Key Takeaways

El Salvador (p.166)

  • ~20,000 cultivators with medium-sized plantations; 60%+ Bourbon
  • Developed Pacas (1949, natural Bourbon mutation) and Pacamara (1958, Pacas × Maragogype, with French/CIRAD collaboration) locally
  • Shade-grown predominates; plays an important anti-deforestation and soil-erosion role
  • The Consejo Salvadoreño del Café (CSC) promotes quality, volcanic soil, and the Bourbon variety
  • Infrastructure and traceability are noted as good; other growing regions beyond Apaneca-Ilamatepec: El Bálsamo-Quezaltepeque, Tecapa-Chinameca, Cacahuatique, Alotepec-Metapán
  • Cup profile: full body, creamy, soft acidity, balanced
  • Harvest: November–March; both wet and dry drying methods used

Altitude and Flavour (p.137)

Higher altitude → slower maturation → denser beans → more acidity, depth, and complexity.

AltitudeCup character
1,500–2,000 mFloral, spiced, fruity, acid — maximum complexity
1,200–1,500 mAcidity develops, more aromas
1,000–1,200 mScarce acidity, round
800–1,000 mAcid, low complexity

Kaiserblick’s farms (1,200–1,800 masl) sit in the top two bands. See Apaneca-Ilamatepec.

Variety Profiles (p.138–139, 168–169)

Detailed profiles for varieties Kaiserblick grows — see Coffee Varieties for full agronomic detail. Key highlights:

  • Bourbon: benchmark variety; fine, light body, smooth. Red for espresso, yellow for filter/cold brew.
  • Pacas: Bourbon mutation (El Salvador, 1949); smaller, better disease resistance; similar cup to Bourbon.
  • Pacamara: Pacas × Maragogype (El Salvador, 1958, CIRAD); large beans, vigorous; complex aromatics and good acidity at high altitude; best for filter.
  • Geisha: SW Ethiopia origin; introduced Panama 1963; floral, tea body, citrus and berries, very refined; 1,500 m+; filter only; premium pricing.
  • Typica: oldest arabica; complex aromatics; low productivity; parent of Bourbon.
  • Caturra: Bourbon mutation (Brazil, 1937); smaller shrub; better productivity; slightly inferior cup.
  • Catuai: Mundo Novo × Caturra (Brazil, 1968); wind resistant; standard quality; espresso.
  • Catimor: Híbrido de Timor × Caturra (Portugal); roya resistant; productive; cup quality debatable.

Processing Methods (p.142–145)

Full treatment of the five main methods — see Coffee Processing. Key distinctions:

  • Natural: whole cherries dried; intense fruit, full body, winey risk. Brazil, Ethiopia, Panama.
  • Washed: depulped + fermented 6–72h; clean, bright, pronounced acidity (pH <5). El Salvador, Kenya, Colombia.
  • Honey process: Central American variant of pulped natural; grades by mucilage left (White/Yellow/Red/Black); intermediate profile.
  • Pulped natural: Brazilian 1990s; wet selection + dry fermentation; intermediate.
  • Giling basah: Indonesia only; wet-hulled; very full body, very low acidity.

El Salvador primarily uses washed processing, consistent with the region’s climate and Kaiserblick’s operations.

Roasting (p.112–120)

Full treatment — see Roasting. Key principles:

  • Roast profile ≠ roast level: two coffees with identical start and end temperature but different temperature curves will taste completely different. The profile is the path, not the endpoint.
  • Development time ratio (DTR): time from first crack to drop, as % of total roast. A key quality variable.
  • Light roast: acidity (citric, malic) peaks at light roast then declines. Chlorogenic acids (polyphenols) break down into astringent quinic and caffeic acids as roast darkens. Only light roast preserves origin character.
  • Caffeine: stable across roast levels (~10% loss maximum); perception of “stronger” dark coffee is a bitterness illusion.
  • Filter vs. espresso roast: filter benefits from lighter roast (long extraction amplifies acidity/subtlety); espresso benefits from slightly darker (short extraction amplifies acidity from light roast).
  • Central American coffees: “aromatic complexity and acidity — the best lots don’t need to be blended.” Suited to single-origin filter.

Single Origin vs. Blend (p.118)

  • Single origin: unique character; reveals terroir, variety, processing, producer work. Ideal for filter methods.
  • Blend: consistency and accessibility; compensates for espresso’s extraction variability. Max 3–4 origins.
  • The strictest single-origin definition (one farm + one variety) is agronomically debatable — mixing varieties from different altitudes on one farm is rational (disease risk diversification, flavour complexity).

Cupping Protocol (p.124–125)

Standardised evaluation used by producers, green buyers, and roasters — see Cupping (Cata). Parameters: 12g, filter grind, 92–95°C water, 20cl bowl, 4-minute infusion. Evaluated from dry aroma through multiple tasting temperatures. SCA score 80+ = specialty. The SCA/WCR Flavor Wheel provides shared vocabulary.

Green Coffee Selection and Export (p.146–147)

Post-drying dry milling covers four selection stages: density, size calibration, automated colour sorting, and manual finishing. Export packaging: jute sacks (commodity), vacuum packs (premium/microlots), GrainPro multilayer bags (best aromatic preservation). See Green Coffee Selection and Export Preparation.

Freshness: green coffee is a seasonal fresh product. “Past crop” (old harvest) beans develop woody taste and loss of acidity. A coffee can turn past crop through poor drying, bad storage, long transport, or delay before roasting — not only through age.

Specialty Coffee Market Context (p.17–21)

  • Specialty coffee: ~1% of world production (c.2016 estimate); SCA score 80+
  • Supply chain roles: producer → green buyer (cupping, lot selection, purchasing) → roaster (profile development) → barista (extraction)
  • Cup of Excellence: national competition created 1999; best lots auctioned online; guarantees quality and gives producers recognition. El Salvador participates. See Apaneca-Ilamatepec (2025 CoE results).

Organic Coffee Note (p.137)

The book states that from a taste perspective, organic certification does not modify cup quality. In Ethiopia, many small farmers are effectively organic without certification simply because inputs are too expensive. This is a stated opinion; it is contested in specialty coffee circles where farming practice is increasingly linked to terroir expression and soil health. See Organic Farming.
