Growing coffee for espresso doesn't change what's in the bean — it changes what the roaster decides to do with it. At 1,750 meters in Ozolotepec, nine Zapotec smallholder farms produce coffee at the upper end of Oaxaca's altitude range. Higher altitude means slower cherry development, more concentrated organic acids and sugar precursors in the seed, and — all else equal — higher extraction yield potential. The medium-light roast is positioned for espresso: slightly more development than a filter-oriented light roast, trading some of the brightest citric acid character for additional Maillard complexity and solubility. Under espresso pressure, extraction happens in 25-35 seconds, moving through the acid phase, the caramel-sweetness phase, and the beginning of the dry-distillate phase very quickly. A roast that's too light can leave excess chlorogenic acids — the primary bitter/astringent compound in underdeveloped coffee — intact, which extract fast under pressure and dominate the cup. Lemon and lime confirm that citric acid is still present and active. The cherry note is malic — crisp, round, stone-fruit — surviving the medium-light development. Panela, the unrefined cane sugar, is the Maillard and caramelization story: sucrose is nearly 100% consumed during roasting, yet perceived sweetness increases through the light-medium range. The panela register comes from caramelization products — furanones, maltol — that create olfactory sweetness rather than actual residual sugar. Typica roasts in the fast-roast group (first crack around 7:30 minutes), while Bourbon is slower (8:30-9:00 minutes). Mixed lots of both require careful heat management, as the varieties respond differently to the same roast profile — a practical challenge for the roaster, and a source of textural complexity in the cup.
Hario V60-02 88/100
Grind: 450μm Temp: 93°C Ratio: 1:15.3-1:16.3 Time: 2:30-3:30

The medium-light roast on this Oaxacan Typica-Bourbon blend lands at a solubility level that splits cleanly between filter-optimized and espresso-ready territory. The 1°C temperature reduction to 93°C addresses both the roast's slightly higher CGA intact fraction and the altitude ceiling — at 1,750 meters, extraction capacity is already elevated, so you don't need the full heat ceiling. The 50μm finer grind (partly from roast, partly from altitude correction) compensates for the denser Bourbon-influenced bean structure and maintains sufficient residence time through the V60's faster conical drain. The 1:15.3-16.3 ratio sits 0.5 points leaner than default to concentrate the panela sweetness — with Maillard caramelization products driving the perceived sweetness rather than residual sugar, a slightly stronger cup brings that register into focus rather than diluting it into background.

Troubleshooting
sour: Grind finer by ~22μm and raise temp to 94°C. At medium-light roast, citric and malic acids from the lemon-lime notes extract before the slower panela sweetness arrives. Finer grind closes surface area gaps; the extra degree pushes extraction deeper into the caramelization band.
thin: Add 1g more coffee or reduce water by 15g to tighten the ratio. This Oaxacan lot has moderate density — it won't self-concentrate. A metal filter swap also recovers the oils that washed processing keeps lean, adding tactile weight to an otherwise clean cup.
Kalita Wave 185 88/100
Grind: 480μm Temp: 93°C Ratio: 1:16.3-1:17.3 Time: 3:00-4:00

The Kalita's flat-bottom design distributes water across a wider bed footprint than the V60's cone, meaning each pulse contacts more of the 480μm-ground bed at once. This forgiveness on pour technique is actually an advantage for a medium-light roast that needs complete extraction to get past the early acid phase and into the panela the sweetness range. The 93°C target matches the V60 setting — same altitude ceiling and roast penalty — but the Wave's slightly longer recommended brew time (3:00-4:00 vs. V60's shorter window) gives the slower-extracting caramelization products additional contact. Bourbon's tendency toward fuller body at the same extraction yield as Typica shows up here: the flat-bed even extraction should produce a slightly more textured cup than a V60 if your technique is aggressive on the V60.

