The Dota Medium and Dota Dark are the same coffee at different points on the roast curve. Comparing them is a direct window into what roast degree actually does to a bean's chemistry — and why medium occupies different territory than light or dark.
At 1,707 meters, this is high-end Costa Rica altitude. Washed processing means the bean's flavor is driven by terroir and variety rather than fermentation or fruit contact. Caturra and Catuai, both Bourbon-lineage dwarf varieties, contribute bright citric acidity and medium body under light roasting. Medium development changes the balance.
Between first crack and the medium drop point, organic acid dynamics shift. Chlorogenic acids — the primary bitterness and astringency source in light coffee — continue to decompose into quinic acid, but medium roasting stops before phenylindane formation becomes aggressive (that accelerates at dark roast). Citric and malic acids degrade partially: some brightness remains, but less than at light. Maillard reaction products build further, generating the melanoidins that add body and texture. According to the roasting chemistry, sweetness follows a bell curve — too light produces sour/grassy, optimal produces sweet/complex, too dark produces bitter/ashen. Medium aims to land in the sweet spot.
This lot arrives with no flavor notes in the record, which is worth acknowledging directly: medium-roasted washed Costa Rica at this altitude typically expresses chocolate, brown sugar, and mild stone fruit — the Maillard compounds and residual citric acid that survive medium development. The absence of published tasting notes just means the chemistry has to do the talking. What medium roasting preserves from Dota's terroir is the structured body that 1,707-meter altitude and washed clarity deliver, without either the brightness of light or the melanoidin saturation of dark.
This medium Costa Rican coffee scores 88 on the AeroPress — one of its strongest brewer matches. The grind is 370μm, 30μm finer than the AeroPress default, because the altitude-driven bean density requires more surface area for extraction in the short 1:00–2:00 window. Temperature is 83°C, dropped 2°C from the AeroPress's standard 85°C, since the medium roast's greater solubility means less heat is needed to reach full extraction. This cooler temperature also keeps the dark chocolate richness smooth and sweet rather than edging into bitterness. The concentrated 1:12.5–1:13.5 ratio delivers an intense, syrupy cup where the cherry sweetness and orange brightness are amplified. The AeroPress is especially effective with medium roasts — the combination of immersion, pressure, and paper filtration produces a clean, rich cup.
Troubleshooting
bitter: Grind coarser by ~22μm and drop temp to 82°C. At 83°C with pressure assist, the Dota Medium's elevated solubility extracts faster than a light roast at the same conditions. If grind is already at the tight end of 370μm, over-extraction into dry distillates happens quickly. Coarsen first, then adjust temp.
thin: Increase dose to 15g or reduce water by 15g. The AeroPress at 1:12.3–13.3 should produce a concentrated cup on this 1,707m Caturra/Catuai. If thin, water likely bypassed grounds during the steep — ensure all grounds are fully submerged after adding water before beginning the timer.
The Clever Dripper scores 88/100 for this medium Costa Rican coffee. The grind is 500μm — 30μm finer than the Clever default — adjusted for the altitude-driven density of these Caturra and Catuai beans. Temperature drops to 92°C, 2°C below standard, because the medium roast has enough solubility that lower heat prevents over-extraction while still fully developing the dark chocolate, cherry, and orange character during the 3:00–4:00 immersion. The Clever's full-immersion design provides consistent contact between water and grounds, which is ideal for medium roasts — every particle extracts at the same rate, producing a balanced, predictable cup. The 1:15.5–1:16.5 ratio delivers a clean, sweet brew after the paper-filtered drawdown, with chocolate sweetness and fruit brightness in harmony.
Troubleshooting
bitter: Grind coarser by ~22μm and reduce steep time toward 3 minutes. The Clever's immersion at 92°C extracts medium-roast quinic acid efficiently — if steep runs past 4 minutes or grind was finer than 500μm, bitter compounds accumulate in the cup. Cutting steep time is the fastest correction.
thin: Increase dose to 19g or reduce water by 15g. The Clever's paper filter removes oils that contribute perceived body — while this keeps the cup clean, Caturra/Catuai's naturally medium body isn't supplemented by oil contribution. Tighter dose-to-water ratio compensates directly.
