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)
- Thaw frozen cherries in water (bucket of water).
- 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)
- Floaters go into one bowl
- 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
- Chop/burst cherries to remove the beans.
- Weed out extra-wrong-looking cherries during extraction (qualitative filtering).
- Effort note:
- Described as feeling like “hours,” later clarified as about 15 minutes for some portion.
- After extraction:
- Seeds divided into lower-quality vs higher-quality sets.
- 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
- Spread seeds onto trays:
- Goal: one even layer per tray
- Lower-quality: two full trays
- Higher-quality: one half tray
- Load into a food dehydrator
- “Good stuff” on top; lower quality below
- Dehydrate until dry:
- Later tested moisture with a coffee moisture meter
- Target: about ~10% moisture
- Measured result reported: 9.6% moisture
- Expected endpoint:
- Seeds should become crispy / “rock solid”
4) Roasting attempt #1 (pan) — fails (burnt)
- Roast in a pan on the burner.
- Roast half first (experiment).
- Heat produces smoke early.
- Expected milestone: reach “first crack” (light roast marker)—avoid roasting indefinitely.
- 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)
- Preheat roaster to about 240°F (per manual).
- Preheat time: ~10 minutes
- Load beans and cook per manual:
- Leave ~15 minutes (approx; monitored)
- 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:
- Preheat air fryer to 300°F for about 3 minutes
- Load beans; shake/mix
- Keep at 300°F for 4 minutes
- Increase to 325°F for about 1.5 minutes
- Increase to 375°F for 2 minutes
- No early signs of burning; minimal coffee smell
- Increase to 400°F
- Smoke appears; pops/crack sounds noted
- First crack reportedly heard developing
- Done point:
- Near an approximate mark near 130 (likely time/temp reference)
- Cooling:
- Beans cooled quickly using a container/jar setup
- 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
- Put roasted beans into a small jar
- Cover loosely so CO₂ can escape
- Rest time: at least 24 hours
- CO₂ release continues; flavor develops per common claims
- After resting:
- Chef reports beans taste like coffee, not plant material anymore
9) Brewing/serving the coffee
- Brew setup (subtitles mention “drip through,” but specifics aren’t detailed)
- Tasting:
- Not too bitter
- Pretty mild
- “Nice flavor”
- 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”)