Troubleshooting
sour: Grind finer by ~22μm and raise temp to 94°C. The flat bed on the Wave can channel if pours are uneven, leaving some grounds under-extracted — all lemon-lime, no panela. Confirm the bed is fully saturated on each pulse before adding more water.
thin: Add 1g dose or reduce water by 15g. The Wave's perforated flat base means water doesn't linger as long as in the V60's cone. If ratio already feels lean, don't pour on the filter walls — concentrate flow through the bed to maximize contact.
Chemex 6-Cup 86/100
Grind: 500μm Temp: 93°C Ratio: 1:15.3-1:16.3 Time: 3:30-4:30

The Chemex's 20-30% thicker filter removes oils more aggressively than any other paper brewer, which matters here because washed processing has already done the fruit-layer removal work. What's left is a very clean acid-and-sweetness signal — and the Chemex's filtration preserves that clarity without muddying it with lipids. The 93°C temperature and 500μm grind are calibrated to the medium-light roast: slightly finer than a typical medium to compensate for lower solubility, slightly cooler than boiling to avoid over-extracting the still-abundant chlorogenic acids. The 1:15.3-16.3 ratio leans stronger than a typical filter ratio to ensure the panela sweetness — an aroma-mediated Maillard signal — has enough concentration to register through the Chemex's aggressive filtration.

Troubleshooting
sour: Grind finer by ~22μm and raise to 94°C. The Chemex's extended drawdown at 500μm should extract fully, but this medium-light roast's intact CGAs need extra surface contact. The thick filter slows flow — use that residence time by grinding tighter.
thin: Increase dose by 1g or cut water by 15g. Alternatively, switch to a Chemex metal filter — the standard bonded filter strips oils that compensate for TDS. With washed Oaxacan coffee already lean on lipids, paper filtration can push body below threshold.
AeroPress 85/100
Grind: 350μm Temp: 84°C Ratio: 1:12.3-1:13.3 Time: 1:00-2:00

The AeroPress recipe here uses 84°C — a meaningful 9°C drop from the V60 setting, driven by the AeroPress's pressure assist and shorter brew window rather than a temperature penalty. At medium-light roast, this matters: pressure mechanically extracts compounds that would need higher temperature to dissolve at atmospheric conditions, compensating for the temperature reduction. The 350μm grind is considerably finer than typical V60 territory and pulls the extraction faster under manual pressure. The 1:12.3-13.3 ratio produces a more concentrated cup than the filter options, which concentrates the panela and cherry notes that might read thin at filter strength. The 1-2 minute window is achievable at this grind — don't overextend the steep or the citric acids dominate before the Maillard sweetness can follow.

Troubleshooting
sour: Grind finer by ~22μm and raise to 85°C. The AeroPress's short brew window means lemon-lime acids can dominate if extraction is rushed. Add 15-20 seconds of steep time and ensure full saturation during bloom before pressing.
thin: Add 1g dose or cut water by 15g — already at 1:12, so a small dose change has more leverage here than on filter ratios. The metal filter option recovers oils and adds mouthfeel without changing the fundamental acid-sweetness character of this Oaxacan lot.
Clever Dripper 85/100
Grind: 480μm Temp: 93°C Ratio: 1:15.3-1:16.3 Time: 3:00-4:00

The Clever Dripper is a hybrid: immersion steep followed by drip drawdown through a paper filter. That combination is well-suited to this medium-light roast because the immersion phase gives the slower-extracting caramelization compounds — the panela register — time to diffuse into solution before the paper filter's drawdown clarifies the cup. The 93°C setting matches the V60 and Kalita; the 480μm grind is slightly coarser than the V60's 450μm because the immersion steep compensates for the reduced surface area. The 1:15.3-16.3 ratio is identical to the V60. The 3:00-4:00 window should be treated as immersion time before releasing — don't release early or the cup skews citric.

