Washed processing removes the fruit before fermentation can imprint its character onto the bean. The result is that what's in the cup comes almost entirely from the seed itself — the terroir, the variety, and the roast — rather than from what happened to the cherry on the outside. For Pacamara at 1,730m, that means the variety's inherent acid complexity gets the spotlight. Apricot and plum map to malic acid, which is crisp and stone-fruit in character. Malic acid stays relatively stable through light roasting because development time is short and the acid degrades most rapidly at higher roast temperatures. Orange comes from citric acid — the only organic acid that consistently exceeds its sensory detection threshold in brewed coffee, responsible for the bright, recognizable citrus lift. Cinnamon is a spice note produced by phenylpropanoid compounds that form during Maillard development; these appear more prominently in washed coffees because the fermentation esters that dominate in naturals aren't competing for attention. Cider pulls the acidity and sweetness together — a combined effect of malic and citric acids with aroma-mediated sweetness from caramelization products. At 1,730m, Las Brumas is significantly above typical El Salvador growing altitude. Altitude explains roughly 25% of extraction yield variation, and the slower cherry maturation at higher elevation concentrates solubles in the seed. [Washed processing yields slightly higher extraction than naturals](/blog/coffee-processing-methods-explained), so this bean combines both factors that push yield upward: high altitude and clean processing. Pacamara's very large bean size means grinding behavior differs from standard Bourbon or Caturra. The large seeds produce wider particle distribution when ground, which means some portions of the bed extract faster than others. The washed processing — which produces more uniform cell structure than natural or anaerobic lots — partially compensates, but grind consistency remains the key variable for bringing apricot and cider character into balance.
Chemex 6-Cup 96/100
Grind: 510μm Temp: 94°C Ratio: 1:15.0-1:16.0 Time: 3:30-4:30

The Chemex scores 96/100 for this Las Brumas washed Pacamara precisely because its thick bonded paper does what no other filter does: it strips nearly all oils and insoluble solids, producing a cup so transparent it acts like a magnifying glass for the bean's washed character. For a washed-process coffee, that transparency is the point — the whole rationale for washing is to expose terroir and varietal character rather than fermentation-derived fruit. The 40μm grind reduction (510μm) increases surface area to compensate for light roast's lower solubility, and the slightly leaner 1:15.5 ratio ensures TDS stays in range despite that clarity. At 1,730m, the bean is soluble-dense from altitude; the Chemex's longer drawdown time relative to V60 gives those solubles time to fully dissolve, bringing out the cinnamon and cider complexity that shorter contact time leaves behind.

Troubleshooting
sour: Grind finer by ~22μm and increase temp by 1°C. The Chemex's thick paper naturally slows flow, but if still sour, Pacamara's large-particle distribution is delivering boulders that extended contact time alone can't fully extract. Finer grind reduces those coarse outliers and closes the extraction gap.
thin: Increase dose by 1g or decrease water by 15g; or try a metal filter for body. Chemex paper aggressively strips oils — with a light washed Pacamara that's already low-solubility, thin body is common. More coffee is the cleaner fix than extending brew time.
Hario V60-02 88/100
Grind: 460μm Temp: 94°C Ratio: 1:15.0-1:16.0 Time: 2:30-3:30

The V60's open cone and fast flow rate create a demanding environment for a light washed Pacamara — and the recipe responds by stepping down 40μm from default grind. That finer setting (460μm) compensates for two challenges specific to this bean: Pacamara's very large bean size produces a wider particle size distribution when ground, meaning coarser settings risk underextraction in the boulders; and light roasting means reduced solubility relative to a medium. At 94°C, you're hitting the upper-ideal range to drive more diffusion through those dense, high-altitude seeds. The result is that the V60 pulls out apricot and cider without needing the thick filter of a Chemex — you'll get slightly more mouthfeel from oils passing through the thinner paper, which rounds out the Pacamara's naturally assertive acidity into something closer to stone-fruit balance.

