Washed processing at 1,700 meters in Caranavi, medium-dark roasted — this is the Bolivian category norm. No unusual fermentation, no deviation in roast level. What that means is the narrative here lives entirely in the chemistry of what these specific conditions produce, and why medium-dark development works with them rather than against them.
The washed process strips mucilage through fermentation and washing before drying, which produces clean, bright cups with higher extraction yields than naturals. What reaches the grinder is a direct expression of what the terroir and varieties embedded in the bean. At 1,700 meters, cherry maturation slows to nine months or longer — the diurnal temperature differential preserves photosynthesized sugars overnight rather than burning them through respiration, and organic acid and volatile precursor concentration builds over that extended development cycle.
The orange, peach, and pineapple notes are the visible output of that acid chemistry. Citric acid drives the orange and bright citrus character — it's the only organic acid in coffee that consistently exceeds its sensory detection threshold. Malic acid contributes the crisp, stone-fruit quality behind the peach. The pineapple note leans phosphoric: phosphoric acid tastes sweeter and mellows citrus to tropical fruit character. Unlike citric and malic, phosphoric acid isn't degraded by roasting — it's a terroir constant controlled by the soil and variety, not the roaster.
Medium-dark development degrades chlorogenic acids into quinic acid, which shifts the acidity from the bright, citrus-forward range into something more muted and round. The Maillard reaction at this development level builds melanoidin content — 10-18% of roasted coffee dry weight — contributing to the heavier body and chocolate undertones that make this profile comfortable and approachable rather than demanding.
Cold Brew scores 87/100 for the Gutierrez Family — the top-ranked brewer for this bean. At 1°C and a tight 1:6.8-1:7.8 ratio, the recipe is optimized for a medium-dark washed Bolivian. Cold water extracts fewer bitter compounds because the harsh roast-derived bitterness that builds during medium-dark development is less soluble at low temperatures. What comes through instead is the smooth body from roast development and the bright fruit character — the orange and pineapple notes in the profile emerge more cleanly because the harsh bitter background stays suppressed. The grind at 920μm (slightly coarser than default) is standard coarse cold brew territory for a 12-18 hour steep.
Troubleshooting
bitter: Grind coarser by ~22μm and lower temperature by 1°C. While cold water extracts bitter compounds slowly, this medium-dark washed Bolivian has already elevated its quinic acid content through roasting. If steep runs long or grind is fine, bitter compounds accumulate. Research shows sensory peak at 14 hours — don't extend past 18.
strong: Decrease dose by 1g or increase water by 15g. Cold brew concentrate at 1:6.8-1:7.8 is designed for dilution — straight consumption will always read as heavy. If the concentrate itself is too dense, widen the ratio in 10g water increments rather than shortening steep time, which would reduce extraction uniformity.
flat: Grind finer by ~22μm and increase temperature by 2°C; check bean freshness and water mineral content. This washed Bolivian medium-dark should extract smoothly in cold brew — if it tastes flat, beans are likely stale or water mineral content is insufficient. Cold extraction requires reasonable mineral hardness to dissolve compounds effectively.
Espresso scores 85/100 for the Gutierrez Family. The recipe runs at 90°C (3°C below default), reflecting medium-dark development where this Bolivian still has some of its bright acid character intact. The orange and peach notes from this Caranavi lot contribute a pleasant brightness to the espresso's front end before the deeper roast-developed sweetness takes over on the finish — the lower temperature helps those fruit notes express cleanly without over-extracting the bitter compounds that medium-dark roasting creates. Grind at 270μm (slightly coarser than default) runs coarser than typical for medium-dark espresso, but this high-altitude Bolivian's elevated solubility makes it extract efficiently at coarser settings, reducing channeling risk without sacrificing yield.
Troubleshooting
bitter: Grind coarser by ~10μm and drop temperature by 1°C. Under 9-bar pressure, quinic acid and phenylindanes from this medium-dark washed Bolivian extract quickly. Smaller grind increments matter more in espresso; 10μm is sufficient to shift extraction meaningfully. Temperature adjustment compounds the effect.
strong: Decrease dose by 1g or increase water by 15g. The 1:1.3-1:2.3 ratio already constrains output — for this high-altitude Bolivian's elevated solubility, pull toward the 1:2.3 end of the range before reducing dose or touching the grinder when the shot is on-time but too intense.
