el salvador light roast washed bourbon, pacas
stewed plumbrown sugarblood orange

Chalatenango sits in northern El Salvador, a department that borders Honduras at elevations that push into genuine specialty altitude. This lot blends Bourbon with Pacas — a naturally occurring Bourbon mutation first identified in El Salvador in 1949, named after the Pacas family on whose farm it was found. Bourbon and Pacas are closely related genetically, both in the Bourbon-Typica group, so they roast similarly and cup compatibly. Bourbon brings its characteristic sweetness and delicate complexity; Pacas, a dwarf mutation, brings similar flavor chemistry in a more compact, higher-yielding plant. Stewed plum character at light roast comes from the interaction of malic acid and residual fermentation compounds from tank fermentation during washed processing. Malic acid — the crisp, stone-fruit acid — contributes at light roast levels before it degrades in development. The "stewed" quality, rather than fresh-fruit brightness, points to moderate caramelization of sugars: enough Maillard development for some complexity without pushing into the Strecker-degradation zone that produces darker, drier fruit notes. Brown sugar is aroma-mediated sweetness. Sucrose is nearly 100% consumed during roasting, but caramelization products — furanones, maltol — create olfactory signals the brain interprets as sweet. At light roast, these are in their early-stage form: simple, clean, lacking the heavier molasses quality that comes with extended caramelization. Blood orange is citric acid expressing at the sharp, tart end of its sensory range — citric is the only organic acid in coffee that consistently exceeds its sensory detection threshold, and at light roast levels, high chlorogenic acid concentrations add to the brightness. [Washed processing](/blog/coffee-processing-methods-explained) removes the fruit mucilage variables, so this acidity is purely terroir- and roast-driven: what the soil and altitude put in, and what light roasting preserved.
Chemex 6-Cup 96/100
Grind: 510μm Temp: 94°C Ratio: 1:15.0-1:16.0 Time: 3:30-4:30

Chemex earns the top score for Chelazos because the thick bonded filter pairs precisely with what washed Bourbon-Pacas delivers: clean, terroir-forward acidity. At 510μm (40μm finer than default to account for light roast density) and 94°C, the Chemex setup is designed to extract through the stewed plum and blood orange acids in the middle extraction phase rather than stalling at the harsh early-phase bitterness. The 1:15.5 ratio ensures enough dissolved solids to carry the blood orange's citric brightness — which consistently exceeds its sensory threshold in brewed coffee — without the dilution that would lose the stewed plum's more subtle malic acid character. The Chemex's 20-30% thicker filter also removes the micro-fines that would add bitterness and mask the brown sugar aroma-mediated sweetness from early-stage caramelization products.

Troubleshooting
sour: Grind finer by ~22μm and raise temp to 95°C. At light roast, blood orange brightness crosses into sharpness when chlorogenic acids dominate early extraction. Finer grind and higher temp push past the acid-dominant phase into the brown sugar Maillard window.
thin: Increase dose by 1g or reduce water by 15g. The Chemex filter removes oils; thin body here means TDS is too low, not a filter problem. A metal filter would add body but muddy the clean washed acidity that defines this bean.
Hario V60-02 88/100
Grind: 460μm Temp: 94°C Ratio: 1:15.0-1:16.0 Time: 2:30-3:30

The V60 at 460μm and 94°C extracts this Bourbon-Pacas lot in the 2:30-3:30 window that aligns with its moderate solubility. Bourbon variety at 1,500m altitude produces medium-density beans — not as dense as the highest Ethiopian altitude coffees, but denser than lower-altitude Central American lots — and the 40μm finer grind compensates for that density at light roast. The V60's conical geometry creates a gravity-fed drawdown that suits the clean washed profile here: there are no natural process fermentation compounds or honey process mucilage residuals to manage, so the V60's technique-dependent flow rate works with a consistent, predictable extraction curve. The stewed plum malic character develops through the first half of extraction; blood orange citric emerges as the brew progresses through the mid and late phases.

