Ingredients (coffee-cherry to coffee process)

No traditional “recipe” ingredients with measurable quantities—this is a whole-process coffee-making experiment using:

  • Coffee cherries
    • Varieties mentioned as a mixture of “Gesha” and “Koutura/Coutura”
    • Exact amounts not specified
  • Bucket of water
    • Used to separate cherries by flotation/sinking
  • Beans/seeds only after extraction
    • No washing step—honey process described (syrup/sugars remain on the seeds)

Equipment & prep

  • Freezer-to-thaw setup
    • Cherries were frozen, then thawed before use
  • Containers/bowls
    • Bowls for floaters vs sinkers
    • Extra bowls for manually cutting/opening cherries
  • Trays
    • Food dehydrator trays
  • Food dehydrator
  • Moisture meter
    • Preset to coffee
  • Roasting tools (3 attempts)
    • Pan + burner/stovetop (first attempt)
    • Coffee roaster from Amazon (second attempt)
    • Air fryer (final successful attempt)
  • Storage
    • Jar for storing/cooling/degassing coffee beans
  • Manual extraction tools
    • Implied: hands and cutting/chopping to extract beans

Step-by-step method (key timings/temperatures/technique cues)

1) Thaw cherries and separate by quality (float vs sink)

  1. Thaw frozen cherries in water (bucket of water).
  2. Sort based on floating vs sinking:
    • Floaters go into one bowl
      • Described as potentially having broken shells, air inside, rotted, or overripe
    • Sinkers go into another bowl
      • Described as generally better quality (tighter/shinier skin)
  3. Cut open a few cherries to inspect interiors:
    • “Good” beans look denser
    • “Crappier” beans look shriveled / less dense

Variation mentioned:

  • Considered doing a “floater batch” vs “sinker batch”, though results mostly came from the overall honey-process method and later manual sorting.

2) Manually extract seeds from cherries

  1. Chop/burst cherries to remove the beans.
  2. Weed out extra-wrong-looking cherries during extraction (qualitative filtering).
  3. Effort note:
    • Described as feeling like “hours,” later clarified as about 15 minutes for some portion.
  4. After extraction:
    • Seeds divided into lower-quality vs higher-quality sets.
  5. Seeds begin to brown while sitting:
    • Attributed to oxidation in air

3) Drying (“honey process” drying without washing)

Explicitly the honey process:

  • After popping beans out, they were not washed
  • Sugars/syrup remain on the seeds → contributes to browning and sweetness
  1. Spread seeds onto trays:
    • Goal: one even layer per tray
    • Lower-quality: two full trays
    • Higher-quality: one half tray
  2. Load into a food dehydrator
    • “Good stuff” on top; lower quality below
  3. Dehydrate until dry:
    • Later tested moisture with a coffee moisture meter
    • Target: about ~10% moisture
    • Measured result reported: 9.6% moisture
  4. Expected endpoint:
    • Seeds should become crispy / “rock solid”

4) Roasting attempt #1 (pan) — fails (burnt)

  1. Roast in a pan on the burner.
  2. Roast half first (experiment).
  3. Heat produces smoke early.
  4. Expected milestone: reach “first crack” (light roast marker)—avoid roasting indefinitely.
  5. Results:
    • Beans turned black, then ash/charcoal before first crack
    • Test bean: burnt, hard, crispy, with limited coffee flavor

5) Roasting attempt #2 (electric coffee roaster) — fails (burns again)

  1. Preheat roaster to about 240°F (per manual).
    • Preheat time: ~10 minutes
  2. Load beans and cook per manual:
    • Leave ~15 minutes (approx; monitored)
  3. Results:
    • Beans started crackling but quickly ended up burned to hell again

6) Research-driven conclusion (why it kept failing)

Chef concludes (from “research”):

  • Gesha beans are notoriously difficult to roast and scorch/burn easily (tendency to burn outside)
  • Honey-processed beans are also harder to roast
  • Combined factors made it a “very bad decision” for a first roasting attempt

7) Roasting attempt #3 (air fryer) — successful

Chef’s “madeup temperature profile” with an air fryer:

  1. Preheat air fryer to 300°F for about 3 minutes
  2. Load beans; shake/mix
  3. Keep at 300°F for 4 minutes
  4. Increase to 325°F for about 1.5 minutes
  5. Increase to 375°F for 2 minutes
    • No early signs of burning; minimal coffee smell
  6. Increase to 400°F
    • Smoke appears; pops/crack sounds noted
    • First crack reportedly heard developing
  7. Done point:
    • Near an approximate mark near 130 (likely time/temp reference)
  8. Cooling:
    • Beans cooled quickly using a container/jar setup
  9. Char on outside:
    • Char present; chef tries to rub/rake char off by hand
    • Mentions it might look better with a “rock tumbler” (not used)

8) Degassing/resting and storage

  1. Put roasted beans into a small jar
  2. Cover loosely so CO₂ can escape
  3. Rest time: at least 24 hours
    • CO₂ release continues; flavor develops per common claims
  4. After resting:
    • Chef reports beans taste like coffee, not plant material anymore

9) Brewing/serving the coffee

  1. Brew setup (subtitles mention “drip through,” but specifics aren’t detailed)
  2. Tasting:
    • Not too bitter
    • Pretty mild
    • “Nice flavor”
  3. Rating:
    • 7.5/10, then up to 8.5/10 due to “from scratch” effort

Chef tips & key takeaways (from what’s said)

  • Quality sorting matters
    • Sinkers generally had denser beans than floaters
    • Shrinking/shriveled seeds correlated with lower quality
  • Honey process changes behavior
    • Sugar on seeds → brownness and affects roasting difficulty
  • Roast target
    • Aim for first crack as a light roast marker; avoid roasting indefinitely
  • Failure causes
    • Gesha + honey likely scorch/burn easily → requires careful temperature control
  • Air fryer approach worked
    • Slow-ish ramp, avoid high heat too early
    • First crack heard at the higher heat stage
  • Cooling quickly matters
    • Implied by immediate transfer to a cooling step

Common mistakes shown (implied by failures)

  • Pan roasting too fast / too hot
    • Beans turned black → ash/charcoal before first crack
  • Coffee roaster settings too aggressive
    • 240°F then ~15 minutes still led to burning for these beans
  • Exterior scorching remained
    • Chef suggests mechanical tumbling could remove char more effectively

Plating / serving suggestions

  • Serve in cups; chef pours and tastes immediately after brewing
  • Sharing vibe emphasized (“Cheers” / “finish it all”)