Troubleshooting
sour: Grind finer by ~22μm and increase temp by 1°C. Pacamara's large bean size means boulders in the bed extract last — sourness signals those boulders are underextracted, pulling only the fast-dissolving fruity acids while the balancing sweetness compounds remain locked in the coarse particles.
thin: Increase dose by 1g or decrease water by 15g; alternatively try a metal filter. Light washed Pacamara has naturally lower solubility than a medium or dark lot — increasing coffee concentration or switching to metal unlocks oils that the thin V60 paper traps.
Kalita Wave 185 88/100
Grind: 490μm Temp: 94°C Ratio: 1:16.0-1:17.0 Time: 3:00-4:00

The Kalita Wave's flat bed and three-hole drain distribute extraction evenly across the puck — a meaningful advantage with Pacamara, whose oversized beans produce particle distributions that tend toward bimodal peaks when ground. Even with a consistent burr grinder, Pacamara throws more coarse outliers than smaller-bean varieties like Caturra; the flat bed means every part of the coffee bed sees similar flow, reducing the channeling risk those outliers create. The recipe sits at 490μm (40μm below default), balanced against a 1:16.5 ratio — slightly leaner than V60 to match the Wave's typically slower draw-down. At 94°C, this hits the middle of the ideal extraction window for a dense, high-altitude washed bean. The Wave won't showcase apricot and cider with the same clarity as the Chemex, but it delivers them with better body and balance.

Troubleshooting
sour: Grind finer by ~22μm and increase temp by 1°C. The Wave's flat bed is forgiving, but Pacamara's large beans still produce coarse outliers in any grind distribution. Finer grind closes the extraction gap between the fastest-dissolving fines and the slow-dissolving boulder fraction.
thin: Increase dose by 1g or decrease water by 15g; or try a metal filter. Light washed Pacamara at the 1:16.5 ratio leans toward clarity over body — tightening the ratio to 1:15.5 is the most direct fix before adding dose, without altering extraction character.
AeroPress 82/100
Grind: 360μm Temp: 85°C Ratio: 1:12.0-1:13.0 Time: 1:00-2:00

The AeroPress at 85°C produces a denser, more balanced expression of this Pacamara. The concentrated format (1:12.5 ratio) and short steep time naturally compress the bright acidity that Pacamara carries from its high-altitude origin, letting the roast-developed sweetness — the almond and cider range — come through with more presence. The 360μm grind (40μm finer than default, adjusted for light roast density) ensures adequate surface area for extraction in the 1-2 minute brew window. The pressure plunge drives the final extraction through the fine grind efficiently, capturing sweetness compounds that need mechanical assistance to fully extract from this dense bean in such a short time. The result is a concentrated cup where apricot and cider character read with more body and sweetness than a pour-over achieves — a different expression rather than a lesser one.

Troubleshooting
sour: Grind finer by ~22μm and increase temp by 1°C. At 85°C the AeroPress already runs cool — sourness means extraction fell short before enough sweetness compounds dissolved. Finer grind is the more effective lever than increasing temp, which risks bitterness.
thin: Increase dose by 1g or decrease water by 15g; or try a metal filter. The AeroPress at 1:12 should produce a concentrated brew — if thin, dose is the issue. Metal filter passes Pacamara's oils, adding body to a naturally clean washed profile.
Clever Dripper 82/100
Grind: 490μm Temp: 94°C Ratio: 1:15.0-1:16.0 Time: 3:00-4:00

The Clever Dripper combines immersion steeping with a paper filter drain — it shares French press's contact-time advantage and Chemex's oil-stripping clarity, landing somewhere between them. For a washed Pacamara, that hybrid character is more useful than it might sound: the immersion phase gives the large Pacamara beans extended contact time to fully dissolve their solubles, while the paper filter drain clears the oils that would muddy the washed character. The recipe at 490μm and 94°C is identical to the Kalita Wave in grind and temperature, reflecting that both brewers handle similar dose sizes with comparable extraction mechanics. The key difference is the 3-4 minute immersion before drain — this extra contact time slightly increases the risk of over-extraction in fines, but Pacamara's coarser particle outliers benefit from that extended window.