Scoring 87, the V60 is a strong match for this medium Costa Rican coffee. The grind sits at 470μm — 30μm finer than the V60 default — to compensate for the altitude-driven density of these Caturra and Catuai beans. Temperature drops to 92°C, 2°C below standard, because the medium roast has already broken down the bean structure during roasting, increasing solubility. This lower temperature prevents the dark chocolate notes from becoming bitter while still pulling the cherry and orange brightness through the fast 2:30–3:30 drawdown. The V60's cone design and thin filter produce a cup that emphasizes clarity and highlights the interplay between the chocolate richness and the fruit acidity. The 1:15.5–1:16.5 ratio provides balanced extraction without washing out the flavor.
Troubleshooting
sour: Grind finer by ~22μm and raise temp to 93°C. The V60 at 470μm can still underextract if pour technique was uneven — channeling through the conical bed means some of this high-altitude Caturra/Catuai's solubles never fully dissolved. Sour on a medium roast usually points to evenness rather than just grind size.
thin: Increase dose to 20g or reduce water by 15g. Thin is unusual for a 1,707m Caturra/Catuai with ample solubles. If the cup is thin, the likely cause is channeling through the V60 bed — confirm that bloom fully wetted all grounds before the main pour.
The Kalita Wave scores 87 with this medium Costa Rican coffee, offering a reliable and forgiving brew. The grind is 500μm — 30μm finer than the Wave default — adjusted for the altitude-driven density of these beans. Temperature drops to 92°C, 2°C below standard, because the medium roast's increased solubility means less heat is needed to hit the extraction sweet spot. The Wave's flat-bottom filter and restricted flow rate produce an even extraction bed that naturally balances the dark chocolate depth with the cherry and orange brightness across the 3:00–4:00 brew window. The 1:16.5–1:17.5 ratio gives generous water volume for thorough, even extraction. This is a forgiving recipe — the Wave smooths out minor technique variations, making it a great everyday brewer for this balanced, approachable coffee.
Troubleshooting
sour: Grind finer by ~22μm and raise temp by 1°C. On the Kalita's flat bed, sour from medium Costa Rica usually indicates uneven pulse pouring — if early pulses ran too fast, water ran off the corrugated walls before contacting all grounds. Finer grind and more deliberate pacing correct both issues.
thin: Add 1g dose or remove 15g water. Caturra and Catuai at 1,707m have high density, so thin is usually a ratio issue rather than a grind issue. Tightening toward 1:16.0 resolves it without needing to change grind size or technique.
This medium-roast Costa Rican blend of Caturra and Catuai scores 85 on the Chemex. The grind is set to 520μm — 30μm finer than the Chemex default — because the high-altitude growing conditions produce denser beans that need more surface area for proper extraction, even at medium roast development. Temperature drops to 92°C, 2°C below the Chemex default, since the medium roast has already developed more soluble compounds during roasting and needs slightly less extraction energy to avoid tipping into bitterness. The Chemex's thick paper filter delivers a clean cup where the dark chocolate richness and cherry sweetness present with clarity. The orange note adds a bright, citrusy lift to the finish. The standard 1:15.5–1:16.5 ratio gives this well-balanced coffee the water volume it needs without over-diluting the chocolate base.
Troubleshooting
thin: Increase dose to 29g or reduce water by 15g. The Chemex's heavy paper removes oils that carry medium-roast body — the Dota's key advantage over a light roast. Adding dose compensates directly. A metal filter insert is theoretically possible but sacrifices what makes the Chemex the right brewer choice here.
sour: Grind finer by ~22μm and raise temp to 93°C. Sour on a medium-roast 1,707m Costa Rica is unusual — the roast should have converted most harsh CGAs. If sour persists, water is channeling around the thick filter bed. Confirm the multi-fold filter side faces the pour spout.
This medium Costa Rican coffee scores 85 as espresso, benefiting from the roast level's natural balance of solubility and flavor complexity. The grind drops to 220μm — 30μm finer than the espresso default — because the altitude-driven density creates tighter bean structures that need more surface area under pressure. Temperature is 91°C, 2°C below the espresso standard, since the medium roast's increased solubility means less heat is needed. This prevents the dark chocolate from becoming ashy while preserving the cherry and orange brightness under espresso's intense extraction. The 1:1.5–1:2.5 ratio sits in the classic espresso range, producing a balanced shot with substantial body. Aim for 25–30 seconds. Expect rich dark chocolate sweetness, concentrated cherry fruit, and a clean orange citrus finish.
