Three varieties in one lot. Red de Miramar is a network of 15-20 smallholders in Oaxaca's Sierra Mixteca, each farming roughly 2 hectares, and their combined harvest blends Bourbon, Typica, and Caturra cherries together. This is not a single-variety showcase — it is a composite, and the chemistry reflects that.
Bourbon and Typica are the two oldest Arabica cultivars in commercial production, both descended from the handful of plants that left Ethiopia centuries ago. Caturra is a natural dwarf mutation of Bourbon. All three belong to the same narrow genetic lineage, but they differ in amino acid concentrations, sugar accumulation rates, and bean density. When blended and roasted together, their Maillard products overlap and layer. Valine from one variety produces methylpropanal — malty. Leucine from another produces 3-methylbutanal — dark chocolate. Isoleucine contributes 2-methylbutanal, which reads as cocoa and almond. The swiss chocolate note on this bean is likely the sum of all three Strecker pathways firing at once.
Raisin is an interesting descriptor because it implies concentrated sweetness. There is no residual sugar in this coffee — roasting consumed it all. The raisin perception comes from a dense cluster of aroma compounds: furanones providing sweetness, melanoidins contributing a dried-fruit richness, and volatile acids giving the impression of preserved fruit. It smells like raisin because the same chemical families are present in actual raisins.
Blood orange points to the acid backbone. Citric and phosphoric acid both exceed their detection thresholds. Phosphoric acid adds the sparkling, sweet-sour brightness that distinguishes blood orange from regular orange — it is effervescent rather than flat. The black tea tannin character comes from chlorogenic acids, which remain largely intact at this light roast level. In darker roasts, those would break down into quinic acid and shift from structured tannin to outright bitterness.
The Chemex earns 96/100 here for the same structural reason it tops the ranking for most washed light roasts: its bonded paper filter removes oils cleanly, and this Mexico washed light has a flavor profile — swiss chocolate, raisin, black tea, blood orange — that benefits enormously from that filtration clarity. The raisin and blood orange notes are delicate aromatics, and any oil interference in the mouthfeel competes with perception of those flavors. The grind at 510μm is 40μm finer than Chemex default, driven by this light roast's lower solubility — Mexico at 1,750m produces dense cherries, but the multi-variety blend (Bourbon, Typica, Caturra) creates slightly more heterogeneous particle behavior than single-variety lots. The 94°C temperature holds full extraction efficiency for washed processing. The 1:15.5 ratio is slightly richer than default, accounting for the lighter roast's reduced dissolved solids per gram.
Troubleshooting
sour: Grind finer by ~22μm and raise temp 1°C. The blood orange acidity in this coffee is citric — the primary acid that exceeds its detection threshold in brewed coffee — and at light roast it dominates when extraction stalls. Moving finer allows the raisin sweetness compounds to dissolve and balance it.
thin: Add 1g coffee or reduce water by 15g; alternatively try a metal filter. The Chemex's thick paper removes oils that contribute to perceived body. This Mexican light roast has moderate melanoidin content, and the filter is doing work against body. Increasing dose compensates for TDS loss.
The V60 handles this multi-variety Mexican washed light well because the slight variation in particle behavior between Bourbon, Typica, and Caturra beans — each with marginally different roasting density profiles — is smoothed out by the V60's swirling pour technique. The swirl during and after bloom ensures all particles get similar water contact, reducing the unevenness that heterogeneous grinds produce. The 460μm grind is 40μm finer than V60 default; only the roast adjustment applies here, because this 1,750m Mexico lot doesn't require an additional altitude grind correction. The 94°C temperature and 1:15.5 ratio are appropriate for a washed light. Expect the black tea note — a dry, tannic quality — to come through cleanly via the V60's paper filter, which removes oils while passing the aromatics driving that attribute.
