Pacamara was bred in El Salvador by crossing Pacas with Maragogipe — the result is one of the most physically large coffee varieties in specialty production. At Jalapa, at 1,850 meters, those already-dense beans accumulate even more organic acids and volatile precursors during the extended cherry maturation that altitude forces.
The washed process strips away fruit mucilage through tank fermentation and washing, so everything in this cup comes directly from the bean itself — the Pacamara variety and the Jalapa terroir, not fermentation byproducts. That's the defining choice with washed processing: it lets altitude and variety speak.
The grapefruit and citrus character here maps directly to citric acid. Citric is the only organic acid in coffee that consistently exceeds its sensory detection threshold in brewed coffee, which is why it dominates the perceived brightness of clean washed lots. Light roasting preserves high chlorogenic acid levels alongside the citric, keeping the pH low and the brightness forward. Push development further and CGAs convert to quinic acid, the compound responsible for the harsh aftertaste in dark roasts and stale coffee.
The nougat note comes from Maillard reaction products — specifically the browning of amino acids during roasting — landing in the middle of the extraction curve after the acids but before the dry, astringent late-extraction compounds. Pacamara's very large bean size creates an extraction consideration: the increased seed volume means water needs to penetrate further to reach the interior solubles. Washed processing gives slightly higher extraction yields than naturals overall, and at 1,850m the soluble load is considerable.
For a [Guatemalan variety](/blog/coffee-varietal-guide), Pacamara brings a complexity that goes well beyond the typical Bourbon-Caturra baseline for the region.
The 96/100 Chemex score reflects how the thick bonded paper filter interacts with this specific bean's extraction challenge. Pacamara's exceptionally large bean size — one of the largest in specialty production — means water must penetrate deeper to reach interior solubles, and at 1,850m altitude the bean is dense with accumulated organic acids and volatile precursors. The grind comes in 70μm finer than a medium default (40μm for light roast, 30μm for altitude), landing at 480μm, to compensate for both the low solubility of light roasting and the higher soluble density that altitude builds into the seed. The clean washed processing combined with thick paper filtration delivers the terroir-specific nougat and grapefruit character at maximum clarity — no fermentation esters to compete, no oils to muddy the citrus brightness.
Troubleshooting
sour: Grind finer by ~22μm and raise temp by 1°C. Pacamara's large bean size means the interior solubles — where the nougat Maillard compounds are concentrated — require more extraction time than a smaller-bean variety. If sour, the grapefruit citric acids have been pulled but not the nougat sweetness.
thin: Add 1g dose or reduce water by 15g. The Chemex's thick paper removes oils, so strength depends entirely on dissolved solids. Pacamara at 1,850m has high soluble load — thin results usually mean the grind is too coarse for the roast level. A metal filter adds body without changing dose.
At 430μm, the grind is 70μm finer than the V60 default — a significant adjustment driven by two factors. Light roast accounts for 40μm of that, because denser, less-soluble beans need more surface area to extract properly. The remaining 30μm comes from altitude: at 1,850m in Jalapa, this Pacamara has accumulated significant solubles over a slow growing season, producing a genuinely dense bean that resists water penetration. The V60's single large drain hole and ribbed walls move water faster than a flat-bottom design, which means even grinding is critical — uneven particle sizes here will produce cups that are simultaneously sour from fast-draining zones and flat from coarse particles that under-extract. Swirl immediately after the bloom to redistribute the coarser Pacamara particles across the sloping bed.
Troubleshooting
sour: Grind finer by ~22μm and raise temp by 1°C. Pacamara's large seed volume means more of the extraction has to cover physical distance inside each particle. The V60's faster flow favors smaller beans — compensate by going finer so surface area bridges the gap before drawdown completes.
thin: Add 1g dose or reduce water by 15g. The 1:15.5 ratio at light roast is lean. Pacamara's altitude-built soluble density means under-dose is the most common thin-cup cause. Try a metal filter if the cup is clean but lacks presence — paper removes oils that add body perception.