Troubleshooting
sour: Grind finer by ~22μm and raise temp to 94°C. Extend steep to 4 minutes before releasing the valve — this medium-light roast's lemon-lime acids extract quickly, and the Clever's immersion phase needs full time to develop the slower panela sweetness.
thin: Add 1g dose or cut water by 15g. If TDS still reads lean, try a metal filter in the Clever — recovers oils the paper removes. With washed processing already stripping fruit-layer body, paper filtration can tip the balance toward tea-like thinness.
Espresso 83/100
Grind: 200μm Temp: 92°C Ratio: 1:1.3-1:2.3 Time: 0:25-0:30

This lot is labeled Single Origin Espresso, meaning the medium-light roast was calibrated specifically for pressurized extraction — with slightly more Maillard development than a filter roast would have, trading some of the brightest citric character for solubility under 9-bar conditions. The 92°C temperature is 1°C below default, acknowledging that espresso's concentrated extraction amplifies every compound: even small temperature overages on a citric-forward medium-light roast push sourness quickly. The 200μm grind and 1:1.3-2.3 ratio are standard espresso parameters adjusted for the medium-light roast's denser, less-soluble bean structure. The 25-30 second shot window is narrow — watch flow rate for channeling signals, which appear as unexpected speed in the early pour.

Troubleshooting
sour: Grind finer by ~10μm and raise to 93°C. Espresso extraction happens in 25-30 seconds — if the shot moves fast, the citric phase dominates and the panela sweetness never develops. Finer grind slows flow, extending the extraction window into the caramelization band.
thin: Add 1g dose or cut output by 15g to tighten the ratio. Unlike filter methods, there's no metal filter option here. Ratio is the primary TDS lever at espresso. Don't confuse thin with sour — taste carefully before adjusting, as the corrections are opposite.
Moka Pot 81/100
Grind: 300μm Temp: 93°C Ratio: 1:9.3-1:10.3 Time: 4:00-5:00

Moka pot operates at ~1.5 bar — far below espresso's 9 bar — so its 'pressure extraction' designation is more about concentration than true pressurized compound extraction. The recipe's 93°C pre-boiled water recommendation is critical here: starting with cold water lets the grounds sit in rising steam before extraction begins, effectively cooking them and extracting unpleasant bitter compounds from this medium-light roast's intact CGAs. The 300μm grind is medium-fine (coarser than espresso, finer than V60) and the 1:9.3-10.3 ratio produces a concentrated output designed for dilution or direct drinking in small volumes. The lemon, lime, and panela notes concentrate predictably under this pressure. Don't tamp the basket — this Oaxacan lot's density already resists flow enough.

Troubleshooting
sour: Grind finer by ~22μm and ensure water is pre-boiled before filling the base. With this medium-light roast's abundant citric acids, starting with cold water causes prolonged low-temperature extraction that extracts acids first and stops. Pre-boiled water skips the ramp phase.
strong: Reduce dose by 1g or add 15g more water to the base. Moka pot concentrates this medium-light Oaxacan lot quickly — the panela and cherry notes intensify fast. Overly strong output turns the citric profile harsh. Dilute or adjust ratio before changing grind.
French Press 79/100
Grind: 950μm Temp: 93°C Ratio: 1:14.3-1:15.3 Time: 4:00-8:00

French Press is the lowest-ranked brewer for this medium-light espresso-designated lot, and the recipe reflects why: the 93°C setting (3°C below default) and 950μm coarse grind are trying to limit over-extraction of the citric and malic acids that go fine without metal-filter body to balance them. The washed processing means there's no natural-process fruit body in reserve — what the bean delivers is clean acid and Maillard sweetness, and the French press's immersion method doesn't add clarity. The coarser grind slows acid extraction slightly. The 4:00-8:00 window is intentionally wide: steep at 4 minutes for a brighter, more citric expression; extend toward 8 minutes to let the slower caramelization compounds develop more. Don't press if you want clarity — let grounds settle, pour from the top.

Troubleshooting
sour: Grind finer by ~22μm and extend steep to 6-8 minutes. The coarse French press grind already limits surface area. This Oaxacan lot's washed, medium-light roast profile has abundant citric acid — extending steep time allows slower Maillard compounds to catch up and balance.
thin: Add 1g dose or reduce water by 15g. French press with washed coffee at medium-light roast won't build body through oils alone — the washed process and metal mesh filter contribute differently. Stronger ratio is the most direct lever for TDS.
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.