Troubleshooting
sour: Grind finer by ~22μm and raise temp to 95°C. Washed Bourbon-Pacas at light roast is clean but can be sharp when under-extracted. Blood orange becomes harsh rather than bright when extraction stalls early. Tighten grind before extending brew time.
thin: Increase dose by 1g or reduce water by 15g. V60 with light roast often under-extracts if drawdown is too fast — check your grind produces a 2:30-3:30 total brew time. If timing is correct, adjust ratio.
Kalita Wave 185 88/100
Grind: 490μm Temp: 94°C Ratio: 1:16.0-1:17.0 Time: 3:00-4:00

Chelazos at 490μm on the Kalita Wave benefits from the flat-bed's forgiving flow rate. Bourbon and Pacas are closely related Bourbon-group varieties with similar density and grinding characteristics — this is a more homogeneous lot than the six-variety Colombia La Colmena — so the Kalita's uniform saturation isn't correcting for variety variance but instead provides even extraction of a consistent particle distribution. At 94°C and 20g/330g (1:16.5 ratio), the setup pulls a slightly leaner cup than the Chemex, which suits the blood orange brightness: a higher water ratio lets citric's clean tartness express at the right intensity without amplifying it into sharpness. The five 50g pulse pours match standard Kalita technique and prevent over-saturation on the wave filter's edges.

Troubleshooting
sour: Grind finer by ~22μm and raise temp to 95°C. The Kalita's flat bed distributes water evenly, so sourness here is almost certainly grind-related rather than pour technique. Confirm you're not pouring on the filter walls — that causes bypass and uneven extraction.
thin: Increase dose by 1g or reduce water by 15g. The Kalita's 1:16.5 ratio is leaner than V60 by design; thin output means tightening the ratio. Don't collapse the wave filter with aggressive pours — uneven saturation reduces effective extraction.
AeroPress 82/100
Grind: 360μm Temp: 85°C Ratio: 1:12.0-1:13.0 Time: 1:00-2:00

AeroPress at 85°C and 360μm — 40μm finer than standard for the light roast — produces a concentrated, punchy cup of this El Salvadoran. The fine grind and the pressure during plunging maintain adequate extraction within the short 1-2 minute brew window, pulling the stewed plum and brown sugar compounds cleanly. The 1:12.5 ratio produces a concentrated format that works well for the blood orange's citric structure — citric acid at this concentration reads as clean tartness rather than sharpness. Bourbon and Pacas both have medium-density beans that extract predictably in the AeroPress, without the channeling behavior that denser, higher-altitude beans can produce under pressure.

Troubleshooting
sour: Grind finer by ~22μm and raise temp to 86°C. AeroPress with washed Bourbon-Pacas at light roast is sensitive to under-extraction at the lower temperature. Stir for 10 seconds before pressing to ensure even wetting of the light-roasted, higher-density bed.
thin: Increase dose by 1g or reduce water to 165g. AeroPress thin output usually means the ratio has drifted or the press was too slow. A 20-second press maintains pressure; grinding finer concentrates TDS by slowing the flow through the puck.
Clever Dripper 82/100
Grind: 490μm Temp: 94°C Ratio: 1:15.0-1:16.0 Time: 3:00-4:00

The Clever Dripper's immersion-then-filter approach works for Chelazos by extending contact time without adding mouthfeel from oils. At 490μm and 94°C with a 3:00-4:00 brew window, the immersion phase gives Bourbon and Pacas's medium-density beans adequate time to release the malic-acid stewed plum compounds, which extract more slowly than the citric blood orange acids. The paper filter then removes the suspended solids from the steep without the fines that a French Press passes. For a washed light roast where the profile is built on clean terroir and bright acid balance, the Clever's paper filter produces an outcome almost identical to the V60 but with less technique-dependency — a reliable option when you want repeatability over precision.