AeroPress scores 84/100 for the Gutierrez Family — the same as for Espresso and Clever Dripper, making it a top-tier choice. At 82°C (-3°C), the temperature is low for AeroPress standards but appropriate for medium-dark washed Bolivian: the orange, peach, and pineapple notes — the bright acidity this bean carries — are still partially present at medium-dark roast, and lower temperatures preserve them by slowing the extraction of bitter compounds that medium-dark development produces. The 420μm grind (+20μm) keeps flow resistance manageable while ensuring the 1-2 minute contact time fully dissolves the caramelization products and melanoidins that make this lot's body work. AeroPress's optional paper filter keeps the cup clean; metal filter would add oil-based body at the cost of some sediment.
Troubleshooting
bitter: Grind coarser by ~22μm and drop temperature by 1°C. AeroPress at 82°C already limits quinic acid extraction, but extending brew time past 2 minutes or using too fine a grind will pull the medium-dark Bolivian's bitter compounds into the cup. Coarser grind is the primary lever; temperature adjustment is secondary.
strong: Decrease dose by 1g or increase water by 15g. This washed Bolivian at medium-dark runs high solubility — the AeroPress's concentrated 1:12.8-1:13.8 ratio can overshoot TDS quickly. If the cup is on-time but too dense, widen the ratio in small steps before touching grind or temperature.
Clever Dripper scores 83/100 for the Gutierrez Family, close to the top tier. The immersion phase at 91°C builds up the full melanoidin-rich body from this medium-dark lot's elevated melanoidin content, while the paper filter at drawdown removes the oils that could push the cup oily or muddy. What remains is a clear expression of the Caranavi terroir: the orange and peach acid character softened and rounded by medium-dark development, supported by substantial body from the melanoidins that extended Maillard reaction builds. The 550μm grind (+20μm) and 3-4 minute immersion time allow the caramelization products from medium-dark development to fully dissolve into the slurry before drawdown. The slightly tighter ratio (1:15.8-1:16.8) compensates for medium-dark's reduced volatile brightness by keeping TDS high enough for body to register.
Troubleshooting
bitter: Grind coarser by ~22μm and drop temperature by 1°C. Clever Dripper's closed-valve immersion concentrates extraction before drawdown, and this medium-dark Bolivian's quinic acid can dominate if steep time extends or grind runs fine. Coarser grind reduces fines that extract bitter compounds disproportionately during immersion.
strong: Decrease dose by 1g or increase water by 15g. The immersion phase extracts efficiently from this high-solubility medium-dark lot, and TDS can run above the 1:15.8-1:16.8 target if dose is generous. Widen the ratio in 1g increments before adjusting grind when the cup is on-time but too concentrated.
Moka pot scores 82/100 for the Gutierrez Family. At 97°C (-3°C) pre-boiled base water, the temperature is near-boiling but that's moka pot's working range — the steam pressure that builds in the base is what drives extraction, and reducing base water temperature too much undermines pressure development. The 370μm grind (+20μm from default) compensates for the near-boiling temperature by creating sufficient flow resistance to extend extraction time through the basket, allowing the caramelization products and melanoidins from this medium-dark Bolivian lot to fully dissolve without the shot running too quickly. The slightly tighter ratio (1:9.8-1:10.8, -0.5 from default) reflects medium-dark's good but not exceptional solubility — the moka pot shouldn't run lean at this ratio. The round, stone-fruit character that washed Bolivian processing produces at medium-dark development expresses well in this concentrated, pressure-driven format.
Troubleshooting
bitter: Grind coarser by ~22μm and remove from heat immediately when sputtering begins. Near-boiling water extracts quinic acid aggressively from this medium-dark Bolivian lot. Extended heating after extraction begins concentrates bitter compounds rapidly — timing the removal is as important as grind adjustment.
strong: Decrease dose by 1g or increase water by 15g. The moka pot's near-boiling pressure extraction runs TDS high with this high-altitude Bolivian's elevated solubility. The 1:9.8-1:10.8 ratio is already concentrated — widen toward 1:11 before touching grind when the cup is on-time but too dense.
French Press scores 82/100 for the Gutierrez Family because the metal filter passes the oils and melanoidins that paper filters trap, and those compounds are exactly what a medium-dark washed Bolivian needs to carry its body. At 93°C (-3°C), the temperature is higher than AeroPress because the extended steep time at coarser grind (1020μm) creates a different extraction profile — the longer steep at a coarser grind allows time for caramelization products and melanoidins to fully dissolve while the coarser particle size limits fines that would over-extract bitter quinic acid during the 4-8 minute window. The ratio runs slightly tighter at 1:14.8-1:15.8 compared to the default, reflecting medium-dark's slightly lower extraction ceiling. The residual orange, peach, and pineapple acid character from the Caranavi terroir softens into round citrus and stone fruit against the heavy body.