Troubleshooting
sour: Grind finer by ~22μm and increase temp by 1°C. The Clever's immersion phase helps Pacamara's large beans hydrate, but if steep time is at the short end of the window (3 minutes), the boulders may still be underextracted. Extend steep first, then adjust grind.
thin: Increase dose by 1g or decrease water by 15g; or try a metal filter for more body. Paper drain on the Clever strips oils like any pour-over — with light washed Pacamara's inherently lower solubility, thin body is the expected failure mode.
Espresso 81/100
Grind: 210μm Temp: 93°C Ratio: 1:1.9-1:2.9 Time: 0:28-0:35

Light-roast espresso demands attention here for a specific reason: washed Pacamara at 1,730m is among the most difficult light-roast espresso assignments a grinder can face. High altitude means high density; washed processing means dense structure that resists water penetration; light roast means limited degassing and minimum solubility reduction from caramelization. The recipe responds with a 1:2.4 ratio (longer than a typical 1:2 ristretto), which gives more water contact time to extract through that resistance. At 210μm grind (40μm below default for light roast), the puck resistance is high enough to slow the shot appropriately. Expect the bright acidity — orange and cider from the flavor profile — to dominate in the finish; the shot will be bright and fruit-forward rather than the caramel-heavy espresso character you'd get from a darker roast.

Troubleshooting
sour: Grind finer by ~10μm and increase temp by 1°C. Light washed Pacamara is particularly prone to sour espresso — the dense bean resists extraction at coarser settings. The 1:2.4 ratio already accounts for this; grind is the precision lever here.
thin: Increase dose by 1g or decrease yield by 15g (shorter ratio). Thin espresso with this bean means insufficient TDS — either dose more coffee into the basket or pull a shorter, more concentrated shot. The light roast limits how far you can push extraction yield.
Moka Pot 79/100
Grind: 310μm Temp: 100°C Ratio: 1:9.0-1:10.0 Time: 4:00-5:00

Moka pot runs at ~1.5 bar — far below espresso's 9 bar — but enough pressure to extract more efficiently than immersion or pour-over. The 310μm grind (40μm below default, reflecting the light roast's lower solubility) is medium-fine rather than espresso-fine; tamping is never appropriate for moka, which would create channeling under the lower pressure. Using pre-boiled water in the base is especially important with this washed Pacamara: starting with cold water means the grounds sit in the rising steam before extraction begins, which cooks the coffee and amplifies the astringent bitter compounds that are already elevated in light roast washed beans from their higher acidity. The 1:9.5 ratio concentrates the brew, which is appropriate — moka's efficiency means you get more soluble extraction per gram, so dilution is part of the drinking experience.

Troubleshooting
sour: Grind finer by ~22μm and increase temp by 1°C. Light roast Pacamara needs maximum extraction efficiency in the moka pot's short brew window — the 1,730m altitude density resists even the medium-fine 310μm setting. Sourness means the grind is still too coarse for this bean.
thin: Increase dose by 1g or decrease water by 15g. Moka's concentrated ratio should yield a dense brew — thin output means under-dosing or too much water relative to coffee. This bean's light roast limits available solubles, so dose adjustments work faster than grind changes.
strong: Decrease dose by 1g or increase water by 15g. If the concentrated moka extraction of this washed Pacamara is overwhelming, diluting the ratio is the correct fix — the assertive citric and malic acids that define this bean's character can become harsh at excessive TDS.
French Press 76/100
Grind: 960μm Temp: 96°C Ratio: 1:14.0-1:15.0 Time: 4:00-8:00

French press scores 76/100 for Las Brumas washed Pacamara, and the mismatch is mechanical: metal mesh filtration passes oils and fines that paper would catch, adding body and texture to a coffee whose washed-process character is specifically built for clarity. That said, the recipe accounts for this — 960μm grind (40μm below the already-coarse French press baseline) reduces the fine particles that cause bitter, gritty extraction in immersion. At 96°C (2°C above pour-over temps), the press compensates for light roast's reduced solubility with additional thermal energy. The extended steep window (4-8 minutes) lets Pacamara's dense high-altitude seeds fully hydrate at coarse grind. You'll lose the bright cider clarity, gaining a heavier, slightly fuller expression of the stone-fruit notes — plum reads more clearly here than it does through paper.

Troubleshooting
sour: Grind finer by ~22μm and increase temp by 1°C, or extend steep toward the 8-minute end. Light washed Pacamara needs more contact time than typical beans at coarse press grind — acidity signals the dense seeds haven't fully hydrated yet.
thin: Increase dose by 1g or decrease water by 15g. French press metal mesh already contributes body via oils and fines. If still thin, the issue is concentration — this bean's light roast and washed processing give it lower available solubles than a darker or natural lot.
Cold Brew Flash 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.