Troubleshooting
sour: Grind finer by ~22μm and raise temp 1°C. In a V60, blood orange acidity from this Mexican washed light is the first thing to extract and the last to be balanced. If technique is sound but the cup reads sour, the Bourbon and Typica fractions in this blend are under-extracting — both are lower-solubility varieties.
thin: Increase dose by 1g or reduce water by 15g. Light-roast washed Mexico at 1,750m has fewer available dissolved solids than a medium roast of the same beans. The V60's paper filter removes some body-contributing oils; adjusting ratio directly addresses TDS without filter substitution.
The Kalita Wave's even, flat-bottom extraction suits a multi-variety blend where each component — Bourbon, Typica, Caturra — has slightly different particle hardness and dissolution rate. The flat bed ensures every particle receives equal water exposure time, reducing the risk that one variety's fraction over-extracts while another under-extracts. This matters for the raisin and black tea notes in this coffee: dried-fruit and tea-like characteristics develop as extraction progresses, and uneven extraction would produce them inconsistently. The 490μm grind (40μm finer than default) and 3:00–4:00 total brew time allow sufficient contact without the extended steep of an immersion method. At 94°C, the washed processing's clean fermentation and washing of mucilage helps the blood orange character read clearly without competing fermented notes.
Troubleshooting
sour: Grind finer by ~22μm and raise temp 1°C. The Kalita's even extraction is this blend's best friend, but blood orange citric acidity will still dominate if extraction is incomplete. The black tea and raisin notes need the middle extraction phase — finer grind and higher temp pushes the brew into that zone.
thin: Add 1g coffee or reduce water by 15g. Mexico washed lights are noted for light body and clean character — that's origin-typical, not a flaw, but if TDS is genuinely low the cup will taste weak rather than delicate. Increasing dose is more reliable than extending steep on a flow-through brewer.
AeroPress brews Red de Miramar at the standard 85°C with a 360μm grind — 40μm finer than default to account for the light roast's reduced solubility. The finer grind ensures adequate extraction in the short 1–2 minute brew window, and pressure-assisted extraction helps push past what steeping alone would achieve. One advantage of the AeroPress for this multi-variety blend: the enclosed chamber traps aromatic compounds that would escape during an open pour-over bloom, which tends to intensify the perception of blood orange, raisin, and dried-fruit character. The 1:12.5 ratio produces a concentrated cup that makes the most of the increased surface area and sealed extraction environment. Press steadily — light-roast washed coffee extracts efficiently under pressure, so consistent technique keeps the cup balanced.
Troubleshooting
sour: Grind finer by ~22μm and raise temp 1°C to 86°C. At 85°C, the swiss chocolate and raisin compounds in this Mexican washed light extract more slowly than the blood orange acids. Sourness is the predictable result if the brew time isn't extended or grind size reduced.
thin: Add 1g coffee or reduce water by 15g. The AeroPress 1:12.5 ratio is already quite concentrated. If the cup reads thin at this setting, the multi-variety blend is under-extracting across all fractions. Check that 360μm grind is accurate — coarser-than-set grinds are a common cause.
The Clever Dripper's immersion phase is well-suited to the Bourbon-Typica-Caturra variety blend in this Mexican washed light, because all three varieties steep together with equal water access — no particle gets preferential treatment based on position in a cone. During the 3:00–4:00 steep at 490μm and 94°C, the brighter acids extract first (as they always do), followed by the raisin and swiss chocolate sweetness in the middle of extraction. The black tea character — a dry, structured quality common in Mexican washed coffees — comes through cleanly because the paper filter on drain removes oils that would muddy it. The 1:15.5 ratio is appropriate; the Clever's controlled drain means total contact time is predictable, and the recipe accounts for this with a standard steep window.
Troubleshooting
sour: Grind finer by ~22μm and raise temp 1°C. Sourness in the Clever indicates the steep phase completed with only acids extracted. For this Mexican blend, the black tea and raisin notes require reaching the middle extraction phase — finer grind ensures more surface area during the immersion.
thin: Add 1g coffee or reduce water by 15g. If immersion contact time is adequate but TDS is still low, the Caturra and Typica fractions in the blend may be providing dilution relative to their extraction potential. Increasing dose addresses the concentration directly.