The Kalita Wave's flat-bottom geometry provides more even water distribution than a conical dripper, which directly benefits Pacamara's large, dense beans. Uneven extraction is the primary risk with oversized variety beans like Pacamara — when water distributes unevenly across the bed, some large particles extract on the outer surface (fast, sour) while inner zones remain under-extracted, producing cups that taste simultaneously sharp and flat. The Wave's design reduces this channeling risk. At 460μm and 94°C, the combined 70μm-finer grind increases surface area to partially compensate for the physical depth water must traverse into Pacamara's large seed. The 1:16.5 ratio runs slightly more water than the V60 version, which the Wave's less-channeling geometry justifies — more water provides more extraction passes across the bed.
Troubleshooting
sour: Grind finer by ~22μm and raise temp by 1°C. The Wave is more forgiving than V60 for large-bean Pacamara, but if grapefruit dominates and nougat is absent, extraction stopped early. Push grind finer — the flat bed distributes the increased resistance evenly, which is where Pacamara benefits most.
thin: Add 1g dose or reduce water by 15g. The 1:16.5 ratio is the most water-forward in this bean's brewer set. Thin results usually mean the dose is slightly off — Pacamara from this altitude needs a full 20g to express the concentrated solubles built during slow cherry maturation.
The AeroPress recipe for this Pacamara uses the standard 85°C AeroPress temperature and 330μm grind — notably fine for a non-espresso brewer. The grind is driven 70μm below default by the combined effects of light roast density and the 1,800m altitude, resulting in a setting that maximizes surface area in a concentrated immersion. The lower temperature relative to pour-over methods gives time for the nougat Maillard compounds (which extract after the first wave of grapefruit citric acids) to catch up without the brew tipping toward bitterness from the CGA levels that remain elevated in this light roast. The 1:12.5 ratio produces a more concentrated cup than pour-overs, and the immersion method ensures the large Pacamara particles get full-contact exposure rather than a single rapid percolation pass.
Troubleshooting
sour: Grind finer by ~22μm and raise temp by 1°C. At 85°C Pacamara extracts slowly, and the large bean size extends the diffusion path to interior nougat compounds. If the cup leads strongly with grapefruit and lacks sweetness, more surface area via finer grind is the primary fix.
thin: Add 1g dose or reduce water by 15g. The 1:12.5 AeroPress ratio is already concentrated, but light-roasted Pacamara from 1,850m has high soluble density. If thin, increase dose — the lower brew temperature may be extracting slightly less total yield, and dose compensates directly.
The Clever Dripper's immersion-then-drain mechanism provides a useful middle ground for this challenging bean: the 3-4 minute full-immersion steep at 94°C gives Pacamara's large beans extended contact time that a flow-through pour-over's brief water passage can't match, and then the paper filter drains clean cup without sediment or oils. At 460μm grind (70μm finer than default) and 94°C, the steep temperature is high enough to drive extraction through the light-roast density and the altitude-built soluble concentration. The key advantage over the V60 here is that the immersion removes channeling risk — all grounds steep in the same water simultaneously rather than relying on even water distribution from a gooseneck kettle. Stir the slurry after adding water to break the crust and ensure the coarser outer Pacamara surfaces don't block interior extraction.
Troubleshooting
sour: Grind finer by ~22μm and raise temp by 1°C. Clever Dripper immersion is forgiving, but Pacamara's large seed requires more time for solubles to diffuse out. If the nougat sweetness is absent and grapefruit dominates, extend steep by 30 seconds alongside the grind adjustment.
thin: Add 1g dose or reduce water by 15g. The Clever's paper filter removes oils that contribute to body perception, so all strength comes from dissolved solids. Pacamara from 1,850m has high TDS potential — thin cups indicate insufficient dose, not a brewing technique issue.