Troubleshooting
sour: Grind finer by ~22μm and raise temp to 95°C. The Clever's steep time should carry extraction past the acid-dominant phase, but light roast density can resist diffusion even in full immersion. Ensure the lid is on during steep to maintain temperature throughout.
thin: Increase dose by 1g or reduce water by 15g. The Clever's paper filter removes oils that add body; if the ratio is right, body comes from dissolved solids, not lipids. Don't switch to metal filter — clean acidity is this bean's defining character.
Espresso 81/100
Grind: 210μm Temp: 93°C Ratio: 1:1.9-1:2.9 Time: 0:28-0:35

This Bourbon-Pacas washed light scores 81/100 for espresso — higher than the Colombia La Colmena — partly because the two-variety blend produces a more uniform puck than a six-variety lot. Bourbon and Pacas grind similarly, creating consistent hydraulic resistance across the portafilter bed. Light-roast espresso calls for 93°C with a 1:2.4 ratio (19g/45g): the longer ratio than a traditional 1:2 espresso compensates for the light roast's lower solubles concentration. Blood orange at espresso concentration registers as a vivid citric tartness in the front of the shot; stewed plum and brown sugar carry through the mid and tail. Expect a bright, acidic shot — preinfusion at low pressure before full pump engagement prevents channeling through the dense, light-roasted, Bourbon-group bed.

Troubleshooting
sour: Grind finer by ~10μm and raise temp to 94°C. Espresso with washed Bourbon-Pacas at light roast pushes toward aggressive blood orange brightness when under-extracted. The puck is uniform, so channeling is less likely — small grind adjustments are usually sufficient.
thin: Increase dose by 1g or reduce yield to 40g. Light roast espresso at 1:2.4 ratio should produce concentrated TDS — thin output means the shot pulled too long. Check that preinfusion isn't washing out TDS before full pump pressure engages.
Moka Pot 79/100
Grind: 310μm Temp: 100°C Ratio: 1:9.0-1:10.0 Time: 4:00-5:00

Moka pot is well-suited to this bean compared to the Colombia La Colmena, scoring 79/100. The Bourbon-Pacas blend has more straightforward grinding characteristics than a six-variety lot, which means the 310μm medium-fine grind produces a more consistent basket resistance and even heat penetration through the bed. At 100°C pre-boiled water, the near-boiling start compensates for the low 1.5-bar extraction pressure. The blood orange character, under moka pot concentration, transforms into a sharper citrus tartness — not unpleasant but more intense than pour-over. Brown sugar sweetness reads as a darker caramel in this format, because the higher temperature and concentration push Maillard-derived sweetness compounds into a more intense register without the dilution that pour-over ratios provide.

Troubleshooting
sour: Grind finer by ~22μm and verify you're starting with pre-boiled water. Moka pot sourness with light roast almost always traces to slow-heating grounds — cold-start base heats the Bourbon-Pacas bed under steam before the brew cycle, extracting primarily chlorogenic acids.
thin: Increase dose by 1g or reduce water by 15g. Fill the basket fully and level without tamping. Under-filled baskets create head space that reduces pressure consistency and thins the output with this light, less-soluble roast.
strong: Reduce dose by 1g or increase water by 15g. Moka pot concentration with this lot can push blood orange from bright into harsh. Slight ratio dilution preserves the citric character without losing the brown sugar backbone.
French Press 76/100
Grind: 960μm Temp: 96°C Ratio: 1:14.0-1:15.0 Time: 4:00-8:00

French Press at 960μm and 96°C is the highest temperature of all brewers for this bean — it needs to be, because coarse grinding a light roast at 1,500m altitude leaves enormous surface area unexposed. Bourbon and Pacas are medium-density Bourbon-group varieties: not the hardest beans to extract, but at 960μm the particle size means extraction depends heavily on temperature driving diffusion across long distances within the bean cell structure. The extended steep window (4-8 minutes) helps, with Hoffmann's method of waiting an additional 5-8 minutes after pressing allowing remaining grounds to settle. The metal filter passes oils and micro-fines that add a round body underneath the blood orange brightness, partially compensating for the lower extraction efficiency of the coarse grind.

Troubleshooting
sour: Grind finer by ~22μm and raise temp to 97°C. Coarse grinding washed light roast in French Press extracts acids before caramel and stewed plum compounds develop. Extend steep to the full 6-8 minutes before adjusting grind — time helps coarse particles more than in flow-through methods.
thin: Increase dose by 1g or reduce water by 15g. French Press with light roast should produce round body from oils passing through the metal filter — thin output means the ratio needs correcting before anything else. Check that the plunger seal isn't leaking.
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.