Troubleshooting
sour: Grind finer by ~10μm and raise temp to 92°C. A sour shot on medium Costa Rica usually means channeling — the longer 38g output gives more time for channels to form in the puck. Check distribution before tamping, then grind finer if the shot still runs fast and finishes sour.
bitter: Grind coarser by ~10μm and drop temp to 90°C. Medium-roast Caturra/Catuai at 1,707m has high solubility — at 220μm with 9-bar pressure, over-extraction happens faster than with a light roast. The longer output ratio already compensates somewhat, but coarsening grind directly reduces surface area to slow extraction.
The Moka pot scores 83 with this medium Costa Rican coffee — a natural pairing since medium roasts thrive in the Moka pot's concentrated, high-heat extraction. The grind is 320μm, 30μm finer than the default, to account for the altitude-driven density of these beans. Temperature drops to 98°C, 2°C below the standard 100°C, providing a slight buffer against the aggressive heat that can push medium roasts past their sweetness window. Pre-heat the water and remove the pot from heat at the first sign of sputtering. The concentrated 1:9.5–1:10.5 ratio produces a rich, intense brew where the dark chocolate becomes almost fudge-like and the cherry sweetness concentrates into a deep, jammy note. The orange brightness provides a welcome lift that keeps the cup from feeling heavy.
Troubleshooting
sour: Grind finer by ~22μm and confirm pre-boiled water is used. Sour on medium Costa Rica in the moka pot typically means channeling — the medium-fine bed at 320μm must be evenly distributed without tamping. Any uneven distribution creates fast channels where water bypasses grounds entirely.
strong: Reduce dose by 1g. High-altitude Caturra/Catuai at medium roast extracts efficiently at moka pot pressure — at 18g in a standard basket, the result can push above comfortable TDS. Reducing dose slightly opens the effective ratio toward 1:10.5 without changing any other variable.
The French Press scores 82 with this medium Costa Rican coffee, and the pairing plays to both the brewer's and the roast level's strengths. The grind is 970μm, 30μm finer than the default, adjusted for the altitude-driven density of these beans. Temperature drops to 94°C, 2°C below the French Press standard of 96°C, because the medium roast's greater solubility means full extraction happens at lower heat. This prevents the long 4:00–8:00 steep from pushing the dark chocolate into bitterness. The metal mesh filter lets oils through, adding a rich, velvety body that complements the chocolate character beautifully. The 1:14.5–1:15.5 ratio concentrates the brew enough that the cherry and orange notes still register against the heavier mouthfeel. Medium roasts are the French Press sweet spot — expect a full-bodied, satisfying cup.
Troubleshooting
strong: Reduce dose by 1g or add 15g water. At 94°C with 1:14.5–15.5 and high-altitude Caturra/Catuai solubility, the French press can over-extract in concentration if grind is tighter than intended. Reduce dose first — widening the ratio dilutes all compounds including bitter ones proportionally.
bitter: Grind coarser by ~22μm and apply Hoffmann's method: press at 4 minutes, then wait 5–8 more minutes before pouring to let fines settle. Medium roast quinic acid accumulates during long French press steeps. Coarser grind slows extraction; the extended settle prevents fines from continuing to extract in the cup.
This medium Costa Rican coffee scores 78 as cold brew, and the roast level's developed sweetness translates well to cold extraction. The grind is 870μm — 30μm finer than the cold brew default — because the altitude-driven bean density requires more surface area even in the long 12–18 hour steep. Temperature drops to 2°C, 2°C below standard, which slows extraction further and produces a smoother, less acidic concentrate. Cold water naturally under-extracts lighter, more volatile compounds, but the medium roast's dark chocolate and cherry notes are robust enough to survive the process. The 1:6.5–1:7.5 ratio produces a concentrate you can dilute to taste. Expect a smooth, chocolate-forward cold brew with a subtle cherry sweetness and a whisper of orange in the finish — the bright citrus will be muted but still present as a gentle lift.
Troubleshooting
flat: Grind finer by ~22μm and steep closer to 5°C rather than the coldest fridge temperature. Medium-roast Caturra/Catuai has fewer volatiles than a light roast — flat cold brew often reflects the roast's inherent aromatic reduction. Slightly warmer temperature increases extraction of the remaining caramel and chocolate compounds.
thin: Increase dose by ~8g to 88g or reduce water to 500g. The 1:6.5–7.5 concentrate ratio is already aggressive, but 1,707m Caturra/Catuai extracts less efficiently at cold temperatures. Tighter concentrate ratio compensates — dilute 1:1 before serving to reach drinkable strength.