Troubleshooting
bitter: Grind coarser by ~22μm and drop temperature by 1°C. French press immersion gives this medium-dark washed Bolivian extended contact time — quinic acid builds steadily. Limiting fines with a coarser grind is the most effective correction; even minor fines accumulation drives disproportionate bitter compound extraction in an immersion steep.
strong: Decrease dose by 1g or increase water by 15g. The metal filter passes oils that increase perceived TDS on top of medium-dark's already elevated melanoidin content. When the cup reads heavy but on-time, widen the ratio before touching steep time — steep time adjustment changes extraction character, not just concentration.
Kalita Wave scores 80/100 for the Gutierrez Family. The flat-bottom design and three-hole drainage produce more even extraction across the coffee bed, which matters for a blend of Caturra, Typica, and Catuai at medium-dark roast. The Kalita's even flow distribution reduces the channeling that occurs when faster-extracting particles from varied particle sizes drive extraction while others lag. At 91°C and 550μm (+20μm coarser for the medium-dark roast's increased solubility), the recipe is cautious enough with extraction that the orange and peach acid notes have space to show without the quinic acid character of the medium-dark development dominating.
Troubleshooting
bitter: Grind coarser by ~22μm and drop temperature by 1°C. Medium-dark roasting has converted much of this washed Bolivian's chlorogenic acids to quinic acid — the Wave's even extraction is protective but can't compensate for grind that's too fine. Coarser grind limits fines that accelerate bitter compound extraction.
thin: Increase dose by 1g or decrease water by 15g; try a metal filter for more body. The Kalita's paper removes oils this medium-dark washed Bolivian needs for textural balance — medium-dark development mutes the acids, so oils and melanoidins must carry the cup. Dose adjustment is faster than swapping filter materials.
The V60 scores 69/100 for the Gutierrez Family — a low match driven by a structural mismatch between the V60's design and medium-dark roast character. The V60's fast cone drainage and emphasis on clarity strip body from a medium-dark roast that derives its appeal from melanoidin-rich texture and the muted, round acid character that medium-dark development produces from this Caranavi washed lot. Temperature drops to 91°C (-3°C), limiting extraction of bitter compounds that develop during medium-dark roasting. Grind is 520μm (+20μm), running coarser than most pour-overs at this roast level because the higher solubility of medium-dark Caturra, Typica, and Catuai varieties means extraction runs fast — the coarser particle size prevents the bitter end of the curve from dominating before the orange and peach-adjacent notes emerge.
Troubleshooting
bitter: Grind coarser by ~22μm and drop temperature by 1°C. This washed Bolivian lot at medium-dark carries significant quinic acid from CGA degradation during extended development. The V60's fast flow is already protective, but fines will over-extract bitter compounds from the medium-dark Caturra and Typica particles if grind is too fine.
thin: Increase dose by 1g or decrease water by 15g; consider a metal filter for more body. The V60's paper filter removes the oils that carry perceived body, and medium-dark roast reduces brightness, leaving the cup without either side of the flavor equation. Increasing dose is the first correction before changing equipment.
Chemex scores 65/100 for the Gutierrez Family — the lowest match among all brewers for this bean. This washed Bolivian at medium-dark roast has a flavor profile that relies on the interplay between the orange and peach brightness (still partially present at medium-dark) and the round roast-developed body. Chemex's extra-thick filters strip the oils that carry body and mouthfeel, leaving the acid character — already softened by medium-dark development — to carry a cup that no longer has enough body to balance it. The result reads as thin and slightly astringent. Temperature is 91°C and grind 570μm, both pulling back on extraction to prevent over-pulling the bitter compounds that medium-dark development creates. The Clever Dripper or French Press would preserve the body that makes this lot's round character work.
Troubleshooting
thin: Increase dose by 1g or decrease water by 15g; try a metal filter for more body. Chemex's filter strips oils that this medium-dark washed Bolivian needs for textural balance. At medium-dark roast, acids are partially degraded, so the oils and melanoidins carry the cup — removing them leaves the profile flat.
bitter: Grind coarser by ~22μm and drop temperature by 1°C. Chemex's slower drawdown extends dwell time with the grounds, amplifying extraction of quinic acid that medium-dark roast development has built from CGA degradation in this Caranavi lot. Coarser grind and lower temperature reduce the extraction rate for these bitter compounds.
