rich thickness, and the peach character shifting toward stone-fruit jam at higher concentration. The recipe's dose at 18g is consistent with the other methods despite the intensity, which produces a 1:9.5 concentrate. Using pre-boiled water is more critical here than for single-variety beans: the heat ramp through cold water would spend extra time in the 70-85°C range where CGA degradation accelerates, adding bitterness before the proper brew temperature is reached.
Troubleshooting
sour: Grind 22μm finer to 278μm. The Moka Pot can't easily vary temperature — pre-boiled water and low-medium heat are fixed. Grind finer to increase surface area and compensate for any under-extraction of this light washed Caturra-Bourbon. The Chiroso variety modifier already set temp expectations low; grind is your primary adjustment.
thin: Add 1g coffee or reduce water by 15g. The Moka Pot's fixed chamber volume limits options, but small dose increases within the basket are effective. At 1:9.5, you're in concentrate territory — if thin, the most likely cause is insufficient dose rather than under-extraction, since 99°C provides adequate thermal energy.
strong: Reduce dose by 1g or add 15g water. The Moka Pot's high temperature and moderate pressure can over-concentrate when dose is generous. If the cup tastes harsh-strong rather than bright-intense, back off dose by 1g — the four-variety blend extracts slightly more readily than single-variety beans due to processing variation.
French Press at 95°C with 950μm grind is the least favorable presentation for this bean's distinctive attributes. Chiroso's floral character — the compound that separates El Ramo from generic washed Colombians at this altitude — is delicate and easily masked by the oils and fines that French press passes into the cup. The coffee oils carry cafestol and kahweol (unfiltered method), adding body but muddying the fresh cream and peach clarity. The narrow 0.5°C temperature reduction to 95°C (rather than the standard 96°C) provides consistent protection of aromatic compounds, the same approach applied across all methods for this bean.
Troubleshooting
sour: Grind 22μm finer and raise temp 1°C to 96°C. French Press's coarse 950μm grind relies on extended immersion to extract from low-solubility light-roast cells, but sourness means even the steep isn't completing the extraction. Finer grind accelerates this without requiring longer time that would develop unwanted bitterness.
thin: Add 1g coffee or cut 15g water. The French Press passes oils that add body, but the cooperative blend's moderate 1,675m density means extraction yield is capped. Increasing dose is the most direct path to higher TDS — this bean won't extract more aggressively from longer steeping beyond 8 minutes.
Cold BrewFlash Brew Recommended
Cold brew is not recommended for this bean. At near-freezing temperatures, cold water cannot extract the complex acids, delicate aromatics, and bright fruit compounds that define a light-roasted coffee — they remain locked in the cell matrix. For a cold version of this coffee, use flash brew: brew a concentrated pour-over (V60 or Chemex at 60% of the normal water volume) directly over ice in the server. The hot water extracts the full flavor spectrum, and the rapid ice cooling locks in volatiles that would otherwise evaporate during a slow cool-down.