Light roast espresso demands a longer yield ratio (1:1.9-2.9) and preinfusion to distribute water evenly through the dense puck before full pressure applies — this bean's low solubility at light roast makes both adjustments essential. The grind drops 70μm finer than default — 30μm for the high altitude beyond the 40μm light roast adjustment — landing at 180μm. This very fine setting creates the hydraulic resistance needed to maintain even pressure distribution across Pacamara's large, dense grinds. At 9 bar the grapefruit citrus and nougat compounds extract together at high concentration; the longer ratio bleeds excess intensity while preserving the brightness. Start with a 6-8 second preinfusion at reduced pressure before ramping to full, which helps overcome the extraction resistance gap between Pacamara's large surface particles and its dense interior.
Troubleshooting
sour: Grind finer by ~10μm and raise temp by 1°C. At 180μm base, 10μm is a significant resistance change. Light Guatemalan Pacamara pulls bright naturally; if the shot runs under 28 seconds and tastes sharp, puck resistance is too low for the nougat sweetness to extract.
thin: Add 1g dose or reduce yield by 5g. Pacamara at 1,850m has enormous soluble density — if the shot pulls correctly by time but tastes thin, you're pulling too long a yield. Drop the output weight by 5g and reassess the balance of grapefruit and nougat.
The moka pot fires a temperature ceiling rule at 94°C (versus the 100°C this brewer would otherwise use), which is unusual — this is because Pacamara at 1,850m altitude has the altitude ceiling applied, capping the base water temp to prevent over-extraction of the light roast's still-elevated chlorogenic acid levels under pressure. The grind at 280μm is 70μm finer than a medium moka default, the largest light+altitude combined adjustment in the set. At 1.5 bar, the moka pot concentrates the grapefruit and nougat character into a dense 1:9.5 ratio cup. Pre-boiling the base water before filling is critical here — starting with cold water causes the chamber to heat the grounds with steam before extraction pressure builds, which over-extracts the outer surface of Pacamara's large beans before the basket water even reaches temperature.
Troubleshooting
sour: Grind finer by ~22μm and raise temp by 1°C. The moka pot's 94°C ceiling for this Pacamara is already conservative. If sour, the primary fix is grind — finer particles create more surface area for the limited pressure to work with, extracting nougat sweetness before the brew sputters.
thin: Add 1g dose or reduce water by 15g. Fill the filter basket fully without tamping. Light-roasted Pacamara from 1,850m is dense and high in solubles, but the moka pot needs a full basket to build sufficient extraction pressure — underfilling degrades both yield and pressure consistency.
strong: Reduce dose by 1g or add 15g water to the base. Pacamara's concentrated altitude solubles can push moka extraction over-strong. Don't coarsen the grind — that risks channeling under the modest 1.5 bar. Dilution or lighter dose preserves extraction balance.
French press scores 76/100 for this Pacamara — below the pour-overs but usable — because the metal mesh filter passes both insoluble oils and the fine sediment that naturally results from grinding large Pacamara beans. Large-bean varieties produce more surface area per particle than smaller beans at the same grind setting, which means the coarse 930μm French press grind generates proportionally more surface area than it would for a Caturra or Bourbon bean. The result can tend toward over-extraction in a long steep without careful attention. At 94°C (temperature ceiling applies from altitude) and 1:14.5, use Hoffmann's extended method: steep 4 minutes, then wait 5-8 additional minutes with the plunger lightly set but not pressed fully — this settles fines from the large Pacamara grinds before pouring.
Troubleshooting
sour: Grind finer by ~22μm and raise temp by 1°C. Light-roasted Pacamara at French press coarseness has significant extraction resistance. If the 8-minute steep still produces sour grapefruit without nougat sweetness, the grind surface area is too low — go finer rather than extending steep time.
thin: Add 1g dose or reduce water by 15g. Pacamara's large beans extract more slowly in immersion than smaller varieties at the same setting. If the cup lacks body after the full steep, increase dose. Metal mesh French press retains oils — thin results indicate insufficient coffee mass, not filter loss.
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.