This Mexican washed light — Bourbon, Typica, Caturra at 1,750m — presents as a genuinely interesting espresso candidate, particularly because the blood orange and black tea notes concentrate well under pressure. The recipe uses light-roast espresso parameters: a longer ratio (1:2.4) and preinfusion. The 210μm grind is 40μm finer than default, driven by light roast density. Caturra is notably more extraction-resistant than Typica in this blend — its dwarf plant structure produces denser beans at altitude — which is part of why the longer ratio is appropriate. Expect the blood orange note to read as an intensely citric, almost acidic brightness in the shot, with swiss chocolate in the body and a black tea-like finish that's unusual and distinctive for Mexican espresso.
Troubleshooting
sour: Grind finer by ~10μm and raise temp 1°C. Light-roast espresso with a multi-variety blend is particularly sourness-prone because the varieties extract at different rates under pressure. Start with conservative 5–10μm changes — the Caturra fraction responds more sharply to grind changes than the Typica.
thin: Increase dose by 1g or reduce yield by 15g. The espresso_light recipe's longer ratio compensates for light-roast extraction resistance, but at the cost of some concentration. If TDS reads thin, pull back the ratio slightly rather than grinding finer — both reach the same extraction, but ratio adjustment is more controllable.
Moka pot extraction concentrates this Mexican washed light's flavor profile, making the swiss chocolate note forward and the blood orange read as a sharp citric brightness rather than the delicate top note it is in a Chemex. The standard moka temp of 100°C applies here, and the 310μm grind is 40μm finer than default. The multi-variety blend (Bourbon, Typica, Caturra) means the moka pot's relatively uncontrolled extraction environment will produce some inter-variety unevenness — use pre-boiled water and remove from heat immediately when sputtering to minimize this.
Troubleshooting
sour: Grind finer by ~22μm and raise temp 1°C. The moka pot's heat path can under-extract light roast if the water moves too quickly through a coarse bed. Blood orange acidity will dominate if chocolate and raisin compounds don't dissolve. Finer grind slows flow and increases extraction contact.
thin: Add 1g coffee or reduce water by 15g. Moka pots are concentration-limited by basket volume. If the cup reads thin, increasing dose within the basket is the primary lever. Mexican washed lights are naturally lighter-bodied than Central African or Indonesian origins, so some perceived thinness is expected.
strong: Reduce dose by 1g or add 15g water. Moka pot brews concentrate naturally; if the blood orange and black tea read as harsh or astringent, TDS is too high. Diluting with hot water after brewing is a valid adjustment — it's essentially the bypass technique used in competition AeroPress.
French Press delivers this Mexican washed light without oil filtration — the metal mesh passes oils into the cup, adding mouthfeel that this origin's profile doesn't naturally carry in abundance. Mexico washed light is known for light body and delicate character; the French press partially compensates for that by contributing oil-based texture. The raisin note — a dried-fruit aromatic — reads more richly in a French press than in a Chemex because the unfiltered oils enhance aromatic perception. The 960μm grind is standard for French press, and the 4:00–8:00 window allows the dense 1,750m beans to extract at the coarser setting. The black tea character reads as a broader, less defined dry quality in the full-immersion brew rather than the crisp finish it shows in filtered methods.
Troubleshooting
sour: Grind finer by ~22μm and raise temp 1°C. Blood orange citric acidity is the first flavor out of this Mexican washed light. In a French press, the coarse grind limits extraction speed, and sour results usually indicate the immersion time wasn't long enough for the raisin and chocolate compounds to follow.
thin: Add 1g coffee or reduce water by 15g. Mexico washed light is inherently lean in body compared to Indonesian or Brazilian origins. French press oils add some mouthfeel, but if TDS is genuinely low, ratio adjustment is required. The 1:14.5 recipe is already fairly rich — moving to 1:13 is the next step.
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.
