kofio-co-crawl.md— Source summary; platform mechanics, roaster list, pricing benchmarks, El Salvador gap, B2B arm, strategic relevancekofio.md— Platform concept page; business model, product structure, retail pricing table, ES underrepresentation, relevance to Kaiserblick export strategy
Pages updated (3):
green-coffee-trading.md— Added “European Specialty Retail Pricing” section (retail price tiers, back-calculation to green price, ES market gap); added kofio and main-lane-coffee-roasters to related pagescoffee-processing.md— Added Co-fermented definition to Anaerobic Fermentation section; added Kofio to sources and related pagesindex.md— Added kofio to Trade section; added kofio-co-crawl to Sources section
Key insights:
- El Salvador has only 1 listing on Kofio vs. 7 Guatemala, 4 Honduras — a clear market gap
- European specialty retail: €72–124/kg; implies viable green price range of ~€16–25/kg for Kaiserblick lots
- Co-fermented coffee is a formal commercial category on European platforms, not a niche curiosity
Open questions flagged:
- Total roaster count on Kofio (crawl captured ~12; actual number likely much higher)
- Whether Kofio accepts roasters based outside Europe
- Germany and France shipping rates not captured in this crawl

Key connections to existing wiki:
- Sweetness crossmodal mechanism links Sensory Science ↔ Cupping (Cata) ↔ Coffee Taster’s Flavor Wheel — resolves the long-standing question of why coffee “seems sweet” without dissolved sugars
- Halo effect / 90% correlation in cupping scores is the scientific explanation for why Cupping (Cata) calibration sessions (multiple cuppers together) are essential for Kaiserblick’s quality control
- “Juicy” acidity as a price premium driver directly validates Apaneca-Ilamatepec’s high altitude as a commercial asset — links Sensory Attributes and Value ↔ Apaneca-Ilamatepec ↔ Green Coffee Trading
- Crossmodal effects (cup color, shape) are actionable for the Kaiserblick Specialty Coffee café and Experiences product design
- Bitterness chemistry correction in Roasting aligns with the handbook’s explanation of why dark roasts taste harsher and more bitter (phenylindanes from over-roasting)
- Pre-shipment/arrival sampling guidance directly applicable to Leopold Robner’s Green Coffee Trading export contracts
Open questions flagged:
- Nordic brewing standard verification (from previous ingest) still outstanding
- Phenylindane neuroprotective properties: emerging research only — not yet established clinical fact; flag before marketing use
- CoE price premium data (Traore et al., 2018) reflects a specific competitive auction context; may not fully generalize to direct-trade Salvadoran micro-lot pricing
2026-04-27 — Ingest: Scott Rao ∙ Espresso Extraction — Measurement and Mastery (2013)
Source: Espresso Extraction: Measurement and Mastery by Scott Rao (2013) (~100 pages, self-published) File moved from: raw/Import/ → raw/Brewing/
Context: User confirmed that Kaiserblick roasts varieties and blends for coffee shops using espresso machines, in addition to filter coffee. All espresso-specific content is therefore fully in scope.

Key connections to existing wiki:
- Roast development underdevelopment risk (Roasting) is a direct practical concern for Kaiserblick’s light roast espresso lots — links Roasting ↔ Espresso Extraction ↔ Roasting Service
- Roast age / CO₂ for espresso directly updates Coffee Freshness with a brewing-method-specific freshness recommendation
- Alkalinity/softening risk for espresso is actionable for coffee shop customers in El Salvador and European hard-water markets — links Brew Water Quality ↔ Espresso Extraction ↔ Green Coffee Trading
- Burr quality and PSD extend Grind with the most detailed treatment of grinder mechanics in the wiki
- Refractometer connects Coffee Refractometer ↔ Roasting Service (profile development QC) ↔ Cupping (Cata) (objective extraction data alongside sensory evaluation)
Contradictions / tensions flagged:
- Light roast philosophy vs. roast development: Rao warns that the trend toward very light roasting frequently causes underdevelopment and low extraction. Kaiserblick must manage DTR carefully to achieve both light color and full cellulose porosity.
- Water softening: Rao’s caution (high-bicarbonate + softening = extraction failure) is consistent with Lingle’s warning but more specific to espresso — now documented in Brew Water Quality
Open questions:
- El Salvador water alkalinity levels — relevant to whether local coffee shops face the softening risk Rao describes
- VST basket availability in El Salvador — Rao’s recommended precision baskets may require import
2026-04-27 — Ingest: Scott Rao ∙ The Coffee Roaster’s Companion (2014)

Contradictions flagged and resolved:
- Caffeine and roast: El Arte del Café states ~10% caffeine loss from roasting; Rao states caffeine is virtually unchanged and increases per gram in darker roasts due to mass loss. Both positions documented in
roasting.mdwith attribution. - Roasting for espresso: Previous wiki reflected common view that espresso requires darker roast; Rao argues no special adjustment needed if development and extraction are correct. Both positions documented in
espresso-extraction.md.
Key connections to existing wiki:
- Three Commandments (ROR + DTR) directly inform Roxanne Fredericksen’s light-roast profile development at Roasting Service — the most technically demanding aspect of specialty light roasting
- Washed-process roasting implications link Coffee Processing ↔ Roast Development: Kaiserblick’s washed El Salvador lots should be charged hot and roasted aggressively to achieve proper inner-bean development
- Water activity measurement for green coffee strengthens Green Coffee Trading export proposition — sharing aw + moisture data with European roasters is a premium traceability differentiator
- Roast defect diagnostics in Roast Defects are actionable for Roasting Service QC: grassy = underdevelopment, cardboard = baked ROR, smoky = low airflow
- Blending framework in Blending directly applies to Kaiserblick’s espresso blend development for local café customers
Open questions flagged:
- What roasting machine does Kaiserblick currently use? Machine type determines optimal charge temperature range and roast time targets.
- Does Roxanne Fredericksen currently use data-logging software (Cropster or equivalent)? Essential for managing ROR in real time per Rao’s framework.
- Caffeine contradiction: Rao’s position (no loss) vs. El Arte del Café (~10% loss) — not yet verified against peer-reviewed research; both cited as is.

Index updated: Added advection-and-diffusion, channeling, coffee-bed-hydraulics, pourover-technique, brew-water-crafting to Brewing Science section; updated extraction, grind, brew-water-quality descriptions; added jonathan-gagne-physics-of-filter-coffee to Sources.
Key connections to existing wiki:
- Darker roast → lower AEY finding (Ch. 9) directly connects to Roast Development and Roasting Service: Kaiserblick’s light roasts will achieve higher AEY in filter than the same coffee roasted darker — a quality metric argument for light roasting
- Dense/hard bean → more fines → clogging links Coffee Bed Hydraulics ↔ Coffee Varieties ↔ Pourover Technique: high-altitude Salvadoran Arabicas may need grind adjustment guidance for café customers
- Natural vs. washed AEY difference links Coffee Processing ↔ Extraction: customers should not target identical brew parameters across different process lots
- Water crafting framework in Brew Water Crafting is directly actionable for Green Coffee Trading export customers in Germany, Switzerland, Austria — markets with highly variable tap water
- Bloom physics (CO₂ degassing) connects Pourover Technique ↔ Coffee Freshness: lighter/fresher roasts produce more CO₂ and may need longer blooms
- Percolation vs immersion (advection-and-diffusion) provides scientific basis for why Brewing Methods produce different body and clarity
Contradictions / tensions flagged:
- AEY upper bound: Extraction previously stated 22% as the ceiling; Gagné’s data support 22–23.5% as achievable with quality grinders. Nuanced in Extraction with attribution to both sources.
- Alkalinity primary role: Brew Water Quality previously framed alkalinity mainly as a flow/equipment issue; Gagné establishes it as the primary flavor parameter. Updated with both framings.
Open questions:
- Nordic brewing standard verification (carried from previous ingest) still outstanding
- El Salvador water alkalinity — still not documented; relevant for local café customer guidance
- Roasting machine type at Kaiserblick — still outstanding
